Mathematics and cryptography

I teach mathematics in CPGE (undegraduate students) since 2015.

I enjoy playing CTF, you may check my CryptoHack profile

I am TOSA Python 3 certified with score 1000/1000.

I have also completed a consulting mission with CNES in Toulouse aimed at developing soft decoders of Reed-Solomon codes.
