Cybersecurity Analyst | Information Systems Graduate | Builder of Real-World Software Products

Sydney, Australia 🇦🇺

I'm completing a Master of Information Systems (Cyber Security specialisation) at Apex Australia Higher Education, Sydney.

My work sits at the intersection of:

• 🔐 Cybersecurity & incident response
• 🛡 Governance, risk & compliance
• 📊 Applied machine learning
• 🚀 Product engineering

I enjoy turning research, security frameworks, and technical ideas into practical systems with clear documentation and measurable outcomes.

Security research and case analysis covering:

• Optus data breach
• Medibank cyber attack
• Colonial Pipeline incident
• MOVEit vulnerability
• Latitude Financial breach

Mapped against:

• NIST Cybersecurity Framework
• ASD Essential Eight
• NIST Incident Response Lifecycle

Experience analysing:

• Privacy Act 1988 (Cth)
• Australian Notifiable Data Breaches Scheme
• GDPR
• ISO 27001
• APRA CPS 234

Building predictive and classification models using:

• Python
• scikit-learn
• pandas
• Orange Data Mining

Projects include:

• Phishing detection
• Customer churn prediction
• Credit risk modelling

I believe in building and shipping working systems — not only completing coursework.

MIS5320 Applied IS Project — a layered, AI-assisted phishing defence platform built as a team capstone project.

Key components:

• Phishing detection pipeline (TF-IDF feature extraction + Logistic Regression, SVM, Random Forest, XGBoost, Naive Bayes) benchmarked against peer-reviewed published research on an 82,000+ email corpus, with the SVM model reaching 99.16% F1, beating the published benchmark
• 5-fold cross-validation with statistical significance testing to validate results
• Risk-based awareness training module with adaptive scoring
• Governance dashboard and tamper-evident URL verification registry
• FastAPI deployment with automated testing and CI/CD

The project included structured literature analysis and evaluation against existing published research.
