I build, review, and debug embedded, IoT, and automotive systems where firmware, electronics, sensors, connectivity, and vehicle networks must work reliably under real-world conditions — from concept to production-ready prototype. Hi, my name is Oluwatunmise — an Embedded Hardware Engineer and Firmware Developer focused on ESP32/STM32 firmware, IoT hardware, PCB design and layout, automotive diagnostics, PCB bring-up, sensor integration, and low-power connected devices. My work sits where hardware, firmware, communication protocols, cloud telemetry, and real-world testing meet. I help clients move from unstable prototypes and proof-of-concept builds to reliable, production-ready devices. That can mean owning a design from concept through prototype-ready manufacturing files, reviewing existing ESP32 firmware and project files, running clean DRC/ERC checks, debugging GPIO and pin mappings, stabilizing sensor logic, fixing Wi-Fi, BLE, MQTT, HTTP/REST, and JSON telemetry issues, troubleshooting brownouts, boot loops, and resets, or bringing up a new PCB against the actual wiring. I select and validate components, optimize for DFM, and deliver files ready for JLCPCB, PCBWay, and Shenzhen assembly. I've supported IoT, consumer electronics, robotics, industrial automation, and automotive development from prototype to validation, including diagnostic systems communicating with ECUs across CAN, CAN-FD, RS-485, and OBD-II working with live data, DTCs, proprietary PIDs, and BCM/ECM/TCM modules.
