Henri Rantanen

This is a profile of Henri Rantanen, professional goofball, electronics engineer, photographer, programmer, space-time observer, and a coffee consumer. Inventor type of guy with a habit of optimizing everything. Also known online with my screen name Nerdaxic.

I am calm and well-mannered, logical, quiet, creative and lazy in a good way.

Founder, entrepreneur, accountant, developer, cleaning lady, secretary and trainee at Argnode Ltd.


I mostly spend my free time with technology or handicrafts. Digital media being the biggest time-suck. I’m often found building gadgets, programming stuff or tinkering with something.

Henri Rantanen, aka. nerdaxic

I try to use the screen name nerdaxic on online interactions where possible. Henri Rantanen is quite long and boring, so a short, unique, descriptive and difficult-to-pronounce nickname makes me easy to find across multiple sites and services.

The name originated from an online random nickname generator tool, me being a nerd and word being an adjective. It is different enough not already taken and as an added bonus, it sounds like some sort of medicine.
