I'm an Embedded Software Engineer passionate about building reliable firmware and hardware solutions that solve real-world problems. My work sits at the intersection of embedded systems, electronics, and industrial automation, where I enjoy taking ideas from concept all the way to deployment.

Currently based in Hertfordshire, UK 🇬🇧, I work primarily with ESP32 and STM32 platforms, developing embedded applications in C/C++, designing PCBs, integrating sensors, and commissioning industrial control systems.
