I've delivered payment, reconciliation, financial, and AI intelligent systems for Qingu Technology, Huifu Payment, Beijing JY United Information Technology, and Gome Financial Holding Group.
At Qingu Technology, I lead legacy-system refactoring, redesign system architecture and database schemas, and develop backend and frontend modules for AI, financial supply chain, and messaging-center products. I also coordinate product and QA teams through development, testing, and deployment while guiding engineers and reviewing code.
My work includes payment and collection services, reconciliation systems, credit reporting, transaction processing, and third-party payment and credit-platform integrations.
Across 14 years of software development, I've worked with Java technologies including Spring, Spring Boot, Spring Cloud, MyBatis, Redis, RabbitMQ, MySQL, Oracle, Vue, and React, while resolving production issues and mentoring junior engineers.
