PROFILE

Hleb Rubanau

Worked on the konturio/disaster-ninja-cd and getappmap/appmap-intellij-plugin repositories, delivering features that improved deployment stability, database reliability, and CI/CD traceability. Focused on Kubernetes-based infrastructure, implementing Helm-driven changes for multi-environment deployments, PostgreSQL replica management, and stateless service design using YAML and Shell scripting. Addressed operational challenges by refining node scheduling, resource governance, and backup resilience, while also resolving storage and configuration issues to ensure reliable rollouts. Enhanced artifact traceability in CI/CD pipelines by updating GitHub Actions workflows to include commit metadata in build artifacts, supporting reproducibility and auditability across environments. Demonstrated disciplined, incremental delivery and robust infrastructure management.

Oct 1, 2025

In Oct 2025, the team delivered a key CI/CD improvement for getappmap/appmap-intellij-plugin by implementing CI Build Artifact Naming for Traceability, significantly enhancing artifact traceability and management across CI runs. The feature uses the GitHub run number and a truncated commit SHA to simplify auditing and rollback workflows, improving reproducibility across environments.

July 2025 monthly summary focusing on reliability, scalability, and backup resilience for disaster-ninja-cd. Key work concentrated on Event API DB replica management and primary leadership stabilization, plus a targeted backup timeout improvement in the test environment. The changes emphasize storage efficiency, high availability, and CI/CD reliability in production and testing. Highlights include cross-node replica rebalancing and migration to gpu01, node affinities and tolerations to ensure safe scheduling, and decommission-safe leadership stabilization on a closing node. Additionally, a backup resilience improvement was implemented by increasing the pgbackrest archive-timeout to 4 hours in the TEST-PG17 environment to prevent WAL archiving timeouts. Business value delivered: improved DB storage efficiency, reduced risk of replica contention during maintenance, smoother upgrades/decommissioning, and more reliable backups in the test environment, enabling faster iteration and lower operational risk.
