Point-of-Sale Transaction Orchestration (NEMO)

Problem

A legacy system handling card transactions at point-of-sale needed replacing with an orchestration layer that could route every request through a single, rules-driven workflow decision point.

My contribution

• Built and maintained the request/response orchestration flow — every request passes through this layer, which decides the workflow to execute based on conditions and business rules.
• Worked across analysis, design, development, customization and implementation.
• Handled analysis, troubleshooting, bug fixing, testing and deployment for production issues.
