## Writing
- [Why I picked the clustering model with the lower score](https://www.sangamgupta.in/writing/why-i-picked-the-clustering-model-with-the-lower-score): DBSCAN beat K-Means on silhouette score in my customer segmentation project. It also put 98% of customers in one group. Here's how I chose.
- [A portfolio that updates itself](https://www.sangamgupta.in/writing/a-portfolio-that-updates-itself): My old site went stale every time I shipped something. So I rebuilt it to read from GitHub instead of from me.
- [How I stop an AI from inventing achievements](https://www.sangamgupta.in/writing/how-i-stop-an-ai-from-inventing-achievements): ProfilePilot rewrites people's professional profiles. The hard part wasn't making the writing good. It was making sure it never claims something the person didn't do.
- [Why my credit risk model uses a 15% threshold](https://www.sangamgupta.in/writing/why-my-credit-risk-model-uses-a-15-percent-threshold): 85% accuracy sounded great until I asked what the model was actually catching. Moving one number changed what the model is for.
