KATT/README.md

Hey there! 👋

I am Alex, a fully-stacked TypeScripter from Sweden & the creator of tRPC.

Been doing html since the late 90s, started a company in 2006 selling Counter-Strike servers & got my first official coding job in 2009. Since then, I have been on 5 continents, lived/worked on 3, and worked for everything from sub 5 people startups to big banks - as a consultant, employee, and founder.

From Sweden, living in Malmö. Speak Swedish, English and rusty (Brazilian) Portuguese + Spanish.

Sponsors ❤️

If you are using my OSS-work for your company or just like what I do - I'd really appreciate if you would consider sponsoring me; there's nothing that gives me more energy than a token of appreciation.
