Nenad Stevic developed and hardened the deployment and observability stack for the swisstopo/swissgeol-boreholes-suite repository over two months, delivering 17 features and resolving 18 bugs. He implemented Helm-based deployment automation, introduced health check endpoints, and enforced configuration validation using YAML and JSON Schema. His work included security improvements such as removing automount service account tokens and setting resource defaults, as well as enhancing CI/CD pipelines with GitHub Actions. By focusing on API development, Kubernetes orchestration, and documentation, Nenad improved release reliability, operational transparency, and maintainability, demonstrating depth in backend engineering and cloud infrastructure management throughout the project.
February 2026 for swisstopo/swissgeol-boreholes-suite focused on security hardening, configuration quality, and release reliability. Implemented security hardening by removing automount SA token and setting default storage resource requests; improved developer experience and stability via linting and YAML defaults; strengthened CI/CD and release pipelines with action versioning, major-tag logic for releases, and packaging safeguards; added rigorous values.yaml validation and null handling to catch misconfigurations early; upgraded data extraction and enhanced healthchecks, chart/version management, and release documentation to improve observability and governance. Result: reduced risk, faster and more predictable releases, better quality gates, and improved maintainability.

January 2026 focused on delivering a production-ready deployment and observability stack for the SwissGeol Boreholes suite. Implemented Helm-based deployment with automated release detection, linting, and chart quality controls; added health checks including a new client health endpoint and dataextraction health endpoint usage; hardened deployments with resource defaults, security settings, and configuration/secret checksum annotations. The work enables faster, safer releases, improved reliability, and clearer operational guidelines for production usage.
