Recommendation

What others say

Simon Høiberg

Developer, Founder & Tech Influencer

I've had the pleasure of working with Johann on Direflow, an Open-Source Web Component framework.

Johann is a highly skilled JavaScript and Node.js developer with an in-depth understanding of the TypeScript typing system. He has an outstanding eye for details, is not afraid to raise questions or concerns, and is generally curious and enthusiastic about his work.

Especially in a distributed collaborative constellation, as we have had at Direflow, I've been impressed with Johann's ability to handle PRs, code reviews, and at times hectic release cycles.

I can only recommend hiring Johann!
