P. Alemette Sivanarayana developed a feature for the bcgov/ECC-OFM-D365 repository that redefined how date windows and fiscal year alignment are handled for allowance payments and invoices. Using C# and leveraging backend and API development skills, they replaced a last-month check with a centralized 45-day eligibility window, introducing a helper to streamline date logic. Their work aligned fiscal year determination with payment dates, improving the accuracy of retroactive payments and invoice dating. While no bugs were fixed during this period, the changes laid a solid foundation for consistent invoice processing and enhanced the maintainability of date and time manipulation logic.
