Front-end & Full-Stack Developer• based in Wrocław, Poland 🇵🇱
Actively looking for internship / junior position (Front-end or Full-Stack)
I specialize in building modern, performant web applications with React and Next.js, always backed by solid TypeScript. Recently I've expanded into full-stack territory using Prisma and Supabase, with a strong focus on testing ( Vitest + React Testing Library).
- Workout Tracker – Full-stack fitness tracking app with Next.js 16, Prisma, Supabase (auth + DB), Server Actions, and 100% test coverage (Vitest + RTL).
- Sport App – Next.js league browser with dynamic routing, error boundaries, API integration, fully tested, deployed on Vercel.
- Cocktail App – SPA with React, TypeScript, React Router v6, search & pagination, unit tested with Vitest.
- Weather App – Minimalist weather app with debounce, dynamic icons, Open-Meteo API, tested and refactored into reusable components.
