CIO by day, cybersecurity professor & Forbes Contributor by night, and a firm believer that the best ideas start with good coffee. I’m passionate about using AI, cloud tech, and leveraging system dynamics to make work (and life) a little easier.
Outside of work, I’m either reading/writing in some indie coffee house, hiking shady trails along the river, or adding to my ever-growing collection of houseplants.
I’m always learning, always leading, and always up for a good book or a new coffee house to explore.

Neckbeard, but I am unable to grow a beard.

I'm a polish software engineer by trade (and passion) working on #Ruby on Rails in a SASS. But my true heartbeat is the #foss #RetroComputing rhythm: I love my #emacs #freebsd combo. I am very much into #smallweb and all that it stands for.

I love good #SciFi but recently I've been reading good #fantasy - which is a shock to me. There are great fantasy books out there!

Piracy is the only answer to streaming services.

Currently I am learning how to make a game for #commodore64.
