What I'm looking for

I'm looking to lead frontend platform, architecture, and modernization work where I can improve developer velocity, web performance, and reliable delivery while mentoring engineers.

At GoHighLevel, I lead frontend platform modernization across roughly 120 micro-frontends. I led a Webpack-to-Rsbuild rollout that cut build time by 67%, reduced development builds by 70%, production builds by 65%, and JavaScript payload by 18.6%, with zero reported regressions.

I built a manifest-driven promotion pipeline for artifact traceability and an MF runtime plugin serving 70+ apps with asynchronous remote loading, improving LCP and FCP by 25%. I also created reusable Rsbuild wrappers, ESLint rules, configuration tooling, and Cursor skills that helped teams independently own migrations.

Previously, I led three developers through migrating around 1,800 Vue files from Vue 2 to Vue 3 and improved memory use across micro-frontend apps by 10–30%. I’ve also built a 60+ component Vue library, a custom rich text editor, and integrations that reduced initial JavaScript chunks by 30%.

My product work spans Square Yards, PropVR, and Polydimensional, where I built immersive real-estate and collaborative VR experiences using Vue, React, A-Frame, Three.js, WebSockets, and full-stack JavaScript. I enjoy combining platform architecture, practical tooling, and mentoring to help frontend teams ship better products.
