Dimitrios Karnikis

I am an Embedded software developer at Bang & Olufsen interested in embedded devices, security, and the runtimes of programming languages. I have extensive knowledge in Bluetooth, micro-controllers, Trusted Execution Environments (TEEs), and shell scripting.
Currently developing a 2d roguelike exploration game based on Lua and Love2d.
