Dimitris Sotirakis is a Staff Software Engineer with 10 years of experience specializing in platform, release and backend engineering, currently shaping cloud-first platform work at Grafana Labs. He has driven significant CI/CD improvements—cutting build times, decoupling OSS and enterprise pipelines, introducing Docker-per-PR workflows, and reducing flaky tests using observability tooling. His backend contributions to the widely used open-source Grafana include migrating datasources to dataframes, refactoring annotation queries, and fixing integrations like InfluxDB, demonstrating both product impact and deep engineering craft. He pairs strong Java and Go-centric backend skills with practical cloud and container expertise (Kubernetes, Argo, Drone, GitHub Actions) and a solid grounding in data-driven features. Notably, he built internal observability (Plugin CI report gRPC service) to surface CI metrics, showing a habit of instrumenting systems he operates. Based in Thessaloniki, Greece, he blends research-minded problem solving from his engineering education with hands-on reliability and release ownership.
