Business context
The project connected degree, self-study, and non-degree continuing education with online exams, live learning, academic operations, analytics, and the multi-role workflows across enrollment, teaching, graduation, and transactions.
Wensi Education
Turning multi-role education workflows and high-risk transactions into verifiable services.
I built on Java engineering while contributing to requirements, planning, payments, permissions, real-time interactions, customer communication, and agile delivery.
My role
I built Spring Cloud services and core business features while contributing to requirements, module decomposition, delivery planning, and customer alignment. The stack covered RESTful APIs, MySQL / Redis, RabbitMQ, Spring Security / JWT, WebSocket, payments, reconciliation, monitoring, agile delivery, and CI/CD.
