Summary

Senior🎓
Top SchoolArnaud Coston is a veteran network and Unix systems expert with over 20 years designing and hardening OpenSource Unix environments and L2/L3 datacenter architectures. He combines deep operational know-how in anti-DDoS, firewalls, WAFs, reverse proxies, PKI and Unix hardening with hands-on experience in virtualization, hypervisors and multi-supplier Ethernet/IP HA deployments. A reliable technical project manager and longtime freelancer, he also brings practical AWS and automation skills to bridge legacy on-premises infrastructure with cloud initiatives. His career spans public sector and fintech to professional services, reflecting an ability to secure and scale both regulated and high-availability platforms. Not obvious from titles: he thrives on low-level debugging and protocol-level audits—self-described as a "TCP/IP illustrated biggest fan"—which makes him particularly strong at incident investigation and architecture validation. Based in the Greater Paris area, he pairs advanced academic credentials with pragmatic delivery across long-term client engagements.
