github ↗Colon cancer tissue analysis
8-class histopathology image classifier comparing a CNN built from scratch with MobileNetV2 transfer learning — about 88% accuracy vs. 85%, with the main STROMA/COMPLEX confusion documented.
github ↗Student performance early warning
Predicts students at risk of failing from the UCI dataset (1,044 students). Earlier grades removed to avoid leakage; Random Forest reached 78.7% accuracy (F1 0.88).

Need help with something? I take on data science, testing, and web work, and I am open to consultation — from a quick second opinion on a dataset to building out a full project. Questions about something I wrote are welcome too. I usually reply within a few hours.
