Over a three-month period, contributed to geoadmin/mf-chsdi3 and service-stac by modernizing OpenTrans API integration, enhancing database support for large files, and unifying time handling for transport data. Leveraged Python, Django, and SQL to refactor legacy code, implement BigIntegerFields for asset sizes, and standardize timestamp formatting using ISO 8601 parsing. Improved test infrastructure with requests-mock and expanded coverage for API and time-related logic, ensuring robust CI/CD workflows. Addressed configuration and migration issues, streamlined dependency management, and clarified documentation, resulting in more reliable deployments and maintainable codebases across both backend services and their supporting test environments.
January 2025: Delivered unified time handling for the OpenTrans API in geoadmin/mf-chsdi3, consolidating time-related changes, improving correctness and consistency of timestamp formats, and strengthening test coverage. Key improvements include refactoring format_time() to ISO 8601 parsing via dateutil.isoparse, explicit timezone handling for OJPStopEventRequests, standardization of UTC/Zulu terminology, correct treatment of timezone-naive timestamps as local time, and removal of unnecessary UTC defaults. This work enhances data integrity for departures and reduces downstream validation bugs.
