reversed → "disbtom" ? That doesn’t look quite right — let's try again.
But the clearest guess: reversed letter-by-letter → "disbotm" → anagram for "bottom dis" or "bottom ids" ? Not likely.
Given common IT terms, "otb driver" is plausible (OTB = Off-The-Book / Off-The-Board / Over-The-Board? Or in racing: OTB = Off-Track Betting).
