Frontend Team Lead and React/TypeScript architect driving scalable, high-performance platforms.
UkraineWhat I'm looking for
I am a Frontend Team Lead and architect with 10+ years building large-scale JavaScript applications and 3+ years in technical leadership roles. I specialize in React and TypeScript and deliver production-grade systems with strong focus on performance and scalability.
I design and evolve frontend architecture, state management strategies, SSR implementations, and real-time data flows, while modernizing legacy codebases and improving Core Web Vitals. I have built web, desktop (Electron) and cross-platform mobile products, implemented real-time chat and in-game overlay features, and optimized rendering for high-interaction interfaces.
I mentor senior engineers, establish engineering standards and CI/CD practices, and coordinate across product, backend, and design to ensure reliability and observability in production. My work emphasizes clean architecture, performance optimisation, and consistent delivery across complex, high-load environments.
