I design, review, and bring up PCBs and embedded hardware for ESP32/STM32, IoT, and automotive devices, from schematic design and PCB layout to tested prototypes and production-ready manufacturing files. Hi, my name is Oluwatunmise, an Embedded Hardware Engineer, PCB Design Engineer, and Firmware Developer focused on schematic capture, PCB layout and routing, ESP32/STM32 firmware, IoT hardware, prototype bring-up and testing, sensor integration, automotive diagnostics, and low-power connected devices. My work sits where circuit design, firmware, communication protocols, cloud telemetry, and real-world testing meet. I help clients move from concepts, unstable prototypes, and unfinished designs to reliable, manufacturable boards. That can mean owning a design end to end: component selection, schematic, 2-layer or 4-layer PCB layout, JLCPCB prototype orders, and hands-on bring-up and validation. It can mean reviewing an existing schematic, legacy design, or AI-generated circuit, verifying footprints and pinouts against datasheets, and flagging issues before layout. Or it can mean debugging GPIO and pin mappings, stabilizing sensor logic, fixing Wi-Fi, BLE, MQTT, HTTP/REST, and JSON telemetry issues, and troubleshooting brownouts, boot loops, and resets on real hardware. 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. WHAT I CAN HELP YOU BUILD PCB Design, Layout, Bring-Up & Manufacturing Schematic capture, schematic review, and multilayer PCB layout in KiCad, Altium Designer, EasyEDA, Eagle, and OrCAD/PADS. Stackup definition, controlled-impedance and differential-pair routing, high-speed signal integrity, mixed-signal grounding, RF module placement with antenna keep-out, and EMI/EMC pre-compliance. Clean DRC/ERC, DFM, and SMT assembly optimization. I deliver Gerbers, drill files, BOM with MPN and LCSC/DigiKey part numbers plus alternates, pick-and-place/CPL, assembly drawings, STEP/3D models, PDF schematics, and editable source files ready for JLCPCB, PCBWay, or Shenzhen PCBA. I can also order the prototypes, test them on the bench, and document the results. ESP32 / STM32 Firmware & Connected Devices ESP32 (C3/S3/P4, WROOM/WROVER), STM32, nRF/Nordic BLE, Arduino.

I build and test real boards on the bench, not just CAD files. I read datasheets carefully, catch design issues early, and push back when something looks wrong. I choose cost-effective, sourceable components with active lifecycle status and second sources. I communicate clearly in English, work well with milestones and design reviews, and hit the dates I commit to.
