Additionally, addressed data accuracy in user-facing shares by updating ListReceivedShares to exclude expired shares, thereby improving reliability and compliance with data retention policies. Demonstrated skills in backend development, cloud storage integration, and documentation, with a focus on maintainable code and collaborative development practices over a two-month period.
