Junior Front-End Developer from Tarnowskie Góry, Poland — building web apps that solve real problems in the aviation industry, where I know the workflows from the inside.

I focus on React and TypeScript, and I care about shipping: every project below is deployed and running.

✈️ Aviation Destinations — live demo Generator of printable route-knowledge tests for airport staff, with a secured trainer panel. React · Vite · Firebase (Auth + Firestore) · React Router (Protected Routes)

🛫 Manual Boarding — live demo Seat-map generator for practicing manual check-in and aircraft section counting under time pressure. TypeScript · Vite · Playwright (e2e tests) · bilingual docs (PL/EN)

✈️ METAR Weather Viewer — live demo Aviation weather viewer: decode the METAR for any airport by ICAO code, with flight category, ISA deviation, relative humidity and a color-coded observation-freshness indicator. React · TypeScript · Vite · TanStack Query · Netlify Functions · Vitest · GitHub Actions CI

Shipping with CI (GitHub Actions), testing with Vitest + React Testing Library, and server state with TanStack Query — all now running in production on METAR Weather Viewer. Next up: Next.js, serverless functions (to proxy API keys), and databases.
