About me


My name is Dionysis Grigoropoulos and I’m in my late twenties. I currently work at Transifex as an SRE. In the past, I worked at Pollfish as a DevOps engineer and before that, I worked as a developer for GRNET’s Synnefo (Synnefo on GitHub) cloud stack platform.

I’m interested in anything related to infosec, from hardware hacks and low level exploitation up to social engineering and web app exploitation. My focus is on automating security workflows.

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 thing. You can find my projects under my GitHub account or my self-hosted stagit instance.

My preferred means of communication is email, so if you want to contact me, drop me an email at dgrig@erethon.com. You can find my public GPG key at the end of this page.

Alternatively, I can be reached via IRC on Freenode under the nick Erethon or by Jabber/XMPP at dgrig@chat.erethon.com.
