About Me
Passionate about creating exceptional digital experiences through innovative technology
I'm a Poland-based full-stack developer specializing in Next.js, NestJS, and TypeScript with deep experience in AI-powered applications, SaaS platforms, and travel tech.
Over the past few years, I've built products from MVP to launch, integrating complex APIs (Amadeus, Stripe, Supabase) and deploying to scalable cloud environments. My projects range from AI-powered travel planners to aviation analytics platforms — all with a strong focus on UI/UX design and performance optimization.
