I build embedded firmware and Python-based IoT systems that connect sensors, controllers, gateways, dashboards, and industrial protocols. My work spans the device layer through Linux services, MQTT/Node-RED automation, monitoring, and technical troubleshooting.
- Embedded C/C++ firmware development and debugging
- Python device communication, automation, and test tools
- Raspberry Pi/Linux gateways and hardware integration
- MQTT, Mosquitto, Node-RED, Modbus, and BACnet integration
- STM32, ESP32/ESP8266, Arduino, sensors, and peripheral interfaces
- IoT dashboards, APIs, logging, diagnostics, and secure communication

I contributed embedded connectivity components to the Smart Steering Wheel team project: STM32F103 UART, ESP Wi-Fi/TCP connectivity with timeout and retry handling, a Python TCP service for version-aware firmware delivery, an STM32 SPI driver, and a Jetson Nano/MCP2515 CAN-interface prototype. I do not claim the team's final vehicle-level integration or production deployment.
