## About

I work as a software engineer for Tlon, working on their Urbit hosting platform. I have more than 8 years of experience in different environments and companies, ranging from academia to banking and logistics.

I previously worked as a software engineering consultant for Tweag, mainly with Haskell, Nix and functional programming-related tech stacks.I was the project lead for my latest mission, and am an editor for the company technical blog.
