Top 1% proof-of-work portfolio 🎯 TURN ONE COMPETITION INTO A PORTFOLIO PROJECT Do not upload only your final score. Create a GitHub repo with: 1. Problem statement • What are you predicting or optimizing? 2. Dataset • Source, size, target variable, and license 3. Approach • Baseline model • Feature engineering • Model comparison • Validation strategy 4. Results • Final score, metric, and leaderboard rank 5. Code • Clean notebooks or scripts • requirements.txt • Reproducible setup 6. Learnings • What worked, what failed, and why Example: “Built a baseline logistic regression, then improved validation and feature handling. Final AUC: 0.86. Learned that leakage in the validation split was the main issue.” Recruiters value evidence that you can explain your approach, show clean code, and avoid copying public solutions without understanding them. Weekly action ✅ This week: 1. Join one beginner competition. 2. Build a simple baseline model. 3. Make one valid submission. 4. Push your notebook to GitHub. 5. Write a 5-line results summary. 📌 Rule: A clear, reproducible project with an honest explanation beats an unexplained high leaderboard score.
