• Participated in ABS (Asia Business System) projects as a system designer. Communicate across multiple teams to analyze system requirements and design a microservice architecture running on Red Hat OCP. This project integrated the accounting servers of 10 overseas branches (Singapore, Hong Kong, Cambodia, etc.) and reduced server costs by 80%. • Provided solutions and collaborated with the team to implement solutions. Cross-team communication to discuss the handling of data flow. • Helped less-experienced members and improved code quality through code review. • Maintaining the ABS system, handling system problems immediately and improving the system to improve user experience. • Developed the frontend using VUE and the backend using Spring Boot and designed and normalized databases and tables.

• Participated in CBP (Core Banking Project) projects as a developer and developed RESTful APIs using Spring Boot. This project decouples monolithic servers into microservices, reducing 80% of server costs. • Developed batch programs using spring boot and PL/SQL and tuned the performance so that the system could process 7 million pieces of customer data within the daily time limit. • Finding database execution performance bottlenecks and performing tuning. I tuned stored procedures that need to run for six hours to less than one hour. • Identify system problems in time and propose solutions and implementation. • Tested code to ensure that the program meets the system requirements.
