I build embedded products that ship and keep working in the field. Ten-plus years in, my firmware runs on more than 5,000 deployed units across industrial automation, robotics, consumer IoT, and edge AI. Most went out knowing they'd see heat, vibration, bad power, and users who don't read the manual. They still work. Along the way I cut an ESP32 wearable's sleep current from 80 uA to under 10 uA, ran a zero-brick OTA across a 5,000-unit fleet using secure boot and TLS, and took products through FCC and CE at accredited labs. What sets me apart from most firmware contractors is that I also own the board and the box. So when a sensor reads noisy, I know whether it's the driver, the layout, or the analog front end, because I drew all three. Manufacturability and reliability don't get bolted on at the end. They're decided on day one, while the part placement, the thermal path, and the enclosure seal are all still on the table. I design for certification from the schematic forward, not as a scramble after tooling. WHAT I DO DAY TO DAY • Firmware. C/C++ on ESP32 (ESP-IDF and Arduino), nRF52840 (nRF Connect SDK / Zephyr), STM32, and ARM Cortex-M/A, on FreeRTOS or bare-metal. BLE, Wi-Fi, sub-GHz, MQTT, and the low-power work to make a coin cell last. Plus 8+ years of embedded Linux (Yocto, device tree, U-Boot, PREEMPT-RT) and Jetson with CUDA, TensorRT, and GStreamer. • PCB design. Schematic capture and multi-layer layout, not a hand-off to someone else. I brought up a custom NVIDIA Jetson Orin carrier from a blank schematic to production, and laid out a compact wearable board (Nordic BLE, sensors, Li-Po) where every millimeter mattered. Comfortable with analog front ends, high-speed routing, power integrity, and EMC/ESD, with DfM baked in so the board is buildable at volume. • Mechanical CAD. SolidWorks (Fusion 360 too) in PDM-managed environments: parts, assemblies, and drawings for real enclosures. Injection-molding constraints, IP68 silicone overmold, gasket and tolerance work. I've carried housings from 3D-printed prototype to a tooled-mold production direction. RECENT WORK • An autonomous 4-wheel ROS 2 platform on Jetson fusing IMU, lidar, radar, and camera (NDA) • A driver-assist weather-state estimator on Jetson using Kalman multi-sensor fusion • A sealed multi-sensor wearable where I owned firmware, PCB, and the IP68 enclosure end to end (NDA) Got a product that needs to become real hardware, not a prototype on a desk? Send me the spec or a schematic and I'll tell you where the risks are. Happy to go deep work one-on-one.
