I've built and deployed production Embedded C firmware for microcontroller-based IoT hardware at Gold Sikka Limited, taking products from requirements through deployment.
I develop low-level UART, SPI, I2C, and CAN drivers and bring up hardware using JTAG, flash programmers, oscilloscopes, and logic analyzers. I also build Python scripts for sensor parsing, log analysis, and firmware test automation.
At Pantech ProEd, I developed firmware across STM32, ESP8266, ESP32, and Arduino platforms, including LoRa-based subterranean telemetry systems and multi-sensor safety monitoring.
I've connected devices to AWS IoT Core through MQTT and REST APIs, including an ESP32-based automated gold coin dispenser and a mine safety environmental monitoring network.
