I'm looking for a remote Frontend Engineer role focused on React and TypeScript. I want to work on complex products, take ownership of features, contribute to technical decisions, and collaborate with an international team. I'm especially interested in product-focused teams that value architecture, performance, and user experience.

I build maintainable React products for fintech, healthcare, analytics, and marketplace platforms.
Russian FederationWhat I'm looking for
I've built frontend products across fintech, healthcare, analytics, and marketplaces for teams including Friendly IT, Feedvisor, JetRuby, and Exceed Team.
At Friendly IT, I built a complete React and TypeScript payout flow for a B2B fintech platform, integrated REST APIs and GraphQL workflows, and prevented stale exchange-rate responses during financial calculations.
At Muffin’s, I evolved three healthcare applications, improved doctor-user communication with WebSocket, introduced E2E testing, and used Sentry metrics and alerts to reduce user-reported bugs by 40%.
I also launched an AI review analytics MVP using Python, Playwright, FastAPI, React, and the OpenAI API. I contribute to architecture, code review, design systems, requirements decomposition, mentoring, and predictable delivery.
