Full-stack developer based in Poland. 6 years of experience building applications with TypeScript, React, Next.js and Node.js. I work across the stack, from user interfaces and APIs to databases, third-party integrations and cloud infrastructure. Lately, I’ve been exploring how AI can improve both the products we build and the way we build them.
