Maker · YouTuber · Software developer
I build things, film the process, and write software that works.
I’m Robert Harmaakivi. On YouTube I share workshop builds and electronics projects. Through my company Gristone, I build web apps, integrations and tools for businesses.

Have a problem that software could solve?
I take on a small number of projects at a time, so you work directly with the person writing the code. Tell me what you’re trying to do and I’ll tell you honestly whether I’m the right fit.
