Jan Mazajic contributed to the keboola/storage-api-php-client and storage-backend repositories, focusing on backend and API development using PHP, YAML, and Docker. Over six months, he delivered features such as configurable timezone handling for Snowflake exports, timestamp filtering enhancements, and the consolidation of data warehouse connectors onto Snowflake and BigQuery. Jan stabilized CI/CD pipelines with GitHub Actions, improved static analysis, and maintained backward compatibility by reverting breaking API changes. His work emphasized robust error handling, clear documentation, and test-driven development, resulting in more reliable data exports, streamlined onboarding, and a maintainable codebase aligned with evolving cloud data warehouse strategies.
February 2026 focused on strengthening Snowflake export reliability and data accuracy by making timezone handling configurable across CSV and Parquet exports, and by enabling per-export timezone in the PHP client API. Implemented session timezone management with robust cleanup, updated tests to reflect Snowflake capabilities, and added API support for timezone configuration. Business value: more accurate exports, consistent TIMESTAMP display, and reduced operational risk.

December 2025: End-of-life for legacy data warehouse connectors consolidated onto Snowflake and BigQuery, with a focused cleanup of environment variables and utilities to reduce configuration complexity and deployment surface area. The storage-backend stack is now narrower, more maintainable, and better aligned with cloud data warehouse strategies.

November 2025: Focused on stabilizing and delivering timestamp-related capabilities in keboola/storage-api-php-client. Restored timestampType support during table creation and enabled TIME_STRING-based filtering to improve API timestamp management and querying flexibility. Reinstated TIME_STRING filtering guidance in the API docs to ensure accurate and discoverable functionality. These efforts enhanced data querying capabilities, reduced onboarding friction, and strengthened platform reliability.
