PROFILE
Mattia
Worked on the cozystack/cozystack repository to deliver secure, multi-tenant SSH access to KubeVirt VMs, aligning RBAC rules for port forwarding and improving operational efficiency. Enhanced reliability in DNS and monitoring by correcting CoreDNS RBAC permissions and fixing PromQL syntax errors, reducing alert disruptions. Improved Keycloak deployment stability and NFS-backed storage reliability, focusing on deterministic health checks, robust multi-VM access, and migration safety. Addressed observability by fixing dashboard misconfigurations and refining per-port traffic controls. Leveraged Go, Kubernetes, and Prometheus, applying DevOps and backend development skills to strengthen security, observability, and data integrity across cloud infrastructure components.

Feb 1, 2026February 2026 monthly summary for cozystack/cozystack. This period focused on reliability and observability improvements in the DNS stack and monitoring alerts. Key deliverables reduced operational risk by aligning CoreDNS with Kubernetes RBAC and fixing a PromQL syntax error in CNPGClusterOffline alert, leading to more stable pod behavior and fewer alert-related disruptions. Technologies demonstrated include Kubernetes RBAC and ServiceAccounts, CoreDNS deployment via Helm charts, Prometheus/VMA (vmalert) query correctness, and solid Git-based change provenance.
