February 2025 — Delivered key test-infrastructure enhancements and stability fixes across Snowflake connectors to accelerate safe releases and improve cross-platform reliability. Key outcomes include a Wiremock-based test infrastructure for snowflake-connector-net with URL-property refinements and CI/CD readiness; removal of Windows-specific permission warnings in snowflake-connector-python; and test-suite stabilization by skipping a known-incompatible test until Snowflake 9.4. These changes reduce false positives, improve test isolation, and position the team for smoother upgrades to Snowflake 9.4, delivering higher-quality releases with faster feedback. Demonstrated skills in test infrastructure design, CI/CD integration, cross-language testing, and version-compatibility risk mitigation.
