An automated web application security assessment tool built as the final-year project for my MSc in Computer Networking & Cyber Security at London Metropolitan University. Published to PyPI (v1.0.0) with 316 passing tests.
Scans 4 layers of a web stack — Application, Nginx/Apache, Docker, and Linux Host — with 24+ security checks mapped to OWASP Top 10. Integrates Anthropic AI API to generate tailored fix scripts automatically. Supports PDF reports with Day 1 / Day 7 / Day 30 remediation plans and tracks security posture drift between scans.
A production-grade REST API, admin SPA and static client site — all deployed and managed on a self-configured Ubuntu VPS. Covers the full DevOps lifecycle: DNS, SSL, Nginx reverse proxy, Gunicorn, systemd services, Redis, Celery workers and Firebase Firestore.
The admin dashboard is a React SPA featuring real-time analytics, visitor world map, blog CRUD with markdown editor, testimonial moderation, subscriber management and Celery-queued email notifications. The infrastructure handles 300+ daily visitors at 99.9% uptime.
A full e-commerce platform with product management, order processing and customer-facing storefront. Deployed on a production VPS with Nginx reverse proxy, SSL certificates and automated deployments.
Built to handle real transaction volume with a clean separation between the customer frontend and the backend API — focusing on infrastructure reliability, security hardening and ease of management.
