Summary
🤩
Rockstar🎓
Top SchoolArran Cudbard-bell is a seasoned network security engineer and Principal Architect of the FreeRADIUS project with 15 years of experience delivering robust, production-grade authentication and AAA systems. Based in Mexico City, he blends deep protocol-level expertise (RADIUS, EAP, UPnP/IGD) with pragmatic consulting for ISPs, switch vendors, and healthcare clients through his RM-RF practice. He has a proven track record of stabilizing and hardening core infrastructure—fixing time/sign, memory, and timeout issues in FreeRADIUS—and has contributed backend and full-stack improvements to widely used open-source projects like miniupnp and Gollum. Arran’s work spans hands-on development (including Python bindings and Lua/JIT components) to architectural guidance for large deployments such as Sky’s broadband platforms and campus-scale Eduroam rollouts. Known for combining rigorous QA and automated testing discipline from his HP tenure with an ability to direct small development teams, he brings both attention to low-level detail and practical product-minded leadership. A quirky self-styled “Chaotic Technology Opiner,” he often surfaces non-obvious operational fixes that prevent subtle failures in high-scale network environments.
