What I'm looking for

I'm looking to build responsive, high-performing web products where I can work with React, Next.js, TypeScript, API integrations, performance optimization, and full-cycle frontend development.

I've built 150+ responsive websites at Boomerang Media, including 110+ React and Next.js projects, with 100% W3C validation and average Lighthouse/PageSpeed scores above 95.

I've also delivered commercial sites for Dreamfin and Agroforsunka, and improved Instalook and Daki.market through interactive pages, responsive product layouts, and deep refactoring of a 40,000+ line legacy codebase. I enjoy full-cycle frontend development, REST API integrations, performance optimization, animations, and building interfaces that improve user experience and conversion.
