Worked on the octoenergy/xocto repository to deliver a feature enhancing local development workflows for S3FileStore. Developed an endpoint_url override, enabling compatibility with local S3 endpoints such as S3Mock, which improved both developer productivity and test reliability. The implementation involved aligning the _get_boto_bucket and _get_boto_client methods to support alternative S3 endpoints, facilitating smoother local testing and better parity with production environments. Utilized Python and boto3 to abstract S3 interactions and integrated local development tooling. No major bugs were addressed during this period, with the primary focus on backend development and improving continuous integration processes for the team.
