Summary
🤩
Rockstar🎓
Top SchoolStefan Mavrodiev is an engineering manager with 11 years of experience leading software delivery and embedded systems development from Plovdiv, Bulgaria. He progressed through technical and delivery leadership roles at ScaleFocus, moving from principal engineer and delivery manager to his current engineering manager position. With a deep background in embedded Linux and IoT firmware from eight years at OLIMEX, he has hands-on expertise porting board support, fixing low-level hardware/EEPROM issues, and adapting boot and kernel configurations across ARM platforms. Stefan contributes to notable open-source projects like Armbian and OLINUXINO, where his patches enabled new board variants and improved hardware compatibility—work that requires both firmware debugging and system-level architecture knowledge. He pairs a Master’s in Electrical and Electronics Engineering with practical board bring-up experience, making him comfortable bridging hardware constraints and scalable software processes. Colleagues describe him as a pragmatic leader who still dives into kernel and u-boot patches when a tricky hardware bug threatens delivery.
