Summary
👤
Senior🎓
Top SchoolXavier León is an engineering manager in Barcelona with 11+ years building and operating distributed systems, from core virtual networking to developer platforms and CI/CD orchestration. He blends deep technical craft—shipping backend and full‑stack contributions to notable open-source Spinnaker components around AWS CloudFormation—with product-minded leadership that reduces complexity while preserving developer productivity. At Adevinta he led modernization of internal CI/CD and designed an orchestration layer for deploying microservices across multiple Kubernetes clusters, tackling gaps the ecosystem hadn’t solved. A former researcher and PhD candidate, he brings a methodical, systems‑level view and a taste for pragmatic simplification (including replacing heavyweight infrastructure like Cassandra when it was overkill). He enjoys mentoring engineers and credits a few production outages as key learning experiences that shaped his reliability-first approach.
