Talenta-Receiver-API-Gateway is a backend service that acts as an API Gateway for orchestrating and managing API traffic between client applications and backend services (such as HRIS/Payroll systems) — particularly Talenta API integrations (Talenta by Mekari). It centralizes authentication, routing, business logic orchestration, and data flow with external systems like Talenta. This project was built as part of a real integration workflow where API calls are validated, handled, and data is persisted or forwarded to downstream services.
- RESTful API Development: Built robust APIs using .NET Core and SQL Server for seamless integration across web and mobile banking platforms.
- Transaction Reliability: Implemented backend service flows for fund transfers, prioritizing data validation and system stability under peak loads.
- Optimization: Refined SQL Server queries and backend logic to improve transaction processing speed and ensure low-latency experiences.
