I am a Firmware Engineer with expertise in microcontroller programming, automation test equipment, and hardware debugging. My work focuses on creating efficient, scalable, and reusable firmware solutions for real-world applications.

This repository serves as my portfolio, showcasing my expertise in embedded software, peripheral driver development, and low-level hardware interaction. I specialize in firmware development for microcontrollers, including STM32, ATmega, and ATXmega families, and have experience with ARM, RISC-V, and AVR architectures.

With a strong foundation in Embedded C, C++, Python, debugging, and testing methodologies, I am passionate about optimizing performance and ensuring reliability in embedded systems while adhering to industry-standard coding practices such as MISRA-C.

Beyond firmware development, I have experience in hardware review, including schematics and PCB analysis, as well as hands-on expertise in automating test equipment such as oscilloscopes, power supplies, signal generators, etc.

UART-DMA Driver Demonstrates efficient UART communication using DMA. This implementation enables data transfer between the UART peripheral and memory buffers while bypassing the CPU for improved performance. Technologies: Embedded C, DMA, UART, Bare-Metal, MISRA-C, STM32F4.

ADXL345 Driver Implements an ADXL345 accelerometer driver. Utilizes reusable, modular SPI and DIO drivers to efficiently interface with the sensor, capturing precise acceleration measurements along the X, Y, and Z axes. Technologies: Embedded C, SPI, DIO, Bare-Metal, MISRA-C, STM32F4.

Reusable Peripheral Drivers Demonstrates reusable peripheral driver development, these are designed with modularity, scalability, and reusability in mind, allowing them to be updated to support different microcontroller families and vendors. Technologies: Embedded C, Peripheral Drivers, Bare-Metal, MISRA-C.
