Sebastiaan Janssen

project manager of Umbraco Core at Umbraco

Seb brings the order to the organised chaos. He spends his days wrangling, herding and cracking the whip on our team of devs to make sure we deliver each release on time according to the roadmap. Seb joined HQ after proving himself an Umbraco-Guru at various agencies in the Netherlands.


Stephan Gay

Core architecture and development at Umbraco

As a child Stephan found it more interesting to tear apart video games and understand how they worked, rather than actually play them. After 6 years in IT at HP printers and 5 years as Tech Lead in various press and internet companies he turned back to his childhood curiosity to “do” rather than to “oversee”. When he started using Umbraco for a customer's project in 2008, Stephan naturally looked at what was under the hood. After declaring it "Completely Broken", he started to fix whatever he could fix, one bit at a time. As of 2014 Stephan joined HQ and now works primarily on Core architecture and development with Shannon.
