Summary
👤
Senior🎓
Top SchoolBertrand Jacquin is a Senior System Development Engineer with 12 years in payments security at Amazon, bringing deep operational expertise in proxies, DNS, LAMP stacks, and large-scale server architectures. He progressed through hands-on roles from systems engineer to senior SDE within Amazon’s Payments Security organization, combining incident response, automation, and secure system design. Prior to Amazon he built network and monitoring platforms, performed security audits, and delivered high-availability, L2/L3/L7 filtering solutions for web infrastructure at Exosec and other firms. Trained with dual master’s degrees in System/Network & Security Engineering and Telecom/Network Engineering, he blends academic rigor with practical deployment experience on GNU/Linux, Solaris and HP‑UX. Based in Dublin, Bertrand is as comfortable writing Bash and proxy rules as he is architecting resilient payment services, and he often surfaces subtle operational risks before they become outages.
