The distinction that decides a project like this: the mechanics were proven before the engagement started, so the time went into the part that was theirs. We build the product; the client launches the brand. That is the arrangement, and it only works if the handover is real: Renido owns the source code, had a launch date in writing before work started, and can check every figure on this page against a public ledger. Listings, search, media handling and enquiries were all ready. Our work was the local property types, the map behaviour and how agents actually get leads. Live inside a month.

The work sat where it always sits on this base: property types, territories, agent terms. Everything else on the list below arrived already built and proven on other engagements running the same base. **4**Applications and consoles shipped, each with its own permissions and release path*Delivered* **18**Platform modules reused unchanged from the Zillow Clone base*Delivered* **4**Decisions built for Renido: property types, territories, agent terms*Delivered* **3**Environments: development, staging and production*Delivered* **100%**Source code transferred to Renido’s own account*Contractual* ## What Renido actually needed. A property listings platform is not one feature. It is 22 distinct pieces that all have to work together before a single customer can be served, and most of them already existed and had been proven elsewhere. That distinction decides the shape of a project like this. A business does not need a dispatch engine or a settlement ledger to be invented again; it needs one that already works, then it needs the handful of decisions that make the product theirs rather than anyone else’s. The four below are the load-bearing pieces Renido would otherwise have spent months building before proving anything to a customer. Every platform of this kind has the same shape underneath: a set of load-bearing parts that must be correct before a single customer can be served, and a much smaller set of decisions that make it one business rather than another. Building the first set from zero would have consumed the window before the second was even discussed. That is the decision this engagement turned on, and it was taken before any code was written. **Renter**search, shortlist, enquire **Agent**listings, leads, viewings **Moderator**quality, fraud, takedowns **Admin**accounts, billing, ## What we settled before building. Which of the 22 pieces were already solved, and which were genuinely Renido’s to decide. Getting that line in the right place before any code is written is what keeps a Zillow Clone engagement short, and it is the conversation we would rather have honestly than optimistically. Where a scope genuinely does not fit a proven base, we say so during scoping and quote it as a custom build instead, even when that costs us the larger and more comfortable project. *01* #### Read the requirement back to first principles What must exist at launch, separated from what a business can add once it has customers. Those are different lists and conflating them is what makes projects run long. *02* #### Base versus build, capability by capability Each of the 22 capabilities assessed against the existing base as covered, partial or absent. Partial is treated as absent, because a half-fitting module costs more than a new one. *03* #### Mark what only Renido could decide 4 decisions were commercial or jurisdictional rather than technical. Those were theirs, and the engagement is where they got implemented. *04* #### Agree the line before writing anything 18 pieces reused unchanged, 4 built. Fixing that line up front is what turns a platform of this size into a six-working-day build. ## The parts that are genuinely hard. Not marketing difficulty, actual difficulty. These are the problems any serious Zillow Clone has to solve properly, and the reason building one from a blank page is a multi-quarter commitment rather than a sprint. Each was solved once, on the base, and has been under load on other builds since. Renido inherited the solutions rather than the problems. 01 ### Inventory quality decides the marketplace Stale, duplicated or fraudulent listings destroy trust faster than any feature can build it. **Already solved in the base:** Renter 02 ### Search is the whole experience Location, price and type filters have to feel instant across a large, constantly changing index. **Already solved in the base:** Agent 03 ### Lead routing An enquiry that reaches the wrong agent, or reaches them late, is a lost transaction. **Already solved in the base:** Moderator ## What we did not have to build for Renido. Every platform is made of the same mechanics underneath. This is the account of which of them Renido paid attention to, and which were already solved. Built from nothing, Renido would have meant paying for the mechanics again: the accounts, the sessions, the payments, the admin, the permissions. That work is real, it is slow, and none of it is what makes this product different from the next one. Starting from the Zillow Clone base moved that cost out of the project entirely, and the platform itself was deployed in 6 working days. What that bought is attention. The engagement went into the 4 parts that were actually different, instead of being spread thin across 22 of them. **Shipped ready-made***18 of 22* *01***Renter**search, shortlist, enquire *02***Agent**listings, leads, viewings *03***Moderator**quality, fraud, takedowns *04***Admin**accounts, billing, *05***API gateway**auth, rate limits, *06***Realtime channel**new leads, *07***Event bus**reindexing, async *08***Listing record**the published state of a *09***Moderation & fraud**verification, takedowns *10***Search & filters**location, price, type *11***Map & geo**boundaries, drawn areas *12***Lead capture**enquiry forms, dedupe *13***Lead routing**to the right agent, in *14***Viewing scheduler**slots, reminders, *15***Saved searches**matches over time, *16***store**listings, leads, *17***index**filters, map queries *18***Object storage**photos, floor plans **Made for Renido***4 of 22* *01***Property types**what you list *02***Territories**where you operate *03***Agent terms**who lists and on what *04***Brand & theming**every surface Build all 22 from nothing, mechanics included 18 already solved, so the effort went to the 4 that were not The account Shipped ready-made18 Made for this client4 Parts in total22 Build window6 working days The ready-made side is not a shortcut taken on quality. It is work that was already finished, and finished work does not get charged for twice. ## Everything that shipped with it. The full working set Renido took delivery of. Each piece was already built and proven on other engagements before this one started, which is the only honest reason a platform of this size stands up in six working days rather than months. None of it is a demo or a scaffold. These are the same components running under other businesses in other markets, which means the failure modes are already known and already handled rather than waiting to be discovered by Renido’s first real customers. ### Reused from the Zillow Clone base **Renter**search, shortlist, enquire **Agent**listings, leads, viewings **Moderator**quality, fraud, takedowns **Admin**accounts, billing, **API gateway**auth, rate limits, **Realtime channel**new leads, **Event bus**reindexing, async **Listing record**the published state of a **Moderation & fraud**verification, takedowns **Search & filters**location, price, type **Map & geo**boundaries, drawn areas **Lead capture**enquiry forms, dedupe **Lead routing**to the right agent, in **Viewing scheduler**slots, reminders, **Saved searches**matches over time, **store**listings, leads, **index**filters, map queries **Object storage**photos, floor plans ### Built for Renido **Property types**what you list **Territories**where you operate **Agent terms**who lists and on what **Brand & theming**every surface ## The base this was built on.

The filled blocks are the parts built for Renido. **Zillow Clone architecture** MXZillow / filled = built for this client Zillow Clone: the architecture, and one enquiry traced through it 4 client surfaces reach an edge of gateway, realtime channel and event bus. The base holds 8 services, of which Listing record is the source of truth, and 4 blocks are built for each client. Partner services sit behind a boundary and are chosen by the client. Underneath, one enquiry is traced across 5 steps. 18 of 22 blocks are reused unchanged. .fdiag{--dg-ink:#1c1618; --dg-sub:#6e6264; --dg-rule:#e3d2d5; --dg-rail:#faf5f6; --dg-card:#ffffff; --dg-accent:#a70d2a; --dg-track:#efe9ea; --dg-made:#a70d2a; --dg-made-ink:#ffffff; --dg-zone:rgba(28,22,24,.028); --dg-zone-core:rgba(167,13,42,.05); --dg-zone-line:#e3d2d5; --dg-zone-core-line:#f0c9d1} .lbl{font-size:13px;font-weight:700;fill:var(--dg-ink);letter-spacing:-.014em} .sub{font-size:10.5px;fill:var(--dg-sub)} .note{font-size:10px;fill:var(--dg-sub);font-style:italic} .mono{font-family:'JetBrains Mono',ui-monospace,monospace;font-size:10px; letter-spacing:.14em;text-transform:uppercase;font-weight:500;fill:var(--dg-accent)} .zn{font-family:'JetBrains Mono',ui-monospace,monospace;font-size:10px;font-weight:500; letter-spacing:.13em;text-transform:uppercase;fill:var(--dg-sub)} .zn.zh{fill:var(--dg-accent)} .tag{font-family:'JetBrains Mono',ui-monospace,monospace;font-size:7.5px;font-weight:500; letter-spacing:.1em;fill:var(--dg-accent)} .h2{font-size:30px;font-weight:800;fill:var(--dg-ink);letter-spacing:-.034em} .deck{font-size:13px;fill:var(--dg-sub)} .zone{fill:var(--dg-zone);stroke:var(--dg-zone-line)} .zone-core{fill:var(--dg-zone-core);stroke:var(--dg-zone-core-line)} .card{fill:var(--dg-card);stroke:var(--dg-rule)} .auth{fill:var(--dg-card);stroke:var(--dg-accent);stroke-width:2} .made{fill:var(--dg-made);stroke:none} .made-l{fill:var(--dg-made-ink);font-size:13px;font-weight:700;letter-spacing:-.014em} .made-s{fill:var(--dg-made-ink);font-size:10.5px;opacity:.95} .step{fill:var(--dg-card);stroke:var(--dg-rule)} .dot{fill:var(--dg-accent)} .dotn{fill:#fff;font-family:'JetBrains Mono',ui-monospace,monospace;font-size:11px;font-weight:500} .flow{stroke:var(--dg-rule);stroke-width:1.5;fill:none;marker-end:url(#mxzillow-ar)} .hot{stroke:var(--dg-accent);stroke-width:2;fill:none;marker-end:url(#mxzillow-ah);opacity:.55} .cnt{font-family:'JetBrains Mono',ui-monospace,monospace;font-size:10px; letter-spacing:.1em;fill:var(--dg-sub)} Zillow Clone MXZillow One documented build runs on this base.

The plain blocks are the ready-made platform and shipped as they are. The filled blocks are the ones we built for this client. 18 of 22 blocks were reused, 4 were built. ## Why none of this had to be written again. Each of these was already running on other builds of the same base before Renido started. That is the whole reason the platform was standing in days rather than months. **Renter**search, shortlist, enquire **Agent**listings, leads, viewings **Moderator**quality, fraud, takedowns **Admin**accounts, billing, **API gateway**auth, rate limits, **Realtime channel**new leads, **Event bus**reindexing, async **Listing record**the published state of a **Moderation & fraud**verification, takedowns **Search & filters**location, price, type **Map & geo**boundaries, drawn areas **Lead capture**enquiry forms, dedupe **Lead routing**to the right agent, in **Viewing scheduler**slots, reminders, **Saved searches**matches over time, **store**listings, leads, **index**filters, map queries **Object storage**photos, floor plans ## The decisions that were actually theirs. A ready-made base does not remove these; it removes everything underneath them. Each one below is a choice Renido had to make, and the engagement is where those choices got implemented. **01** ### Property types What is listed, and the rules each type carries. **Why it sat with them**Commercial rather than technical. The base already handles the mechanics underneath, so the engagement is where their own answer gets implemented. **02** ### Territories Where content may be streamed, and what happens outside those borders. **Why it sat with them**Commercial rather than technical. The base already handles the mechanics underneath, so the engagement is where their own answer gets implemented. **03** ### Agent terms Configured for Renido during the engagement. **Why it sat with them**Commercial rather than technical. The base already handles the mechanics underneath, so the engagement is where their own answer gets implemented. **04** ### Brand & theming The identity carried across every surface, so it reads as the client’s product rather than a template. **Why it sat with them**The base has to disappear behind their identity, so this is applied across every surface rather than skinned on one. ## What the six days actually cover. Our build time on a ready-made base, and nothing else. The parts that sit with the client are named plainly. Phase 01Phase 02Phase 03Phase 04 01 ### White-label The base is rebranded to the client’s identity across every surface. 02 ### Deploy Stood up on the client’s own hosting, not ours. 03 ### Publish Apps submitted from the client’s own developer accounts. 04 ### Handover Source, schema, deployment configuration and architecture notes transferred. The client supplies the hosting and domain, a verified developer account we publish from, branding and business details, an onboarded payment gateway with KYC complete, and any third-party API keys. Store review and merchant onboarding are controlled by Apple, Google and the payment provider, so those sit outside our window. [Every figure here is defined on the facts page](https://miracuves.com/facts/#fact-005). ## Who uses it, and for what. Rather than screenshots of a product that has moved on since delivery, this is the set of surfaces that shipped and what each one is for. Renido received every one of them, with the source behind each. Every role here is a separate application with its own permissions, its own state and its own release path. Building them to work as one system is most of the engineering in a platform of this kind, and it is the part that was already finished before this engagement began. Renter search, shortlist, enquire Agent listings, leads, viewings Moderator quality, fraud, takedowns Admin accounts, billing, ## What guards the platform. Built into the base and hardened across every engagement running it, rather than bolted on at the end of this one. Security added late is security that has to be argued for; the controls below were load-bearing from the first deployment. We claim the process, not a certificate. Miracuves does not hold ISO 27001, and we do not say otherwise: we build to the controls those frameworks require, and the evidence trail is there for an auditor who asks. #### Moderation & fraud verification, takedowns. Part of the base, so it was proven before this engagement started. #### Role separation Each surface sees only what its role permits, enforced server-side rather than hidden in the interface. #### Audit trail Who changed what and when, retained so a dispute can be answered with a record rather than a recollection. #### Transport and storage TLS end to end, credentials hashed, and anything sensitive at rest encrypted rather than merely obscured. #### Secrets handling Keys live in environment configuration on their own infrastructure, never in the repository we hand over. #### Card data stays out Payment details go to the gateway directly. The platform holds a reference, not a card number. #### Backups and restore Scheduled backups with a restore that was actually run, because an untested backup is a guess. #### What an auditor can actually see We claim the process, not a badge. Everything below was handed to Renido with the source. - Commit history for every change in the build window - Environment configuration separated from application code - Database schema with the migration that produced it - Deployment steps written down rather than remembered - Named team and a daily written progress record ## What it connects to. The connection points are part of the base and were already written and tested. Which providers sit behind each one was Renido’s decision, because those choices are commercial and jurisdictional rather than technical. This is also where the client-side dependencies live. Gateway onboarding, KYC approval and merchant review are controlled by the provider, not by us, which is why they sit outside the build window rather than inside it. Every one of these was already wired and tested in the base. What changed for Renido was which account sat on the far side of it. **Payments and payouts**gateway of their choosing **Identity and KYC**provider per jurisdiction **Maps and geocoding**tiles, routing, distance **Object storage and CDN**their bucket, their region **Media pipeline**transcode and delivery **Search and indexing**catalogue, filters, ranking **Market data feeds**rates and reference prices **Calendar and scheduling**availability and reminders **Push and transactional email**sent under their sender identity ## What it runs on.

Our build time only. Store review and merchant onboarding are controlled by Apple, Google and the payment provider, so they sit outside this window and we do not count them as ours. Stating that plainly is the difference between a build time and a promise we cannot keep. [Every figure here is defined on the facts page](https://miracuves.com/facts/#fact-005). The six working days are guaranteed. If a ready-made platform is not live in six, we keep working free until it is. A deadline nobody is accountable for is not a deadline, and a guarantee nobody pays for is not a guarantee. Throughout, a named team worked the build and sent Renido progress on WhatsApp every working day. There was never a week where nobody knew where it stood, which is the part clients tell us they notice more than the date itself. **6 working days** our side of the window The bar below is that window, day by day. Nothing outside it is counted as ours, and nothing inside it waits on someone else. #### What Renido supplied A build window only holds if both sides arrive ready. These sat with them, and the clock does not start until they are in place. - Hosting and a domain, on their own account - A verified developer account we publish from - Branding and business details - A payment gateway onboarded, with KYC complete - Third-party keys for the services they chose **Day 1**Base stood up and white-labelled*Base stood up and white-labelled* **Days 2-4**4 client decisions implemented*4 client decisions implemented* **Day 5**Deployed, apps submitted*Deployed, apps submitted* **Day 6**Source, schema and config handed over*Source, schema and config handed over* ## This base has done this before. Renido was not the experiment. The base underneath this build had already carried other businesses in other markets before it carried theirs, which is the whole argument for reuse: the risk was retired by somebody else’s project, not by this one. Across everything delivered since 2010 that is more than 9,000 products for over 6,000 businesses across 35+ industries. The eighty-four documented on this site are the ones with a named client and permission to show the work; most of the rest sits under NDA or white-label and is deliberately not here at all. Every number on this page is defined and sourced on a public facts ledger. That is the whole instinct behind how this company is run: most vendors ask you to trust them, and we would rather you checked us. If we cannot back a claim, we do not make it, which is why you will not find a satisfaction percentage or an unnamed award anywhere on this site. **18 of 22** Blocks reused unchanged on this build, each already under load on other engagements. *Architecture* **1** Documented builds running on the Zillow Clone base, in different markets. *Portfolio* **9,000+** Products delivered for more than 6,000 businesses across 35+ industries since 2010. *Company record* **3,900+** Apps published under clients’ own brands, counted per store release. *Company record* ## What we can state plainly.

Answered for this build. The same answers hold for every Zillow Clone in the portfolio. Do we own the code? Yes. The full repository history transferred to Renido’s own account at handover, with deployment configuration and architecture notes. It is not a licence and it is not held against a support contract. How is six working days realistic? Because 18 of the 22 pieces were built and proven before the engagement started. The six days are our build time on that base, not a calendar promise. What sat with Renido? Hosting and domain, a verified developer account we publish from, branding and business details, an onboarded payment gateway with KYC complete, and any third-party API keys. Will it look like everyone else’s? No. The base supplies mechanics, not identity. Branding, flows and every customer-facing screen were built for this product. Is this what the platform looks like today? This describes what was delivered in 2021. What happened afterwards was Renido’s to decide; the source transferred at handover. Clients move on, rebuild, or sell up, and none of that changes what was delivered or how it went. Would you have said no to this project? We are a good fit for a founder who wants a proven model launched fast, a deadline they can hold us to, and code they own outright. We are a poor fit for anyone who needs a team embedded in their office full-time, or who wants a blank page and a six-month roadmap. Being straight about that up front saves everyone a call. Who actually worked on it? A named team, not a rotating pool. Our leadership is public with real profiles rather than a stock-photo team page, and progress went to Renido on WhatsApp every working day of the build. ## Building something like this?

The theme header is position:fixed and its height is not constant (70px wide, 93px at 1280 where its own nav wraps).

Probing only y=1 finds the topmost bar and nothing else - which pinned the section nav at 32px, directly behind the header, for every logged-in user while looking perfect logged out. So walk down the top edge until we run out of bars and take the deepest.
