About
My name is Raivo and I am a full-time freelance developer from Estonia. I have 15 years of experience in software development and I hold a Masters degree in Computer Science. (more info)
I like to create custom web applications. My development platforms are Node.js and SWI-Prolog on the server side and KnockoutJS and Bootstrap on the browser side.
I am also a maintainer of the Blog-Core blogging framework and
a number of SWI-Prolog packs.
I'm available for hire as a freelancer.
I can also be contacted on Freenode IRC. Usually I visit the channels
#javascript, #prolog and #node.js with nick RLa.
