Persist AI intern, UC Davis CS senior, full-stack systems builder

Hi, I'm Eugene Cho.Software Engineer

I'm a UC Davis CS senior and software engineering intern at Persist AI. I build backend-heavy full-stack systems across healthcare, education, and bioinformatics, with recent work in agents, real-time collaboration, and production APIs.

About

A bit about me.

Hi, I'm a senior studying Computer Science at UC Davis and a Software Engineer Intern at Persist AI. I like building practical software where backend systems, product detail, and real workflows meet.

Recent work spans multi-agent platforms, patient intake systems, course planning tools, and bioinformatics software.
