Senior🎓
Top SchoolChenjun Shen is a Senior Expert DevSecOps engineer based in Munich with 18+ years of hands-on Linux and AWS operations experience and a formal background in software engineering. He blends deep PostgreSQL DBA skills—replication, partitioning, PgBouncer and PgBadger—with platform-scale cloud work, having migrated and hosted multiple Vodafone properties on AWS. His career spans OpenStack production deployments at massive scale (30k vCPUs, 1.5PB CEPH), CI/CD automation, and building bespoke monitoring/logging pipelines using syslog-ng, Logstash, statsd and Graphite. An active open-source enthusiast, he has contributed to well-known tooling like statsd/logster and frequently implements pragmatic integrations rather than boutique solutions. Colleagues rely on him for performance troubleshooting, incident postmortems and bridging development with operations across multi-cloud environments. Notably, he pairs deep low-level systems expertise with a history of shipping customer-facing platform migrations and long-lived automation.
