What I'm looking for

I want a Frontend Team Lead role where I can drive architecture, mentor engineers, and deliver scalable, accessible user experiences while continuing technical growth.

I am a results-oriented Senior Frontend Engineer with 8+ years building high-performance, scalable, and accessible web applications for enterprise and consumer audiences.

I have led cross-functional teams as the primary architect, driving architectural decisions, mentoring engineers, and delivering features used by audiences ranging from 10K to over 300M users.

My technical expertise centers on React.js, TypeScript, Redux, testing with Vitest and Jest, performance optimization, component reuse, and WCAG accessibility standards.
