A continuation of P2, the ESP32 Ultrasonic Radar. I treated the finished radar as a device under test and characterized it across six tests, with limits set before measuring and before/after data for every fix.
pulseIn timeout, the same case runs at ~86 ms.
pulseIn stallpulseIn waited out a 48 ms echo every ping. A 30 ms timeout cut the loop from 106 to 86 ms.An HC-SR04 sweeps from 15° to 165° on an SG90 servo while C++ firmware draws range rings, a live sweep line and persistent detections on a 128×64 SSD1306 OLED. No PC in the loop.
Wire.begin(32, 33).Taken from gear geometry to dimensioned drawings to printed, tested parts on a Raspberry Pi 4 controlled Q-arm.
sign_up(), pack_products()A Parallax PING sensor watching for a car, a servo doing the work, and a stepped sweep with threshold logic to avoid false triggers.
servo.write(90) snapped the gate open, so I replaced it with a stepped loop for smooth motion.Aluminum foil contact bumpers, continuous rotation servos, and a state machine that reroutes on contact.
Three agents (campaign, email, media) behind a FastAPI backend, with a React/Vite frontend scaffolded from scratch.

The bridge from logic design to real RTL and processor datapaths. Starting with the HDL and sequential logic chapters, alongside Logic Design this term.
LUTs and flip-flops through simulation, synthesis and place and route, with every example in both Verilog and VHDL, from FIFOs to clock-domain crossing.
I got into engineering the way a lot of people get into cars: wanting to know what's underneath. Formula 1 is where that never wore off, since a tenth of a second there is a design decision someone made months earlier.
Off the bench I'm in Forza tuning things that don't need tuning, or out on a trail on the bike.
Open to Summer 2027 co-op terms in hardware systems, test and verification, and embedded work, and always up for a good hardware problem in the meantime.
