I design and build embedded hardware and firmware for connected devices — from schematic capture and PCB layout through firmware bring-up and field deployment. My background is mechatronics engineering with hands-on production experience leading hardware R&D for an industrial client. Embedded hardware and firmware: ESP32 and STM32 based designs, schematic capture and PCB layout/review in KiCad, component selection and BOM development, sensor integration (NFC, RFID, IMU, analog front-ends), and communication protocols including UART, SPI, I2C, Wi-Fi, MQTT, and BLE. I take projects from concept through Gerbers, prototyping, and manufacturing handoff. Currently leading hardware R&D as a Team Lead at an energy company, where I developed an NFC-based fuel transaction reader that cut fraud by 30 percent, and led hardware validation work that reduced terminal maintenance costs by over 70 percent. Beyond hardware, I also build the software layer around embedded systems when a project calls for it: Python/FastAPI backends, REST APIs, and AI-assisted tools such as document Q&A systems, so I can support a full device-to-dashboard build if needed. I deliver structured, documented work — schematics, Gerbers, BOM, and test notes — ready for manufacturing or continued development.
