I build scalable full-stack web applications, APIs, and AI-integrated platforms with measurable performance gains.

I've built full-stack products at PayPal, Pentangle Tech Services, Dreamway Media, and River Bend Data Solutions, delivering React and Next.js applications, Node.js and Python APIs, and scalable PostgreSQL-backed services. At PayPal, I improved database and GraphQL response latency by 25%, reduced redundant AI/LLM service calls by 60%, and established test coverage of 97%.

I enjoy owning systems end to end—from accessible frontend experiences and state management to secure authentication, microservices, CI/CD, testing, and deployment. My work has improved engagement, reduced production bugs, accelerated releases, and supported high-volume transactional and analytics platforms.
