I build AI agents and full stack apps.

I’ve shipped projects across voice agents, computer vision, developer tools, and onchain infrastructure. Recent work includes a top-five OpenAI Codex hackathon project, a Pump Fund investment, and award-winning builds at Caltech, UC Berkeley, UC Davis, UCSB, UCR, etc.

faqs.

EECS at UC Berkeley, class of '28. Started shipping in middle school with a JavaScript Mother's Day card, then VEX robotics captain (PID + odometry for autonomous routines), then FBLA nationals (mobile + computer programming), now hackathons. Valedictorian out of Ayala HS, GPA 4.69. Currently involved across several technology organizations at UC Berkeley, building whatever catches my interest in my free time.

Honestly, whatever's pulling me. Random corporate and collegiate hackathons every few weeks, side projects with friends that start in a discord call at 2am, design work for people who vibe with my taste, and a rotating stack of personal builds I'll ship when they're good. Always one project shipping, one being rebuilt, one fresh, usually too many at once. If something's interesting enough to break my sleep schedule for, I'm probably already on it.

I just finished at Walmart Global Tech and am searching for summer 2027 internships, high-signal collaborations, and post-grad full-time roles beginning in 2028. I’m most interested in agentic systems, computer vision, generalist software engineering, and product-focused frontend work. Email me with the role and I’ll reply within 48 hours.

If it's a hackathon, pick something that demos in 90 seconds and could keep going for a year. If it's a personal project, pick the part of the stack I haven't shipped before. Either way, the rule is novel tech + a constraint that forces taste. Lapis came from "can crypto conditions enforce vesting without lawyers," Opal came from "can an agent actually queue up with you," Yolodex came from "can you turn a YouTube clip into a trained YOLO model overnight."

Bun > npm. Vite > CRA. TypeScript strict. FastAPI for the backend, Next.js for the frontend, GSAP for motion. AI work in Python or Bun depending on which one's faster to ship. I optimize for how fast I can rebuild something, not how clever the architecture looks.
