AI-Assisted Code Modernization with IBM
Junior Software Engineer · Software Engineering · September 2026
Based on a public IBM case study · not affiliated with IBM
Built and verified a full legacy-code modernization for KM-Waechter: corrected the service-wear math, handled missing readings safely, fixed the nightly report’s average and crash path, and caught a quiet mileage-conversion bug in the helpers. Also added a data-driven breakdown-risk analysis that follows the fleet history rather than the obvious but unsupported mileage/age assumption.

- Added the missing report test for a car with no reading and verified the repo with verify.py.
- Built analyze.py around the actual separating variables in the dataset instead of the tempting mileage/age assumption.
