Bruno Dzięcielski

Full-Stack Engineer

I build things for the web — from real-time collaborative tools to 2D games that run in the browser. I like working across the full stack and I’m drawn to problems where performance and user experience meet.

I use TypeScript daily, and I’m most at home when building real-time systems, optimizing heavy UIs, or finding ways to make complex things feel simple. I care about clean architecture, maintainable code and making the development process better for everyone on the team.

I’m also currently pursuing a Bachelor of Engineering in Computer Science at Silesian University of Technology.

Now

At Gamecode, I build online casinos slot games with PixiJS and work on a custom in-house game engine used across projects. I collaborate closely with designers to bring visuals, animations and audio to life.

I’m also building Refina.io — a real-time platform for collaborative refinement of work items, with live synchronization to Azure DevOps and Jira. I am responsible for the entire system architecture, including both frontend and backend.
