Gunnar "Nick" Bluth has been feeding his family freelancing with FOSS consulting & services since the late 20th century, as a trainer, systems administrator/engineer/architect, developer and jack-of-all-trades.
In 2013, he switched over to SQL developing (and PostgreSQL advocacy ;-), and in late 2015 became a fulltime PostgreSQL DBA.
He owns and runs a small company (Pro Open GmbH).
Nick still does trainings occasionally, these days on PostgreSQL, of course!
Emba, the dog, sadly passed away in early 2023 :/
