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 a fleet service tool: fixed the wear calculation, handled missing service readings safely, corrected the nightly report’s average and crash path, and repaired a hidden mileage-conversion bug in shared helpers. Also added the missing regression test, produced a data-driven breakdown-risk analysis, and documented the agent review process in NOTES.md after running the project’s acceptance checks to completion.

What stood out6
- Caught the hidden fleet_utils.km_to_miles conversion bug that no test directly covered
- Verified the fix with an explicit before/after mileage check and a full 11/11 acceptance run
- Wrote a sensible breakdown-risk analysis that follows the data instead of the misleading mileage assumption
- Documented the agent’s mistakes and the verification steps in clear, employer-readable NOTES.md
- Leakage-Free Bug Diagnosis
- Directed AI Code Review
