@KrzysiekDróżdż I've looked at a few profiles but do not see a "contact me" or "open for work" indicator / button. That would be a great feature for user profiles.

if someone was open for work, and it showed a button i could click and send them a message

there's a careers site for that

but I wouldn't expect the pool to be large

local WordCamps and meetups are a much better way
