About
Hi there, I'm a Software developer and have been programming since 2010.
I came in contact with functional programming when I did my master's in computer mathematics. I learned functional programming using Lisp, Prolog and Mathematica. But then I found my perfect language in Elm and never looked back.
At my job, I work with Kotlin and Typescript, which work best by writing a hybrid of FP and OOP.
Ever since I started working, I use field notes to track my thoughts and discoveries. My blog contains the best parts of those notes.
