Alex

Hi! I’m Alex - sometimes going by the memorable name of 0x416c6578 online. I’m a (predominantly backend) software engineer working in finance, specifically payments (Open Banking).

I have interests in the Go programming language, algorithms, embedded / hardware hacking and in my free time I like to play board games, bouldering, running and badminton.
