Background & Focus

Engineering grounded in mathematical rigor, physical modeling, and craft.

I'm a software engineer and robotics programmer based in Michigan building full-stack platforms, physics-based simulations, and on-device computer vision. My focus centers on architectural simplicity, deterministic performance, and hardware-aware optimization.

Outside of software development, I play competitive soccer and cello. The spatial awareness, split-second tactical decisions, and disciplined daily training required on the pitch carry directly into how I approach control theory, kinematics, and robust systems architecture.
