AI-Assisted Code Modernization with IBM
Junior Software Engineer · Software Engineering · August 2026
Based on a public IBM case study · not affiliated with IBM
Built and verified a full legacy-code modernization for a fleet service tool: fixed the wear calculation, handled missing service readings safely, corrected the nightly report’s average and mileage conversion, and added the missing regression test. Also produced a data-driven breakdown-risk analysis that prioritizes km_since_service and driving intensity over the misleading mileage/age assumption, with documented verification in NOTES.md.

What stood out6
- Correctly identified the integer-division line as the cause of the near-worn car being reported as 0% worn.
- Caught the quiet helper-module mileage conversion bug that no test directly covered and fixed it in fleet_utils.py.
- Wrote a real acceptance check and a NOTES.md that explains what the agent missed and how the work was verified.
