Gleb Rubanau engineered robust infrastructure and deployment solutions for the konturio/disaster-ninja-cd and getappmap/appmap-intellij-plugin repositories, focusing on reliability, scalability, and traceability. He delivered features such as multi-environment Helm-based deployment stabilization, PostgreSQL replica management, and CI build artifact naming, addressing production drift and improving database resilience. His technical approach leveraged Kubernetes, Infrastructure as Code, and GitHub Actions, with configuration managed in YAML and Shell. By implementing node affinities, resource governance, and disciplined CI/CD workflows, Gleb reduced operational risk and improved auditability. His work demonstrated depth in DevOps practices, database administration, and infrastructure management across complex distributed systems.

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.
