How about a God/ess of sandblasting?
I suspect that Brigid already has that covered, since she's the Goddess of Smithcraft; back in pre-Christian times when the Pagan gods and goddesses were first being recognised, or discovered, or invented or whatever, smithcraft was perhaps the highest level of technology available to the humans of that era. Nowadays of course, Brigid's responsibilities cover all aspects of metalworking and indeed perhaps technology generally.
But perhaps she delegates responsibility for other specialties within technology to lesser deities? Perhaps there's a God of sandblasting, a Goddess of non-destructive testing, a God of open-hearth steelmaking, a Goddess of solid-state electronics?
Then there's Eris, the Goddess of chaos, confusion and bureaucracy, with perhaps a sub-specialty of computer programming. Certainly some of the fundamental principles of computer sciences seem to partake strongly of chaos and confusion ..... think of "There is always one more bug," and "The most destructive bug is the one you don't find until the software is installed on all your computers - and then the only way to debug it is by ripping apart the whole system....."
Eris is closely related to Murphy, the God of Whatever Can Go Wrong, Will; and the shadowy, nameless Goddess of Even Things That Can't Possibly Go Wrong, Will Still Go Wrong - And in the Most Destructive (And Expensive) Way Possible.
Blessed Be, and may the Gods and Goddesses not give you too much grief.
