I build high-performance React/TypeScript micro-frontends and design systems as Senior Frontend Engineer.
ArmeniaWhat I'm looking for
Senior Frontend Engineer with 6+ years of experience building large frontend applications on React and TypeScript, including SaaS platforms and high-performance interfaces. I focus on frontend architecture—modular systems, stable module boundaries, and real-time products with intensive data processing.
At Alfa-Bank (Senior Frontend Developer), I designed a unified frontend platform for corporate banking with Module Federation and micro-frontends, including clean module boundaries and independent deployments used by 5+ internal teams. I also developed integration patterns across SSR/SSG, code splitting, lazy loading, and REST API integration approaches to reduce integration bugs and data synchronization issues.
Previously at Quintegro (Senior Frontend Developer), I implemented a scalable React/TypeScript architecture for a SaaS product, reworked state management on Effector + FSD, and refactored legacy code toward FSD and Clean Architecture. I’ve also delivered enterprise web features at Accenture, improved client-side performance, and integrated Jest/React Testing Library and linting into CI/CD pipelines, while supporting code quality through reviews and mentoring.
