What I'm looking for

I’m looking for a role where I can lead frontend architecture and ship accessible, high-performance React experiences. I want to work closely with design, run meaningful experiments, and keep improving engineering practices—with AI supporting better craftsmanship.

I’m a Senior Software Engineer with 7+ years specializing in frontend architecture, TypeScript, and modern React applications. I lead frontend initiatives that optimize user experience and connect design intent to engineering execution, with a strong focus on design systems, performance, and accessibility (WCAG).

In recent roles, I’ve built and evolved complex UI (including a Rich Text Editor powered by Lexical) while maintaining strict WCAG and performance standards. I also drive data-driven frontend growth through end-to-end A/B testing, improve engineering practices via QA and mob-testing, and mentor engineers—plus I’ve led curriculum development at ReDI School to strengthen AI literacy for 2,400+ students.
