Mateusz M.

I build and ship full-stack web applications end-to-end — from prototype through frontend, backend, database, and production infrastructure — for clients who want one person who owns the whole system rather than coordinating a team. My core stack is TypeScript/React/Next.js/Astro.js on the frontend and Python/FastAPI with PostgreSQL on the backend. I also work with React Native and Tauri for cross-platform mobile and desktop apps. A key part of how I work: I deploy to self-hosted infrastructure (Docker, CI/CD pipelines) rather than defaulting to managed platforms, which means I understand and control the full request path from client to server to database — not just the app code. I've also built systems to strict data-handling and security requirements for clients in regulated contexts, and I'm currently completing a cybersecurity-focused CS degree. I care about writing maintainable code and understanding the systems I build, not just getting them to run. Expect daily communication, short turnaround times, and full transparency throughout the project. Feel free to reach out and we can get started quickly.
