Embedded Linux and Firmware Development Engineer

Embedded Firmware and Embedded Linux Engineer with strong experience in STM32 development, RTOS based systems and custom Yocto Linux platforms. Skilled in SPI and I2C driver development, Device Tree integration and low level hardware debugging. Experienced in real time sensor processing, telemetry systems and embedded Linux service integration. Combines firmware engineering, hardware analysis and system level integration for reliable embedded solutions.

Developed real time firmware for STM32F4 using FreeRTOS with interrupt driven sensor handling and optimized task scheduling. Implemented SPI drivers for nRF52 and integrated SPI NOR Flash with LittleFS under Zephyr for reliable embedded data storage. Built a custom Yocto based embedded Linux system including I2C kernel driver development, Device Tree overlays and systemd service integration. Integrated MQTT telemetry and Node RED visualization while performing hardware debugging using JTAG, SWD, oscilloscope and GDB. Led an electronics QA team focusing on PCB level failure analysis and validation using oscilloscope and logic analyzer. Developed a SPI Flash evaluation system for radiation environments supporting satellite payload qualification with improved anomaly detection. Created a secure STM32 bootloader with CRC validation, structured flash layout and UART based firmware update mechanism.
