I'm a software developer from Poland, passionate about fullstack web development. I specialize in building dynamic frontends and robust backends. Open to fullstack, frontend, or backend opportunities.
I started my journey in web development with a passion for building interactive and useful websites. Along the way, I earned my diploma as a Programming Technician, which gave me solid foundations in both frontend and backend technologies.
I enjoy creating projects that are practical and easy to maintain. Currently, I work with React, TypeScript, and Node.js, and I’m exploring Svelte to experiment with modern frontend development. I like solving real-world problems through code and continuously learning new tools and techniques.

Implemented video processing features including trimming, cropping, compression, and multi-format conversion. Built with React frontend and Express backend, deployed with AWS S3, CloudFront, and Docker containers.
Anti-Hate Foundation Website
My first paid project - a website for a foundation combating hate speech and supporting victims of online harassment. The website serves as an informational platform and will eventually include a blog, chatbot, and newsletter system. Originally built with HTML, CSS, and JavaScript, this project represents my first professional client work.
Children's Party Company Platform
Developed the frontend for a children's party company platform using React and TypeScript. The platform featured a blog system, gallery management, and admin dashboard functionality. Collaborated with a backend developer through REST API integration. The website was fully deployed with HTTPS and custom domain before the company unfortunately closed down.
