Summary
🤩
Rockstar🎓
Top SchoolAngelo Failla is a Staff Site Reliability Engineer based in Dublin with over 25 years in infrastructure and operations, including a 14-year tenure at Meta where he led large-scale DHCP, PXEboot and OS provisioning overhauls. He blends hands‑on systems programming (Go, C++) with organisational leadership, having designed Meta’s dhcplb DHCP load balancer and driven an immutable image approach that cut provisioning from hours to minutes. Comfortable from incident commander to strategic influencer, Angelo has modernised data‑centre plumbing for IPv6‑only deployments and presented his work at industry forums. A long‑time internet veteran and open‑source contributor, he pairs deep technical craft with mentoring and cross‑functional stakeholder alignment, and outside work is an amateur photographer and long‑distance cyclist — a sign of persistence and attention to detail.
