Hi there! I’m a Senior Software Engineer specializing in frontend development with React and TypeScript. I enjoy building clean, intuitive user interfaces for product-driven software. I'm a big fan of thoughtful user experiences.

I’ve spent the last several years building high-traffic, user-facing applications, with an emphasis on usability and maintainability. I value good testing practices, accessibility, and observability as part of delivering reliable product experiences.

I’m currently interested in senior frontend roles where I can stay hands-on, collaborate deeply with product teams, and focus on building great software.
