In January 2026, Mark Cupac developed a SQLite-backed persistence layer for job state management in the tt-inference-server repository. He designed and implemented a database-driven job lifecycle, enabling job creation, cancellation, and result path retrieval to persist reliably across server restarts. Using Python, Mark refactored the backend to standardize field naming and integrated settings-driven database paths, while also updating and expanding unit tests to reflect the new schema. His work improved the reliability and recoverability of long-running inference jobs, enhanced observability, and streamlined troubleshooting, demonstrating depth in API development, backend engineering, and database management within a production environment.
January 2026: Delivered a SQLite-backed persistence layer for job state in the tt-inference-server, enabling durable job data across restarts and more robust cancellation handling. Implemented a DB-backed job lifecycle (create, cancel, get result_path), updated field naming to result_path, and wired tests and settings accordingly. The changes improve reliability, traceability, and recoverability of long-running inference jobs, with maintainability gains from refactors and CI-ready code.
