Summary
🤩
Rockstar🎓
Top SchoolValérian Roche is a software engineer with five years of experience building and operating high-scale infrastructure for cloud-native platforms, currently contributing to Vercel's Compute team. He has led fabric control-plane and service-mesh efforts at Datadog, shaping service discovery, gateways, and internal networking for production systems. His background spans SRE and C++ platform development at Amadeus, where he focused on ultra-high availability, automation, and performance for hospitality systems. Valérian brings practical expertise in designing resilient control planes—demonstrated by contributions to the widely used envoyproxy/go-control-plane where he optimized caching, delta updates, and wildcard subscription logic. Based in Somerville, MA, he combines deep systems-level chops with hands-on operational experience across OpenShift, Kafka, Couchbase, and observability stacks. Colleagues describe him as a pragmatic engineer who improves robustness through targeted, test-driven enhancements rather than broad rewrites.
