• Oversaw LifeAsia (AS/400 and COBOL/400) data migration following FWD’s acquisition of MetLife Hong Kong, covering 100% of the initial requirements raised by users of the former system.

Wiseman AI assisted legacy analysis initiative

Wiseman is an AI engineering assistant built on GitHub Copilot Enterprise to support understanding, analysis and maintenance of IBM i insurance systems.

In use: technical Q&A and reusable knowledge held in Markdown notes, issues and CSV indexes. Defined investigation workflows cover Jira ticket pre-study, COBOL, CL, SQL, DDS and stored procedures, business-rule tracing, data flow and caller/callee dependencies. Established agent rules cover coding standards, source-file and line-number evidence, and instructions against changing protected repositories. These are instruction-level controls, not a claim of enforced read-only permissions. A five-layer study model structures requirements, business processes, technical components, testing impact and historical alternatives. Planned capabilities include independent review and auto-fix quality gates, historical Jira mining, knowledge validation, revision tracking and a separate business-facing assistant. Automated execution, production deployment and measured efficiency gains are not claimed.
