CenterFlow ERP – Educational Center Management System

• Built a backend-only ERP platform using six Spring Boot microservices for identity, academic operations, student enrollment, finance, notifications, and API gateway routing.

• Implemented JWT authentication, role-based authorization, API Gateway token validation, protected internal endpoints, and database-per-service isolation using PostgreSQL and Flyway.

• Developed workflows for branches, classrooms, courses, batches, attendance, students, enrollments, pricing plans, installments, payments, refunds, expenses, instructor earnings, and reports.

• Implemented cross-service enrollment activation after the required initial payment using internal REST APIs, application events, and after-commit processing, supported by automated and end-to-end testing.
