1.) St. Joseph the Worker.
2.) The patron saint of whatever it is you hope to do, or do, for a living. In my case, I would ask the intercession of good old St. Isidore of Seville, patron of computers and databses, along with St. Gabriel (networks) and St. Clare (telecommunications).
Do a google search on “patron saint” and your field of endeavor to find out who is your patron.
