Worked on the percona/pg_tde and percona/postgres repositories to enhance documentation, testing, and deployment reliability for PostgreSQL Transparent Data Encryption (TDE) extensions. Focused on improving onboarding by refining setup guides, clarifying key management details, and correcting service instructions, all documented in Markdown. Expanded test coverage using SQL and Makefile to validate extension version reporting and ensure accurate state tracking. Addressed system compatibility by delivering a Python 3.6 subprocess fix, improving deployment script reliability across RHEL, OL, and Rocky Linux environments. Demonstrated depth in database administration, Python scripting, and cross-version testing, contributing to more robust and maintainable enterprise deployments.
