    Bio

    Hi there!

    My name is Boro Sitnikovski. I have a Master’s degree in Informatics and work professionally as a Software Engineer.

    I work at Automattic. I contribute to a lot of open-source projects. That is because I am a strong believer in open source. I am happy to do this, knowing that the code I write runs on millions of machines and has a positive impact. I also learn a lot on the way to doing this.

    – Introducing Software Verification with Dafny Language
    – Introduction to Dependent Types with Idris
    – Introducing Blockchain with Lisp
    – The Mirrors In Us
