Custom software, built by an engineer with 10+ years shipping.
ENZ builds custom software — mobile apps, web platforms and APIs — for companies that need a senior team, with security, tests and documentation from the very first commit.
No sales layers — you talk to the people who build it.

What we build
Custom software development for real problems — the right stack is a consequence, not a starting point.
Mobile Apps
Your company in your customer's pocket — one codebase, both stores.
- One codebase for iOS and Android: less to build and less to maintain than two native apps
- Works offline and syncs later — built for the field and bad connections
- App stores without the drama: continuous releases and updates
Flutter
Web Platforms
The system your operation opens every day — with no spreadsheet on the side.
- Processes trapped in spreadsheets become flows with rules, history and permissions
- Your team's back office and your customer portal in the same product
- Simple to use: adoption without a heavy training program
Laravel · React · Vue
APIs
Your systems talking to each other — and keeping up with your growth.
- Integrations that end double data entry between ERP, partners and product
- Handles demand spikes without taking your operation down
- Monitored in production: you hear about the problem before your customer does

How ENZ works
Principles that don't rely on promises — they live in the pipeline.
Security from day one
Code review, OWASP practices and secrets management on every project. Security isn't a final step: it's a merge requirement.
Verifiable quality
Test suite and CI/CD in everything we build. Nothing reaches production without going through the pipeline — and you can audit it.
Living documentation
Docs validated alongside the code, in the same repository. Zero drift between what's written and what's running.
Direct communication
You talk to the people who build. No management layers, no telephone game: technical decisions straight from the source.
Founded by an engineer with 10+ years in production
Samuel Cecílio has been writing software professionally for more than 10 years — from mobile apps to platforms handling millions of requests. He worked as a Staff Engineer and Tech Lead, depending on the role at each company, at Loft, will bank, Idez Digital and iConnections (US), building products across real estate, banking and events for the capital markets. At ENZ, he is the one who signs off on the architecture and reviews what goes to production.

Frequently asked questions
How do we work together?
Fixed-scope project (scope and price defined up front) or a monthly retainer for continuous engineering. Either way: weekly deliveries, the repository yours from day one, and no lock-in. At the end you choose — your team takes over with a documented handover, or ENZ keeps going with support and evolution.
Who actually builds my project?
The founder signs off on the architecture and reviews what goes to production. When the project needs more hands, senior engineers join — never unsupervised juniors, never invisible outsourcing.
What's a typical project timeline?
Well-defined MVPs: 6 to 12 weeks. Larger projects are phased into deliveries that create value from the very first weeks.
What's the risk for me?
Low by design: the repository is yours from day one, with documentation and CI/CD. Working deliveries every week — you can stop at the end of any sprint and take everything that's been built.
