About this Gig

I specialize in embedded firmware development for IoT, wireless, industrial, and custom electronic products. My experience includes low-level driver development, RTOS-based systems, wireless communication, hardware bring-up, debugging, validation, and production support.

Completed work includes:

Firmware development for STM32, ESP32, nRF52/nRF53, EFR32, TI MSP430, and FPGA-integrated systems
BLE, Wi-Fi, LTE, GNSS, LoRa, Zigbee, Thread, and sub-GHz wireless applications
Real-time embedded systems using FreeRTOS and Zephyr
Peripheral driver development for SPI, I2C, UART, CAN, USB, Ethernet, ADC, PWM, and DMA
Bootloader, OTA update, and secure firmware implementation
Low-power optimization for battery-powered devices
Hardware bring-up, debugging, validation, and reliability testing
Sensor integration and communication protocol development
Prototype firmware through production-ready deployment

I focus on clean architecture, stable firmware behavior, efficient debugging, and reliable product development from prototype to production.
