About me / Work with me


My name is Dionysis Grigoropoulos, but online I go by either dgrig or Erethon.

My tech interests lie in security, infrastructure, radio communications, mesh networks and embedded systems. I like to automate as many things as I can, as well as have everything defined as code and make things reproducible and documented.

I believe in decentralization and the open web. I self-host a number of services for myself, friends and family and wish to help more people do the same. You can find projects I contribute to under my GitHub and SourceHut accounts.

I've worked at Element on the Matrix ecosystem as a Senior SRE. Prior to that, I worked at Transifex as an SRE, Pollfish as a DevOps engineer and further in the past as a developer for GRNET’s Synnefo (Synnefo on GitHub) cloud stack platform.

I'm available for contract work in the following areas:

I'm available at dgrig@erethon.com. For secure communications, you can find my PGP key at the bottom of this page. Alternatively, I can be reached via Matrix on @dgrig:erethon.com.
