I enjoy participating in--and occasionally creating--Capture The Flag events (the cybersecurity kind). Challenges found in such competitions are often the kind of puzzles I really enjoy solving: taking apart a complex binary or program, figuring out how it works, finding ways to make it behave differently.
I posted write-ups for various challenges I solved on the EmpireCTF repository.
After the undergrad university team EmpireCTF, I joined the UK team cr0wn, which later became part of the Organisers superteam.
