What I'm looking for

I'm looking for a team that values ownership, clear communication, and thoughtful engineering, where I can build scalable user-facing products, improve frontend architecture and performance, and support team growth.

At Purrweb, I build B2B and FinTech frontend products from architecture through delivery, including a personal finance system built with React, TypeScript, and Redux.

I designed a modular DDD-based architecture and a 30+ component UI kit adopted by 5+ teams. I reduced LCP from about 2 seconds to 0.5 seconds through caching, request deduplication, and TanStack Query, while helping reach 88% test coverage and reduce failed CI/CD deployments by 39%.

Previously at Addamant, I delivered responsive, SEO-optimized React and Next.js interfaces for cultural events, online education, e-commerce, and administration platforms serving US and UAE clients.

I enjoy turning complex business logic into clean, scalable UI, collaborating closely across product teams, and helping developers grow through mentoring and structured feedback.
