PROFILE
Mikhail Chekalov
Over nine months, contributed to the Netcracker/pgskipper-operator repository by building and enhancing features focused on database reliability, security, and observability. Developed TLS support and credential verification for PostgreSQL, integrated backup monitoring with PgBackRest, and delivered new metrics for Grafana dashboards using Go and YAML. Improved deployment robustness through Helm chart updates, refined health probes, and enabled internal TLS for safer CI/CD testing. Addressed user management and password security, fixed core CRUD issues, and stabilized code quality with linting and workflow improvements. The work emphasized secure, maintainable backend development and proactive monitoring, leveraging Kubernetes, Prometheus, and containerization best practices.

Jun 1, 2026June 2026: Delivered container security hardening across Netcracker/pgskipper-operator, enforcing a read-only root filesystem, introducing a temporary mount path, and removing unnecessary security settings for specific operators. Added robot tests to validate hardening features and updated the testing library to support container hardening checks, enabling automated security validation. Implemented targeted fixes to maintain compatibility across operators (e.g., removing readOnlyRootFilesystem where needed and removing USER entries). Culminated in CI/test improvements ensuring security validation passes in automated pipelines. Commit activity highlights CPCAP-9409: hardening by skill, with subsequent test-lib updates and adjustments (a889364..., 69f46f5..., a6f9bfa...).
