Hi, I'm Jeff 👋

  • M.S. Computer Science @ USC, graduating May 2027
  • Embedded & systems: co-built a portable NIR biosensing device (Arduino Nano 33 BLE Sense, I2C sensor, BLE) behind an IEEE paper, and a real time C++/OpenGL rendering engine from scratch
  • Also applied AI / ML engineering — retrieval fine-tuning, agents, and the evaluation harnesses around them
  • C/C++, Python, C#/.NET, TypeScript, backend + cloud
  • I care about verifiable results — controlled comparisons, independent checks, honest negative results over cherry picked numbers
  • Coauthor, IEEE Transactions on Human Machine Systems (2026)
  • Looking for 2027 new grad roles in Embedded Systems Engineering / AI Engineering
  • Reach me: LinkedIn · Portfolio · Email
