I am a passionate software engineer with hands-on experience in designing and maintaining Java-based backend systems for large-scale financial applications. My expertise includes batch scheduling services that handle critical credit card operations such as payment adjustments, overdraft fee processing, and financial charge calculations. I have a strong understanding of implementing complex business logic, analyzing production issues, and delivering reliable, maintainable solutions in high-availability environments. In addition to backend development, I have experience in mobile application development using Android (Java), iOS, and Flutter. I contributed to overdraft charging logic for new wallet types, integrated custom FC charging logic for BNPL-enabled cards based on eligibility and billing criteria, and implemented code changes to evaluate eligibility rules and apply overdraft charges. I also worked on the FC Schedule service to apply charges to credit card balances not paid by the due date, ensuring accurate and reliable financial transactions in batch jobs.
