Lery

I've firstly graduated in mathematics and later in information security. I'm working on crypto designs, attacks and countermeasures for different customers, both in hardware (mostly smartcards, and more recently IoT) and in software (mostly in Go, C and Python).

For fun, I like to do CTF games.
