Project Overview: Understood existing code and database contents and created documentation. Acquired insurance industry knowledge, such as policyholders, insured persons, insurance types, products, and related regulations, and reflected this understanding in the code. Managed cloud platform environment deployment and debugging tasks (OCP, ELK). Analyzed, developed, and tested new requirements. For debugging existing programs, established unit tests and collected scenario data. Implementation: Worked on two systems using Spring 4 and Spring 5, with data access methods including MyBatis and ORM. The frontend utilized HTML and jQuery. Backend processes included native Java multithreading for computation and rule validation. Documentation: Conducted code reviews and created 20 operational flowcharts. Reviewed the database, rechecked 200 tables and stored procedures. Reviewed operational processes, established package workflows, and defined code in various Git environments. Debugging: Corrected code-related caching errors that caused data inaccuracies. Fixed cross-browser issues on web pages.
