Enterprise Java Automation System
Spring Boot microservices system for automating business-critical workflows — invoice processing, reconciliation, and reporting. Integrated with legacy ERP systems via REST and messaging queues.
The Challenge
What needed to be solved.
A mid-size enterprise was running 40+ business processes manually — invoice matching, payment reconciliation, compliance reporting, and vendor onboarding. Each process involved multiple spreadsheets, email chains, and approvals that took days to complete. The legacy ERP system had no modern API layer.
The Approach
How I built the solution.
Designed a microservices architecture using Spring Boot with Kafka for event-driven communication between services. Built REST and SOAP adapters to integrate with the legacy ERP without modifying it. Implemented idempotent processing pipelines for invoice matching and reconciliation, with PostgreSQL for audit trails. Deployed on Kubernetes with Helm charts for reproducible infrastructure.
