Projects I'm proud of

NLP + Machine Learning

Amazon Review Sentiment Classifier

Python · scikit-learn · TF-IDF · DistilBERT · FastAPI · Streamlit · NLTK · pandas

Built and deployed an NLP classifier on 20,000 Amazon Fine Food Reviews, achieving 91% accuracy and 0.954 ROC-AUC with TF-IDF, Logistic Regression, class-balanced training, and GridSearchCV optimisation.

Benchmarked against a DistilBERT baseline, built FastAPI and Streamlit inference flows, and documented error-analysis findings around sarcasm, short reviews, and class-level F1 performance.

Pharmacovigilance Analytics

FDA FAERS Signal Detection

Python · pandas · Plotly · Streamlit · SQL · SciPy · PRR

Analysed 528,000 FDA FAERS adverse-event records from 2015–2025 and applied Proportional Reporting Ratio methodology to identify 8,920 disproportionate drug-reaction signals, including 1,403 high-priority pairs.

Built a reproducible pipeline from raw CSVs to a 218,977-report serious-event subset, then developed a Streamlit dashboard with dynamic Plotly views.

E-commerce Analytics

E-commerce Sales Analysis - Olist

Python · DuckDB · pandas · XGBoost · SHAP · Streamlit · Plotly

Built an end-to-end analytics project on 99,441 Brazilian e-commerce orders, joining 9 Olist datasets into a DuckDB star schema and engineering RFM, delivery, payment, review, and purchase-behaviour features.

Developed customer segmentation, churn prediction, and 12-month CLV modelling, then shipped a Streamlit dashboard with segment explorer, churn-risk, CLV, and business-summary views.
