Worked on backend performance optimization for the openMF/fineract repository, focusing on the Loan COB processing workflow. Addressed system responsiveness by reducing the Spring Job poll interval from ten seconds to five hundred milliseconds, enabling more frequent partition step completion checks and improving overall loan COB throughput. The implementation leveraged Java and the Spring Framework, with careful documentation of the trade-off involving increased database load and recommendations for ongoing monitoring. No major bug fixes were completed during this period, but the feature delivered a targeted improvement to backend job scheduling, reflecting a pragmatic approach to balancing performance and resource utilization.
