About

Fintech & SaaS · 7+ years · React & TypeScript

I don't just build features — I challenge requirements, propose UX improvements, and measure outcomes.

Senior Frontend Developer specializing in fintech with 7+ years of experience building complex web applications in React and TypeScript. At Rosbank (Société Générale group), I single-handedly architected and shipped a currency control platform from scratch — replacing 3 legacy systems, unifying workflows for 50+ users, and reducing production bugs by 40%. At T-Bank (40M+ customers), I cut CI/CD build times by 80% and led the Webpack → Vite migration. I thrive in high-ownership environments where I can drive architecture, mentor engineers, and deliver measurable business impact.
