Simon Robin

Information Security Addict

Welcome, dear reader!

I'm Simon Robin a.k.a. sljrobin. I'm another Information Security enthusiast. I like learning and understanding what's going on under the hood in the digital world around us. I mainly enjoy Web Security, starting with CTF challenges back in university and moving on to doing it with my daily job.

I currently work as a Security Consultant, mainly to break things and help people fixing them.

I was born in Bordeaux, France. I've studied Computer Science at the French Engineering school ESIEA and Information Security at Royal Holloway, University of London and Imperial College London.
