About

I’m nisedo, a security engineer at Trail of Bits.

I used to stare at smart contracts until one of us broke. Now I throw agents (and an unreasonable number of tokens) at all kinds of software until something breaks.

My interest in hacking started long before I knew it could be a career. I got my first PC at six and started building my own computers at ten. As soon as I got into video games, I was exploring how cheats worked and eventually creating my own.

I set up and ran my own game servers, and jailbroke just about every console I could get my hands on, as well as the early iPhones (good old Cydia times). I was drawn to understanding how things worked and what else I could make them do.

I started my career in technology consulting in 2017, but eventually found my way back to my first love, hacking. I moved into blockchain security in 2023, starting with EVM smart contracts before expanding to other platforms, nodes, and broader systems.

These days, I spend my working hours (and most of my free time) figuring out how to make agents better at finding and fixing bugs, and helping developers build more secure software.

I also founded and lead Soliditors, a French-speaking Web3 security community with over 200 members.
