About
I architect and ship pixel-perfect, lightning-fast React/Next.js experiences that scale to millions of users. Over the last eight years I have led front-end strategy for SaaS, e-commerce and data-heavy platforms, cutting Core Web Vitals, boosting SEO traffic and raising NPS.
My code is clean, typed, tested and CI/CD-ready; my components are reusable, accessible, documented in Storybook and published to an internal npm registry so product, design and QA move in lock-step. From green-field Next.js apps to incremental React micro-frontend migrations, I turn Figma tokens into fluid experiences, mentor engineers on hooks, Suspense, Server Components and streaming SSR, and set the technical bar for the entire UI discipline.
