Design-driven.
Performance-obsessed.
I’m Jonathan, a Full Stack Engineer based in Oceanside, California. I specialize in building fast, user-centric web experiences using React, TypeScript, and Next.js.
Because of my background in Graphic & UI Design, I speak Figma fluently. This allows me to bridge the gap between creative vision and technical implementation. I care deeply about smooth interactions, pixel-level detail, and writing code that scales.
I’ve worked on everything from modernizing patient-facing healthcare apps under strict compliance standards to architecting early-stage startup MVPs from zero-to-one. I thrive in collaborative environments where engineers wear multiple hats and product ideas move fast.
When I'm not coding:I’m usually digging through crates for vinyl records, hunting for the best tacos in San Diego, or watching football—whether I'm backing SDFC locally or cheering on Barça with the Penya Blaugrana San Diego.
