Reducing Churn in E-Commerce: My End-to-End Capstone Project in Predictive Modeling

Customer churn isn’t just a marketing problem - it’s a business survival issue. In competitive industries like e-commerce, losing one customer often means losing several revenue streams, especially when one account can represent multiple users. This post is a breakdown of my churn prediction capstone project for the postgraduate data science program at UT Austin - also tied to my master’s in data science at Deakin U. The project was closed-source, so I can’t release the full notebook, but I’ll walk you through everything I did including code snippets, results, charts, what I learned, and where this project fits in my larger journey into machine learning and MLOps. ...

Day 5–8: Fine-Tuning AI Models, Learning MLOps, and Structuring My Year of Projects

It’s been a few days since I posted an update here. Not because I wasn’t learning - in fact, the opposite. I was working through a mix of things, from structuring my year-long learning roadmap to actually fine-tuning large language models for the first time. Why I Wasn’t Posting Daily Simple: I needed to zoom out a bit. I took a couple of days to sketch out what I want to build in the next few months — not just random toy apps, but meaningful projects that actually challenge me to grow. ...
