Worked on the fedspendingtransparency/usaspending-api repository, focusing on backend development using Python. The primary contribution involved phasing out a legacy Databricks integration by removing the USE_DATABRICKS configuration setting, which streamlined the application’s data processing stack and marked a transition away from Databricks. This change simplified configuration management and reduced technical debt, making the backend codebase easier to maintain. The work required a clear understanding of the existing infrastructure and careful modification to ensure continued stability. No bug fixes were recorded during this period, and the main technical skills applied were Python programming and backend system refactoring within the repository.
