01 — About

Who I am

I'm a Computer Science student at Wrocław University of Science and Technology and a self-taught full-stack developer working in the Next.js / TypeScript stack. I design, build and ship real, deployed products end-to-end — from React UIs to PostgreSQL databases on Supabase, authentication, validation, tests and CI.

I care about clean, strictly-typed code, secure data handling and a polished user experience. I'm looking for a remote full-stack role — anywhere in the world — where I can take ownership, learn from a strong team, and have visible impact on a real product. I work comfortably in English.

Leveling up

01
Full-stack architecture
Designing data models, server actions and auth flows end-to-end — thinking about the whole system, not just the UI.
02
Databases & data modelling
Going deeper with Prisma, PostgreSQL and Supabase — relations, migrations and type-safe queries.
03
Testing & CI
Writing meaningful tests with Vitest and React Testing Library, and wiring GitHub Actions so every push is verified before it ships.
04
Web performance
Core Web Vitals, caching, lazy loading and measuring real-world performance on production apps.
