Frontend Product Engineer specializing in React, Next.js, TypeScript, and Design Systems, with strong experience in data-heavy systems and AI-powered applications.

I build scalable, high-performance web products and focus on shipping fast while maintaining strong engineering quality.

• Build and scale frontend architectures (React / Next.js)
• Design and implement design systems used across multiple apps
• Optimize performance, UX, and developer experience
• Work on data-heavy dashboards and large-scale systems
• Build AI-powered features (RAG, semantic search, vector DBs)

• Built dashboards handling large-scale datasets (~18GB) with optimized rendering & caching strategies
• Improved frontend performance by 30–50% using Next.js SSR, ISR, and code splitting
• Designed a reusable design system, reducing UI development time by ~30–40%
• Built AI RAG pipelines using Weaviate & pgvector for semantic search
• Contributed to zero-downtime production migrations (Rails 5 → Rails 6)
• Improved debugging & reliability using Sentry / BugSnag observability
