Stathis Fotinos engineered robust Helm chart enhancements and backend integrations across the grafana/helm-charts and grafana/pyroscope repositories, focusing on deployment stability and automation. He introduced PodDisruptionBudget controls, custom labeling, and ingress automation to streamline Kubernetes operations, leveraging Helm, Kubernetes, and YAML for configuration management. In the lichess-org/berserk repository, he expanded Python API coverage with new endpoints and type-safe data modeling, ensuring maintainable code through comprehensive testing and documentation. Stathis also automated Docker image builds for Aryakoste/mattermost using GitHub Actions and Docker, improving CI/CD reliability. His work demonstrated depth in DevOps, chart management, and backend development for scalable systems.

September 2025: Delivered key Helm chart enhancements for Pyroscope to improve ingress automation and DNS management, enabling external DNS integration and customizable ingress resources. Upgraded the chart to 1.15.0 and extended values.yaml and the ingress template to support external DNS services. Consolidated configuration to reduce manual steps and improve deployment consistency across environments. This work provides clearer deployment patterns for multi-tenant setups and aligns with ops-focused automation.
