Problem
A large legacy estate (Visual Basic applications and Crystal Reports) needed to move to a modern Java stack, but nobody fully understood it and ad-hoc AI coding produced inconsistent results.
What I built
- A spec-driven workflow with a custom code-transformation agent and a multimodal report-migration agent, plus a CI feedback loop that let agents correct themselves.
- A GraphRAG code-intelligence platform over more than 1M code nodes, so engineers and agents could query the estate.
Outcome
- About 70% shorter modernization timeline, and 40% more efficient than unstructured AI coding.
- Code comprehension time down about 60%, with queries answered in under 1.5 seconds.
