January 2026 consolidated report focusing on stabilizing TLS certificate expiry monitoring in azimuth-cloud/ansible-collection-azimuth-ops. Delivered a targeted bug fix to correct Prometheus alert label usage, ensuring the TLS expiry alert references an existing FQDN label and reduces false positives. The change, tracked under commit 90bc25b8942fd18dfc6888f5182359b71f6f95d0 related to issue #1101, improved alert accuracy, incident response effectiveness, and maintainability of the Ansible collection. Technologies demonstrated include Prometheus alerting rules (PrometheusRule), YAML configuration, and repository maintenance; demonstrated strengths in debugging, code hygiene, and cross-functional collaboration with monitoring and SRE teams. This aligns with business value by reducing alert noise, accelerating MTTR for TLS-related incidents, and improving reliability of hosted services.
