Summary
🤩
Rockstar🎓
Top SchoolSean Madigan is a software engineer based in Bath, UK, with four years of hands-on experience in embedded systems and Bluetooth Low Energy (BLE) development. Currently at Nordic Semiconductor, he contributes to the nRF Connect SDK and Zephyr RTOS, implementing BLE controller features, HCI driver enhancements, and connection management improvements in widely used open-source projects. His background spans defence and semiconductor roles (BAE Systems, Infineon, DE&S), giving him a disciplined systems-engineering approach to firmware verification and real-world product constraints. A first-class MEng in Electrical and Electronics Engineering from Loughborough underpins his technical depth, while his frequent upstream contributions show an aptitude for collaborating in complex multi-vendor ecosystems. Notably, Sean’s work touches both low-level protocol details and practical sample apps, indicating he can bridge specification-level design and developer-facing deliverables.
