What BUILD is
BUILD is the line where Polargate writes software: public websites, customer products, internal portals, iOS and Android apps, AI features and integrations with the systems you already run. Senior engineers do the work and use AI inside it, in their own tooling, instead of selling it as a separate product. Every project ends with the code, the database and the hosting in accounts your company owns.
How it works
Every engagement starts with a paid Discovery Sprint: two weeks of interviews, an audit of what you already have, a data model, an architecture decision and a scope you can say no to. It ends with a fixed price for the build, calculated from evidence rather than from a first meeting.
The build then runs in weekly deployments to an environment you can open at any time. The first shipped iteration lands between week four and week eight. It is a version in production with real data behind it. Before a release goes live it passes an audit loop where several review passes look for bugs, architecture problems, accessibility failures, slow pages and security holes, and every finding has to survive a sceptical second reading to count. On one internal platform, that pass left 59 confirmed findings: one blocker, seven high, twenty five medium and twenty six on user experience and accessibility. All of them were fixed and deployed.

Who it is for
We don't take every project.
We would rather tell you now than halfway through. If you recognise yourself on the left, let's talk.
It fits if
- You need a website, a portal or an app that does not exist yet, or one that has run out of road
- You want the code, the data and the hosting in accounts your company owns
- You prefer a fixed price before work starts to an open hourly bill
- Someone on your side can decide and give the project a few hours a week
- You care that Google and AI assistants can read it from day one
It is not for you if
- You are after a cheap template or a site put together over a weekend
- You want it to live on a platform you cannot leave later
- Nobody on your side can review screens or make decisions
- You need people to bill hours without a clear goal
For example: 2 languages live on the site, Spanish and English. Global Dynamic Security Group
What you get
What you take away.
Everything is written down before we start, and everything stays in accounts your company owns.
01Deliverables
- 01
A Discovery document with scope, data model, architecture decisions, risks and a fixed price for the build
- 02
A working application deployed on your own Vercel project, with a staging and a production environment
- 03
Your own Supabase backend: Postgres schema, row level security on every table, authentication, storage and edge functions
- 04
Source code in a Git repository your company owns, with continuous integration that blocks a merge when types, lint or tests fail
- 05
Multilingual structure where the project needs it: one route per language, localized slugs, bidirectional hreflang and per-language sitemaps
- 06
Search and AI-search layer: server-rendered HTML per route, JSON-LD, sitemap and a robots policy that lets answer engines read the site
- 07
iOS and Android builds published under your own developer accounts, with over-the-air updates, when the project includes an app
- 08
Security baseline: HTTP security headers, a real 404 page, restricted CORS on server functions, secrets kept out of the repository
- 09
Handover pack: environment variables, admin accounts, a runbook and the written audit report of what was found and fixed
02How it runs
- 01 · Week 1 to 2
Discovery Sprint
Interviews with the people who will use the thing, an audit of the systems you already run, a data model, an architecture decision and a scope written in plain language. It ends with a fixed price and a delivery plan, and the document is yours whether or not you continue.
- 02 · Week 2 to 4
Foundations
Design direction, database schema with row level security from the first migration, environments, continuous integration and the first screens in a place you can open. Nothing is built on a platform you cannot leave: the repository, the backend and the hosting are created in your accounts.
- 03 · Week 4 to 8
Build to the first shipped iteration
Weekly deployments, a short written update with each one and a running list of decisions. The goal of this stage is a version in production with real data where someone can finish an actual task, not a demo. Scope changes are priced before they are built.
- 04 · Week 8 onwards
Audit, launch and handover
Several review passes over correctness, architecture, accessibility, performance and security, with every finding checked by a second reviewer before it counts as real. Then the launch, the handover pack and, if you want it, a move to the CARE retainer for maintenance and evolution.
For example: 38 Spanish and English routes prerendered as static HTML. Santo Domingo Bay
Timing and budget
How we quote.
No price list and no hourly billing during a build. After a short call you get a written quote for your project.
- Timeline
- About two weeks of Discovery, then the first iteration in production between week four and week eight. Larger platforms are delivered in phases.
- Team
- Our team scopes and builds it. Pedro Ciordia, founder and CTO, sets the architecture and reviews every release. You talk to the people building it.
- How the price is set
- Fixed price, set at the end of the Discovery Sprint and sent as a private quote. What moves it: languages, modules, integrations and how much of an old system has to come along.
For example: 11 modules delivered in Phase 1. Elite Smart Build
