About Me

Based in San Francisco, CA, I’m a full-stack engineer building production internal tools, Salesforce-connected workflows, and AWS-backed data/AI systems for enterprise users.

I led development of AbbVie’s first production GxP-compliant multi-agent system and have experience translating business workflows into production software, shipping AI chatbots, full-stack dashboards, and iOS features across consecutive internships at AbbVie.

Comfortable in JavaScript/TypeScript, Python, SQL, C/C++, and Swift, I move fluidly between backend logic and pixel-perfect front-ends, always chasing the cleanest path from problem to polished solution.
