What Nikhil demonstrated

Built and verified an end-to-end fix for a legacy car-service system: corrected the wear calculation, handled missing service readings safely, repaired the nightly report, added the missing regression test, and preserved the 15,000 km / 80% business rules. Also produced a data-driven breakdown-risk analysis that follows the labelled fleet history rather than the tempting but unsupported mileage-and-age assumption.
