I'm not sure if this is supposed to be Dolt or DoIt, but using a swear word for a name (even a relatively mild one) is pretty distracting, IMHO.
DoIt isn't really a swear word. It's a euphemism for coitus. It's also a very common phrase in general so it really isn't strongly associated with "doing it" to cause any issues with English speakers. Aka it's fine as a project name. See Nike's "Just do it." advertisement campaign, they would have never gone with the phrase if it had strong negative connotations.
