Welcome to my portfolio! Explore my projects and experience in embedded systems, IoT, and firmware development.
I'm a Senior Embedded & Firmware Engineer with over ten years of experience designing innovative IoT solutions and embedded systems. From leading the development of Smart RTUs at Innovative Systems to delivering secure IoT gateways for Industrial Scientific and Aware360 at PowerSoft19, I specialize in embedded C/C++, Python, RTOS, Linux, and protocols like IEC 60870 and MQTT. My work spans the full product lifecycle, from bare-metal firmware to cloud-integrated web interfaces, with a focus on security and performance. I hold an M.Sc. in Electrical Engineering from UET Lahore and thrive on solving complex technical challenges. When I'm not coding, I enjoy diving into tech courses or hitting the trails for a hike.
