I build satellite modems. As one of the first hundred employees at Amazon Leo, I carried its custom modem silicon from MATLAB simulation through seven chip iterations to production firmware on orbit. Now I lead a seven-person firmware team and build AI-first, agentic test infrastructure. I started in machine-learning research, and next I want to help bring frontier AI to product.
