Krister Viirsaar

I've been building businesses and software since 2014, now with AI. I lead data teams, build products, and teach developers and vibe coders. This is the background behind the services I offer on the home page.

  • Viru Keskus — I lead the data warehouse and BI platform team.
  • Freelance AI and automation work for SMEs — direct, with no agency markup.
  • Training vibe coders who want a developer's perspective.
  • Teaching programming at TechnoTLN (formerly Polütehnikum).
  • Tinkr.techlearn to program by building projects.
  • Kirbs.eesell your kids' clothes effortlessly.
  • Liid.eean AI-powered lead generator for the Baltics and Nordics.
