PROFILE
Nenad Stevic
Over six months, contributed to the swisstopo/swissgeol-boreholes-suite by engineering robust deployment automation, security hardening, and feature delivery across cloud-native infrastructure. Leveraging C#, TypeScript, and Kubernetes, developed and maintained Helm-based deployment workflows, implemented secure secrets management, and improved CI/CD pipelines for reliable, auditable releases. Enhanced API throughput, authentication, and configuration validation while aligning analytics and release governance across environments. Addressed critical bugs in Kubernetes secrets handling and streamlined operational feedback loops with automated health checks and parallelized testing. The work enabled faster, safer production deployments, unified configuration management, and improved observability, supporting both backend and frontend development requirements.

15 Commits • 3 Features
Jun 1, 2026June 2026 focused on strengthening deployment reliability, achieving cross-environment configuration parity, and unifying analytics, while addressing a critical secrets-management bug. Key improvements include deployment workflow automation with explicit kubeconfig handling, clearer debugging steps, removal of unnecessary debug commands, and enabling scheduled production deployments by dropping the dry-run flag. Release and configuration alignment across environments ensures the latest features/fixes are consistently deployed via updated chart/config versions. Google Analytics IDs are now synchronized across production configurations for unified analytics. Major bug fixes addressed secure handling of Kubernetes secrets for database connection strings, preventing overwrites with blank values, adding nullable-field checks, and emitting warnings when fields are nullable. This reduces deployment risk and protects sensitive connection data across environments. Overall impact: more reliable, auditable deployments; consistent feature exposure across environments; stronger security and observability; and improved business insight from unified analytics. The team demonstrated strong Kubernetes/Helm expertise, robust secret management, and end-to-end CI/CD discipline, delivering tangible business value and faster, safer releases.

May 1, 2026May 2026 highlights for swisstopo/swissgeol-boreholes-suite focused on security, deployment reliability, and controlled feature exposure. Delivered Secure and Automated Deployment Workflows with dry-run simulations, secure token handling, and robust secrets management across AWS regions. Implemented Int-View Environment Authentication enhancements with a secret-driven pattern and safer fail-fast behavior when secrets are unavailable. Enabled Anonymous Boreholes View Access in integration and production to streamline external access. Hardened the codebase against env injection, aligned secret lookup patterns across environments, and ensured explicit secrets for security hotspots. These changes collectively improve deployment velocity, security posture, and external accessibility while maintaining strict governance of secrets and access.
