Tomasz Czajka

Freelance Full-Stack Developer (Angular, React, Python/Django, C#/.NET)

Open for work

Hi, I'm Tomasz, a freelance full-stack developer based in Poland. I build modern web products with clean architecture and practical business impact.

I work across the full stack: from pixel-perfect Angular and React frontends to backend services in Python/Django, C#/.NET, and TypeScript/Node.js. For data, I typically use PostgreSQL and MongoDB. I'm also AWS Cloud Practitioner certified, comfortable managing EC2, S3, and cloud infrastructure. I'm ready to introduce AI-driven development to your team: structured AI-assisted code reviews, automatic bug detection, and Playwright testing. Not vibe coding, but focused tooling that measurably speeds up delivery. Whether it's a greenfield product, a legacy rescue mission, or a complex integration, I focus on quality, speed, and reliability.

Got a challenge? Let's talk. I'm always open to interesting projects, collaborations, or a good technical debate.
