Custom software development for products that need to work in production.

What we build

Web applications

Customer portals, internal tools, dashboards, marketplaces and SaaS products. Usually TypeScript and React on the front, with a typed API behind it, so features ship quickly and bugs show up at build time rather than in front of your users.

Mobile apps for iOS and Android

We build cross-platform apps with React Native and Expo, one codebase for iOS, Android and the web, and take them through store review and release. Our own apps Grosz and Gymeat are built and released this way.

Backends and APIs

Services in Java (Spring), Python (FastAPI, Django) and Node.js / TypeScript (Hono, Express): REST APIs with OpenAPI contracts, authentication, payments, background jobs, integrations with third-party systems, and PostgreSQL schemas that hold up as the data grows.

MVPs for startups

The smallest version of your idea that real users can try. We help you decide what to cut, then build it on a stack that won't need a rewrite once it works.

Modernisation of existing systems

Legacy Java or Python applications, slow deployments, missing tests, an unmaintained server. We stabilise first, then improve step by step while new features keep shipping: no big-bang rewrites.

Why a small senior team

• You talk to the engineers. No account managers relaying messages. The person on the call is the person writing the code.
• We've done the whole job before. Our products cover the whole lifecycle: design, API, mobile release, payments, SEO, monitoring and support.
• Weekly working software. Every week you see a demo on real infrastructure, not a status report.
• You own everything. Code, cloud accounts and documentation are yours from day one.
• Based in Poland, in the EU. Central European Time, GDPR as standard, and a working day that overlaps with the UK, the rest of Europe and the US morning.

How a project runs

1. Discovery call: free, 30–60 minutes, about goals, users and constraints. 2. Written estimate: scope, milestones and a fixed price, or a monthly rate for open-ended work. 3. Build in one- or two-week iterations with a demo each time. 4. Launch and support: we deploy, monitor, fix and keep improving for as long as you need.
