About Me

Building useful, thoughtful software

I'm an EECS student at Diablo Valley College, independent reinforcement-learning researcher, and founder focused on practical AI products. I work where product engineering, AI, and education meet—taking ambitious ideas all the way to clear, testable experiences.

  • 🔭 Building Regrade, a more transparent, student-centered grade-review product.

  • 🚀 Preparing Unvibe for founder fellowships, an AngelList presence, and a future Y Combinator application.

  • 🌱 Researching reward shaping for accessible AI tutoring for community-college learners.

  • 🧠 Exploring LLM systems, context design, model routing, and reinforcement learning.

  • 🏆 Three-time SF Hacks 2026 award winner with Sortify.

  • 🎯 Open to internships, research collaboration, hackathons, and ambitious product work.
