Global E-Commerce Optimization: Olist Case Study

60-hour end-to-end analysis on 100k+ orders from the Olist marketplace. Applied K-Means clustering to segment sellers into risk tiers, identified freight margin leakage, and built a delivery-delay satisfaction intelligence layer delivered as a Power BI executive dashboard.

Insight: Seller Risk Scoring Requires Both Dispatch Metrics and Customer Voice. NLP enrichment from review text adds a layer of early warning that SLA-only scoring cannot capture. Freight Leakage Lives in the Long Tail, Not the Average.

Telco Customer Churn Prediction

Predicting customer churn for a telecommunications provider using historical subscription and usage data. Logistic Regression and Random Forest models identify high-risk customer segments, enabling proactive retention campaigns before churn events occur.

Insight: Predicting Churn Requires Behavioral Signals, Not Just Demographics. The strongest predictors in telecommunications are behavioral aspects like contract tenure and service bundle counts.

Open University Learning Analytics

Cohort-level analysis of 32,593 student records from the Open University Learning Analytics Dataset (OULAD). Identifying engagement drop-off patterns, assessment submission behaviors, and predictors of student withdrawal to support early intervention strategies.

Insight: Non-submission is a withdrawal announcement — 92% of students who miss the first assessment deadline exit the course. VLE engagement diverges as early as week 3, giving a 6-week window to intervene before withdrawal becomes irreversible.
