Hi, my name is
Al William Tammsaar
Eternal tech optimist


Hey, I'm Al. I mostly go by the internet as "Rez" these days. I spend most of my time working on  Solid World  as Co-Founder and Head of Protocol.

I have a background in Computer Science, specialized in Human-Computer Interaction and Machine Learning. MSc Univestiy of Copenhagen. I'm obsessed with complexity and human behavior. This is what motivates me on a daily basis.

I've worked with small early-stage start-ups and considerable e-commerce solutions serving tens of thousands of people a day. I've served as a data scientist, consultant, designer, user-researcher, product manager and more. I enjoy deeply understanding whole domains. An overview of my work history is available on LinkedIn.


If you would like to get in contact, the best way to do that would be to add me on Linkedin or Facebook. I can always find time to go out for a cup of tea with you. :)
