My name is Nikolai Konovalov, also you may know me as li0ard (pronounced Lizard). I'm cryptography engineer, OSS maintainer and eMRTD researcher.
I β€οΈ coffee, Linux, music, books and films.
Started by writing Discord and Telegram bots, now architect cryptography libraries, building eMRTD tools, and writing articles about my work.
