What Sumbal demonstrated
Built and verified a full legacy-code modernization for KM-Waechter: fixed the wear calculation, handled missing service readings safely, repaired the nightly report, corrected a hidden mileage-conversion bug in the helpers, and added the missing regression test. Also delivered a data-driven breakdown-risk analysis that ranks cars by service-history and usage signals, with clear acceptance checks and written audit notes.
