Middle Front-End Developer & UX/UI Designer

I build full-stack web apps — and design the interfaces.

I’m Tymur, a developer based in Warsaw. I work across the stack in TypeScript — frontend, backend, and the data model — and design as I go. My work ranges from web apps and internal tools to developer tooling. Recent projects include ExdBots, a research data platform, and an e-commerce store.

03 About
Photo

I’m Tymur Mustafaiev, a front-end developer and UX/UI designer based in Warsaw. I like working across the whole stack — interface, backend, and data model — usually on the same project, in TypeScript. Most recently I was a front-end developer and lead UX/UI designer at Softica Tech, and I’m finishing a Master’s at PJATK.

My work spans a few areas: e-commerce, developer tooling, research platforms, and Telegram apps. It tends to involve building both the product and the system underneath it. I’ve also worked with the PJATK XR Lab and the University of Amsterdam on research tooling. More on the experience page.
