Multi-store Retail Chain
A cloud-based POS and retail chain management platform supporting store operations including ordering, billing, inventory, discount management, and data synchronization across Headquarters and individual store nodes.
Key Contributions
- Resolved a long-standing data sync bug where incorrect map data sources caused batch jobs to always evaluate as incomplete, restoring reliable sync behavior between Headquarter and Store nodes.
What I Did
- Investigated and resolved business logic bugs in billing, discount, and payment source handling within the legacy calculation system.
- Fixed a critical batch sync bug where incorrect data sources caused Headquarter-to-Store sync jobs to perpetually report as incomplete.
- Performed production database operations (store setup, order corrections, discount/payment fixes) with formal deployment and rollback plans.
- Worked across a multi-language backend stack to deliver fixes and operational tasks.
