What I'm looking for

I'm looking to build modern, accessible web products, lead frontend migrations, and mentor engineers while contributing across React, TypeScript, APIs, and full-stack systems.

I've spent 15+ years building web applications, most recently owning frontend development across Corsair Gaming's multi-app architecture after joining Gamer Sensei.

I led major platform modernization work, including a Rails 4-to-7 upgrade and an AngularJS-to-React migration that reduced bundle size by about 65%. I also raised site-wide accessibility audit scores from 54% to 97% while aligning with WCAG and ADA standards.

My work spans React, TypeScript, JavaScript, Node.js, Rails, Python, APIs, databases, and ecommerce. I've delivered payment flows, scheduling and authentication systems, analytics tooling, headless CMS sites, multiplayer games, and esports analytics products.

I've led critical migrations, managed and mentored engineers, and maintained test coverage that reduced production bug reports by nearly 30%. I enjoy turning Figma designs into responsive, pixel-perfect interfaces and making legacy systems easier to evolve.
