Hi, my name is
Al William Tammsaar
Eternal tech optimist


Hey, I'm Al. On the internet, I sometimes go by the name "Rez" as well. I currently spend most of my time working on  Soldera  along with my co-founder Stenver Jerkku. I'm also one of the authors behind the Solid World  protocol.

The main themes I focus on revolve around sustainability and finance. I want economic incentives to align with solving climate change. I have a background in Computer Science, specializing in Human-Computer Interaction and Data Science. I have an MSc from Univestiy of Copenhagen. I'm obsessed with complex systems and human behavior. I'm heavily motivated by learning new things.

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. :)
