I've built complex React interfaces for fintech and brokerage products serving multi-million-user bases. At Ifellow, I develop an enterprise application for managing banking-product pilot programs, including typed multi-step forms, audience segmentation, approval workflows, document management, and external integrations.
At T-Bank, I designed and shipped a UI Kit that accelerated new feature-screen development by 35%. I also migrated state management from Context API to Redux Toolkit, cutting re-renders by 22%, and built a backend-configured dynamic form engine.
Previously at Zeal Technology, I developed a trading-data analysis SPA with real-time WebSocket quote updates under one second and alerting for critical market events. I improved performance through bundle splitting and contributed to REST APIs, WebSocket services, and trading-data integrations.
I've also mentored junior developers, conducted technical interviews, reviewed code, and built automated test coverage for business-critical functionality.
