A technical portfolio covering mechanical design, embedded firmware, robotics, full-stack software, and AI-agent experiments.

Landing page captured for the 2026-09-05 issue.

Field notes

The portfolio breaks each build into mechanical, electrical, firmware, and software layers rather than presenting projects as undifferentiated case studies. Its rover uses per-wheel throttle thresholds and an auto-stop watchdog, while the Duelists system combines a custom PCB, 100 Hz motion telemetry, a game server, and OBS overlays. A separate mechanical section covers conveyor systems, load measurement, accessibility-oriented equipment, and a Northwestern lab fixture.
