What I'm looking for

I want to own UI architecture and rendering optimization, build scalable component design systems, and partner cross-functionally to deliver exceptional UX—where performance, accessibility, and quality gates are valued.

I’m a Senior Frontend Engineer with 5+ years of experience architecting and shipping responsive, high-performance web applications with React and Next.js. I prioritize fast renders, scalable component systems, and intuitive interfaces that hold up under product growth.

At Arbisoft, I redesigned React frontend architecture—reducing unnecessary re-renders by 30% and improving page load times by 20–30%—while elevating automated test coverage from 10% to over 60% and reducing production bugs by 25%. I’ve led UI migrations (Material UI v4 to v5, React Router v4 to v5), built reusable Storybook component libraries, and mentored junior engineers through code reviews and cross-functional collaboration.
