Summary
🤩
Rockstar🎓
Top SchoolCallum Leslie is an Embedded Software Engineer and MSci Computer Science student at the University of Nottingham with a decade of hands-on experience across embedded C++, systems integration, and electrical design. He currently develops sensor-driven embedded applications at AG Products, where he built an automated data collection system of 50,000+ datapoints, designed a test platform for electric machinery, and integrated embedded systems with ML/CV pipelines. Comfortable across low-level stacks—CANBus, I2C, Modbus—he also uses Rust, WebAssembly, Protobuf and websockets to bridge embedded and web systems for performance-critical solutions. On GitHub he contributes full-stack improvements to utility projects like a Reddit video-maker bot, focusing on UX, robustness and code clarity rather than flashy public repos. Fast to learn and pragmatic, he has repeatedly reduced costs and manual effort through careful component selection and automation. Based in Middlewich, UK, he blends hardware-aware engineering with a keen interest in optimization and maintainable low-level software.
