Rockstar🎓
Top SchoolCristian Falcas is a Staff/Principal platform engineer with 16 years of experience designing and operating large-scale build, test, and deployment systems, currently building multi-cloud and hybrid infrastructure from Dublin. He specializes in Bazel-driven developer platforms and SRE practices, having been the primary Bazel owner at Etsy where he enabled sub-2-minute CI feedback across a 3M+ LOC polyglot monorepo and supported hundreds of engineers. Beyond build systems, he brings deep production reliability expertise—SLO/SLI design, peak-event operations, GCP/Kubernetes/Terraform automation—and a strong focus on developer experience and long-term maintainability. Active in open-source build tooling and platform automation (including contributions to distroless and Puppet modules), he pairs hands-on engineering with mentoring and cross-team technical leadership. Notably, he introduced hermetic, language-agnostic CI at scale and integrated tracing and observability across critical services, demonstrating both breadth and operational depth.
