Jefferson Umanzor

Hey! I’m Jefferson, building backend systems and data-intensive applications.

Software Engineer Fellow at Google x BASTA
Software Engineer at UC San Diego (University Orgs)
Previous SWE & ML at NextHelper UCSD CSE Rosas Demolition

Computer Science @ UCSD (3.80 Major GPA & Provost Honors)

I build scalable systems and clean product experiences. I enjoy working across the stack, from TypeScript and Node.js services to databases, caching, and the interfaces that make systems feel fast and reliable.

Right now I focus on event-driven architectures, observability, and performance. I like designing APIs that are easy to use, hard to break, and simple to operate in production with strong auth, rate limiting, and meaningful metrics.

Outside of work, I enjoy photography and exploring new places. I like learning by building, iterating on details, and shipping projects that are practical and polished.

If you want to collaborate, talk systems, or share opportunities, feel free to reach out.
