6+ years shipping safety-critical software across medical devices, IoT, and AI. I build voice agents, embedded systems, and the weird side projects that keep me curious.
From bare-metal firmware to production GenAI pipelines.
Safety-critical systems in healthcare, IoT, and AI.
Safety-critical smart-home systems for independent living — shipping speech-to-text, translation, and LLM replies under strict patient-safety and privacy requirements.
Firmware for respiratory and sleep apnea devices at a global medtech company — plus a flow-sensor calibration algorithm that improved accuracy tenfold.
Side projects, startups, and things I use every day.
Engineering deep-dives, maker projects, and volunteer work.
Camera-based system using background subtraction and a YOLO neural network to detect parking occupancy, reaching 91% accuracy. Published as a paper during my degree.
