About

I am a frontend engineer specializing in building scalable web applications with React and TypeScript. I design modern, high-performance user interfaces, integrate complex APIs, and participate in architectural decision-making across full-stack systems. As the primary frontend developer in a fast-moving startup environment, I led the development of production-level applications, collaborated closely with backend engineers, and helped shape the overall architecture and development processes.

Integrated complex REST APIs, authentication flows, payment systems, and real-time communication features.

Built reusable application templates and component systems that accelerated development for other team members.

Re-architected an existing platform extension from scratch, reducing system errors and significantly improving reliability.

Improved performance of critical application components by optimizing data processing and frontend logic.

Authored and maintained technical documentation for application architecture, APIs, and development workflows.
