Profile
Cybersecurity professional with hands-on experience in web application security, penetration testing, vulnerability research, reverse engineering, digital forensics, and AI/LLM security. Experienced in practical security testing, CTF-based research, Linux, offensive security tooling, and technical documentation. Comfortable on Linux, happiest with a target in front of me and a terminal open.

Technical Skills
Finding and exploiting flaws in web applications and APIs — injection, access control, authentication and session handling.
Regular CTF player across web, forensics and reversing categories, and the source of most of what I write up.
Reading binaries and stripped logic to work out what a program really does, and where it can be pushed off the rails.
Pulling evidence out of disk images, memory captures and traffic dumps, and reconstructing what happened from it.
Daily driver, Arch. Comfortable in the shell, with systemd, networking, and packaging things that were not meant to be packaged.
Scripting and tooling to automate the boring half of an assessment, plus the odd web project.
Security testing of LLM applications, including prompt injection, jailbreaks, adversarial inputs, RAG security, and LLM application vulnerabilities. Completed TCM Security's Introduction to AI 100 and AI Hacking 101.
Projects
- Custom Kali NetHunter-enabled Android kernel built for the Poco M3 (citrus), integrating NetHunter patches into the stock kernel source.
- Adds kernel-level support for wireless packet injection and external USB/HID tooling used in mobile penetration testing.
- Personal site and writeup archive, built with Zola and deployed from GitHub.
- Hosts CTF writeups and notes, all authored through a CMS.
- Secbook: a shelf of security papers, cheat sheets and references, readable in-browser or as a copy.
