7+ years in the JavaScript/TypeScript ecosystem. I architect high-performance Next.js platforms, lead large-scale migrations from legacy stacks, and tune Core Web Vitals to production budgets. I integrate LLM-powered features into web products and use AI-assisted workflows to ship faster — most recently as the sole frontend engineer behind the Next.js migration of a major automotive media portal.
Expertise
[ SECTION // 01 ]
[ MIGRATIONS & NEXT.JS ARCHITECTURE ]
Transforming legacy web systems into modern Next.js environments: breaking monolithic layouts into maintainable component architectures, structuring predictable data flows, and modernizing state management. 76+ component design system built solo on my last migration.
[ PERFORMANCE & CORE WEB VITALS ]
Optimizing heavy platforms to strict production budgets: SSR/SSG rendering strategies, payload reduction with backend teams, asset discipline. Proven result: Lighthouse 95/100 with zero CLS on a high-traffic media portal.
[ AI-POWERED FEATURES & WORKFLOW ]
Integrating LLM APIs (Gemini, Claude) into products — bots, content pipelines, structured-data output for LLM discoverability — and using AI-assisted development (Cursor, Claude) to cut implementation and research time.
