Summary
🤩
Rockstar🎓
Top SchoolMinoas Galanakis is an Embedded Software Engineer based in Cambridge with eight years of experience building low-level, security-conscious firmware and libraries at Arm after starting his career at Plextek Consulting. He holds a B.Eng. in Electrical & Electronics Engineering and a Master’s in Embedded Systems from the University of Leeds, combining formal embedded systems training with practical product delivery. His open-source contributions to the widely used mbed TLS project show deep expertise in cryptographic primitives and Montgomery modular arithmetic, including lifecycle management of constants and secure zeroization. Comfortable navigating both algorithmic complexity and performance-constrained C code, he brings a pragmatic focus on correctness, security, and maintainability to embedded projects.
