- Built a scalable React component library and shared state patterns that improved consistency across product teams.
- Refactored 1,000+ single-tenant Next.js nodes into a unified multi-tenant platform with Redis-backed caching and SSR-first delivery.
- Created internal tools for GraphQL query generation, content operations, and analytics to shorten feedback loops for non-engineering teams.
- Owned deployment and observability workflows across Docker, Kubernetes, GitHub Actions, Prometheus, and Grafana.
Full-Stack Product Developer
Full-stack product developer with 12+ years of experience building high-performance, consumer-facing products end to end, from backend systems and platform architecture to polished, intuitive user interfaces. I work across React, TypeScript, Node.js, and Next.js, and I do my best work on interaction-heavy products where performance, usability, and system design directly shape the user experience at scale.
