embedded systems / sensor integration / firmware update tooling
I build microcontroller-based systems and the software around them, from STM32 and ESP32 sensor integration with ThreadX and Zephyr RTOS to firmware update workflows. My projects also include web dashboards, Flutter applications, Python data tooling, and voice translation.
Technologies I have used across firmware, web, mobile, and Python projects.
