I’m a results-driven Embedded Software Engineer with 2+ years of industry experience delivering production-grade firmware for ARM Cortex-M microcontrollers (STM32F4/L4, ESP32). I build bare-metal and FreeRTOS-based systems, focusing on low-level device drivers and hardware-software integration across UART, SPI, I2C, CAN Bus, and LoRaWAN.

In my recent role at Micro Vision Embedded Systems, I developed hierarchical state-machine firmware for a BWC Water Heater, covering standby, heating, error, and lockout modes per SRS. I adhered to MISRA-C coding guidelines for safety-critical compliance, owned the full lifecycle (SRS/SDD through implementation, unit testing, and CI/CD deployment via Azure DevOps), and executed structured unit and integration test plans (40+ test cases).

I also built a LoRa Wireless Sensor Network on STM32L476 + ESP32, implementing a SPI IMU driver from scratch with <2ms data latency at 200Hz (DMA-based transfer). I applied power management between LoRa transmission windows to reduce average current draw by ~40%, automated log parsing and regression testing with Python, and validated 500m+ outdoor range with <1% packet loss.

Earlier, I developed embedded C firmware for IoT prototypes on STM32 and Arduino platforms, wrote and tested peripheral drivers for I2C sensors and UART modules, and supported hardware-software co-verification on prototype PCBs. I’m also motivated by quality and reliability—my approach is rooted in structured documentation (SRS/SDD/Test Plans), disciplined testing, and continuous improvement, backed by an M.Tech in Electrical Engineering and GATE-qualified preparation.
