PythonPower BIScikit-learn Azure CertifiedNeo4j Certified Google PM CertMSc Applied AI

I started my career maintaining the networks that keep millions of people connected. For 13 years at Ericsson and Huawei, I was the person who looked at the data when something was wrong, found the pattern nobody else had spotted, and turned it into a decision.

Then I went further. I completed an MSc in Applied AI at Aston University, building an Ensemble ML classifier across five models with 99.12% accuracy on 5 million records. I hold certifications from Microsoft, Neo4j, and Google.

Thirteen years of evidence. Three certifications. Two master's degrees. One consistent thread: turning data into something useful.

Featured ML Project — Cardiovascular Disease Detection

Ensemble Voting Classifier for Multi-Class CVD Detection

Built a soft-voting Ensemble Classifier combining five machine learning models to detect four cardiovascular conditions (Heart Attack, Heart Failure, Angina, and Peripheral Artery Disease) from structured patient data.

Dataset: 5 million synthetically generated patient records with 72 clinical features including ECG parameters, blood pressure, cholesterol, troponin, ejection fraction, and WBC count. 80/20 train/test split.

Self-managed from research question through data generation, model development, evaluation, and written submission. Deployed as a real-time patient prediction tool.

Ensemble Voting Classifier99.12%
Decision Tree85.03%
Random Forest79.08%
K-Nearest Neighbors68.52%

The Ensemble Voting Classifier combines the predicted probabilities of all five base classifiers using soft voting, aggregating their individual strengths to produce a more robust and generalisable prediction than any single model alone.

Evaluated via accuracy, precision, recall, F1-score, confusion matrix, calibration curves, and precision-recall curves across all four cardiovascular disease classes.
