Develop high-performance backend services using C# (.NET Core) and Java (Spring Boot). Build RESTful APIs and GraphQL endpoints for seamless communication between frontend and backend. Implement microservices-based architectures for logistics solutions. Ensure frontend-backend data consistency and performance optimization.
2. Logistics Systems Integration: Integrate applications with logistics and supply chain systems, including Warehouse Management Systems (WMS), Transportation Management Systems (TMS), and Enterprise Resource Planning (ERP) systems. Implement real-time tracking, shipment status updates, and automated workflows. Work with third-party APIs, web services (SOAP / REST), and EDI (Electronic Data Interchange). Handle data synchronization across distributed logistics platforms.
3. Backend Development & Cloud Services: Develop scalable, secure, and high-performance backend services using C# (.NET Core) and Java (Spring Boot, Hibernate, JPA).
