Worked on atlanhq/application-sdk to deliver two core features over two months, focusing on backend development and data engineering using Python and SQL. Enhanced the BaseHandler interface by enforcing abstract methods for authentication, preflight checks, and metadata retrieval, ensuring derived handlers implement essential logic and reducing runtime errors. Developed scalable Parquet output capabilities by integrating Daft configuration, enabling automatic file splitting by target size for efficient storage and processing of large DataFrames. Refactored the ParquetOutput API for streamlined configuration and updated tests to validate new behaviors, improving reliability and maintainability across file handling and object storage workflows.

August 2025: Key feature delivered in atlanhq/application-sdk to strengthen handler contract and reduce future defects. Implemented BaseHandler interface enforcement by introducing abstract methods test_auth, preflight_check, and fetch_metadata that raise NotImplementedError in the base class, ensuring derived handlers provide concrete implementations. This improves reliability of authentication, preflight validation, and metadata retrieval across the extension points and plugin ecosystem, lowering runtime errors and accelerating safe integration of new handlers. Commit c7c193753cf9d430dfbeee9553f7832ca74a8976 (feat: implement abstract methods in BaseHandler).
