I'm a software engineer interested in infosec and systems software.

Education

MSc Computing Science at Utrecht University (2020-2023)

My Masters Thesis focused on the Parameterized Complexity of Defensive Alliances (a graph theory problem about finding subsets of a graph where the vertices have more neighbours in the subset than outside of it).

First Class Honours BSc Computer Science at Coventry University (2016-2020)

Thesis was on object detection in Satellite imagery, focused on the Sentinel 2 dataset.

Publications

• "Adapting SHELFs to make LKM-less Kernel Modules" in tmp.0ut #4
• "Misusing XDP to make a KV Store" in 'Paged Out! #5' (pg. 20)

Security

I have found security flaws in:

• GRUB2, which resulted in a bypass for UEFI Secure Boot.
• TP-Link EAP Access Points
• Terramaster NASs

Hackathons

I founded hack.athon.uk, a website dedicated to helping people get involved with the hackathon community and also to help organise them.

Throughout my undergraduate program, I attended over 20 Hackathons building projects like:

• Homebrew for the Vectrex
• Using RF interference to make music
• Internet Connected Trebuchet
• Dinorun controlled by Applause
• Snake as a UEFI Shell Command

I was one of the co-founders of CovHackSoc, Coventry Universities hackathon society, president from it's founding in 2017 until 2019.

I've been featured on Major League Hacking's 2020 list of Top 50 Hackers for "people who have stood out from the crowd and done something exceptional within the hacker community"

Organisational Roles

• Lead Organiser for CovHack 2019
• Tech Lead for CovHack2020
• Tech Lead for HackQuarantine

Travel

I've travelled to over 50 countries, doing things such as:

• Backpacking through Central Asia (Kazakhstan, Kyrgyzstan, Tajikistan and Uzbekistan), the Southern Caucasus (Azerbaijan, Georgia and Armenia), South East Asia (including Malaysian Borneo and Brunei) and Ghana.
• Doing a Internship based around remote sensing in Cape Town, South Africa
• Cultural Exchanges in Oslo (Norway), Helsinki (Finland) and Guangzhou (China)
