I stumbled about conference buddy during code.talks 2018 in Hamburg.
Nice idea to have at least one known face around.
I live and work in Hamburg as a Software Test Engineer / Developer since 18 years and go to a conference once a year
As a speaker I prefer smaller audiences, like meetups or usergroups.
I already picked the one to attend for 2019: European Testing Conference in February.
While I survive during the day of a conference, the evening party is usually strange to me, when no coworker is around or somebody else I already know.
Otherwise you see me hiking or bicycling around.
