Featured Projects

Cyber Revision: UK Cybersecurity Revision Platform

Free revision platform at cyber.jackghx.com, benchmarked against OWASP Top 10:2025, NIST CSF 2.0, and MITRE ATT&CK v19. Quizzes, spaced-repetition flashcards, auto-graded challenges, and a certificate verification system with real verification codes.

Scrub: Security-Artefact Sanitiser

Local-first tool that detects and pseudonymises infrastructure-specific secrets, internal IPs, MACs, cloud keys, tokens, connection strings, that generic PII tools aren't built to catch. General DLP tools are built for customer data; security practitioners leak a different class of identifier entirely, and Scrub is built specifically for that gap.

  • ~30+ entity types via a custom Presidio recogniser pack
  • FastAPI service, Next.js review UI, pipeable CLI, git pre-commit hook, and a CI workflow that gates on audit results
  • Consistent, reversible pseudonymisation: same input always maps to the same output, so sanitised data stays analytically useful
  • OCR redaction for images and screenshots planned

NeuralRevise: Autonomous MCQ Revision Agent

An autonomous web agent built with CDP + Ollama (llama3.1:8b) that automates MCQ revision tasks with adaptive memory. The agent navigates revision platforms, answers questions, and builds a self-updating memory of weak topics.
