To have just
The structure used to say you have just done something works in a similar way to the one used with "depuis". Use the
present tense of the verb "venir" (see irregular verb list), followed by "de", followed by the infinitive of whatever verb you
wish to use.
e.g. Je viens de finir mes devoirs I’ve just finished my homework
Il vient d’arriver He has just arrived
Elles viennent de partir They have just left
