Fullstack Developer with 6+ years of experience building fast, scalable web and mobile products.

  • Gdańsk, Poland 🇵🇱
  • Fullstack Developer @ Wakacje.pl
  • Open to new opportunities

I'm Kamil Zieliński — a Fullstack Developer with a strong frontend orientation. My main stack is JavaScript, TypeScript, Next.js, React and React Native, which I use to build responsive, scalable and user-friendly applications. I currently work at Wakacje.pl (the largest travel portal in Poland) and previously delivered products for startups and software houses including Pstryk, DeveloArt and Automex.

About me

Hello! Thanks for stopping by my personal website.

I'm Kamil Zieliński. I've been working in web development for over 6 years, doing both the coding you see on the screen (frontend) and the stuff that happens behind the scenes (backend). I know how to manage projects using methods like Waterfall and Agile. But what really gets me excited is making websites and apps that are easy for everyone to use and look good too!

I'm really into JavaScript and TypeScript, which are languages used to build websites. I also know a bunch of frameworks that make building websites even easier, like React, Next.js, Node.js. I love learning about new web tools and features.

In my career, I've primarily worked as a full-stack and mobile developer, but I also have experience leading development teams and delivering software solutions for a wide range of companies — from large corporations to innovative startups.

I believe that good communication is super important in any job.

I'm good at adapting to different situations, working efficiently, and always trying to do my best. My experience has taught me how to solve problems and lead teams, but I'm also happy to work with others to get things done. I'm excited about the chance to work together and make cool stuff!

I'm looking forward to the possibility of working with you!
