Machine Learning for Automotive

AI / ML · August 2026

88/ 100

A ProoV case study · educational project, not employment

Built an end-to-end used-car pricing analysis for VW and Audi listings in the UK market. The work combined exploratory analysis, data cleaning, feature engineering, and model comparison, then translated the results into a CPO pricing recommendation. It showed strong practical judgment by using Random Forest as the preferred model and explaining the business impact in terms leadership could act on.

What stood out6
  • Combined VW and Audi listings correctly and used brand-aware EDA to surface the premium gap between the two marques.
  • Identified and removed clearly invalid rows such as zero-engine-size and extreme price outliers before modeling.
  • Compared Linear Regression and Random Forest using R², MAE, and RMSE, and reported a substantial improvement for the tree model.
  • Connected model output to CPO decision-making by estimating pricing exposure and recommending a practical deployment path.
  • Leakage-Free Feature Engineering
  • Comparative Model Evaluation

Energy and Renewable: Machine Learning for the Power Grid

Junior Machine Learning Engineer · AI / ML · August 2026

84/ 100

A ProoV case study · educational project, not employment

Built a TEY prediction model for gas-turbine operations using leakage-free sensor features and a time-based held-out evaluation. Compared a LinearRegression baseline with a RandomForest model, reported honest MAE/RMSE/R² on unseen data, and documented the model’s intended use, limitations, and monitoring plan in a concise model card.

  • Write the Model Card (clarity + honesty)25%
  • Explain it to a non-expert15%

Passed · pass mark 60/100

What stood out6
  • Correctly dropped CO and NOx because they are measured downstream of the prediction moment
  • Compared a linear baseline against a tree ensemble and showed a meaningful MAE improvement
  • Reported held-out MAE, RMSE, and R² and included a residual summary instead of relying on a single flattering metric
  • Wrote a model card that states intended use, limitations, and a concrete monitoring plan
  • Leakage-Free Feature Selection
  • Held-Out Model Evaluation

AI-Assisted Code Modernization with IBM

Junior Software Engineer · Software Engineering · August 2026

96/ 100

Based on a public IBM case study · not affiliated with IBM

Built and verified a full legacy-service repair: fixed the wear calculation with true division, handled missing service readings safely, corrected the fleet report’s crash and average, and preserved the 15,000 km / 80% business rules. Also added the missing regression test, documented the agent’s mistakes in NOTES.md, and delivered a data-driven breakdown-risk analysis that ranks cars by the factors the dataset actually supports.

  • Direct and audit the AI agent25%
  • Explain it like an engineer20%

Passed · pass mark 60/100

What stood out6
  • Correctly identified the floor-division bug and explained why it suppressed a nearly-worn car to 0%
  • Caught the agent’s planted mistakes, including the stray syntax-breaking character and the threshold change
  • Wrote a concrete acceptance checklist and used verify.py plus pytest to confirm the fix
  • Produced an analysis that explicitly rejects the misleading mileage/age assumption and ranks risk from the real predictors
  • Leakage-Free Bug Diagnosis
  • Verified AI Output Auditing
