Full-stack development

For: startups and product teams that need a web app, a new feature or an API built — and built to last.

What we build

• New products and MVPs, from idea to a deployed app
• New features and screens for your existing app
• APIs and backend services

React · Next.js · TypeScript · Python/FastAPI · Java/Spring Boot · GCP · Azure

How we build it

• Tests from the first week — unit, integration and end-to-end tests running in CI on every change
• Existing code left better than we found it — where we touch older code, we add tests first and refactor safely
• Working software early — weekly updates, no surprises
• Your team owns the result — clean, documented code and a handover walkthrough

Test automation

Already have an app, but no tests you can trust? We set up or rescue Playwright end-to-end tests, add coverage reporting and wire it all into CI — typically in 2–4 weeks.

Built with our own open-source tools: playwright-repl, nextcov and msw-terrarium.

How engagements work

1. Intro call (free, 30 min) — what you're building and where you're stuck.
2. Proposal — a written scope, timeline and fixed price within a few days.
3. Delivery — weekly updates, working software early, no surprises.
4. Handover — code, documentation and a walkthrough your team owns.
