About

Senior Frontend Engineer with 3+ years building real-time web platforms and AI-powered interfaces. I work at the intersection of complex UI and distributed systems — from WebSocket-driven collaboration tools to RAG-based document intelligence platforms. What I've shipped: • Reduced a critical data pipeline bottleneck by 99% (6–9 hours → under 5 minutes) through ETL rewrite and query optimization • Improved page load performance by 35% via memoization, lazy loading, and code splitting — hitting 90+ Lighthouse scores • Built and shipped an AI Chatbot SDK adopted by 5+ client teams, cutting manual customer escalations by 60% • Engineered a design system (18+ components, ShadCN + Storybook) deployed across 5+ product surfaces, accelerating frontend velocity by 30% I use Claude and Codex daily as force multipliers but I know when the output is wrong and I fix it. AI-augmented development has become a core part of how I ship faster without cutting corners. Stack: React · TypeScript · Next.js · Node.js · GraphQL · WebSockets · LangChain · Pinecone · AWS · Docker · Redis I thrive in async-first, high-ownership environments where there's real surface area to shape — not just a backlog to execute.
