My character concept:

"Cartographer", a narcissistic (so it's like talking to a TV, while he is talking to an audience) adventuring pretty boy who enjoys relaying all information. Succinct in report writing and relaying information, proficient in coding (to include updating the map which he's forever tweaking to make better and clearer visuals with the tools he has). A bit of a MacGyver and certainly the shipboard blogger. He lives for the number of hits or views their ship's "adventures" get and enjoys hyperbolizing virtually everything. He's a bit of a self-made man and somewhat of a troublemaker, thought to have gotten into the project as the result of "luck" (in this case, being one of the Earth board of trustee's enthusiastic nephew). Though he comes across as rather dim-witted because he's an "ooh shiny" complex, he's well-versed in the finer points of code and is a capable firefighter (for all of those space board emergencies). He's testy with some of the members because he's forever feeling like he has to prove himself and his worth. Which is says the proof is in the pudding. No literally, he's the best ship's cook and is able to make a feast out of the dehydrated eggs. He just asks that nobody asks him how he does it. He tosses in his vote (if there's ever such a thing, which he's convinced himself there is despite the presence of a singular "captain") with whichever option sounds like it'd be more foolhardy AKA "fun." More complexity to come, but I'd say that his role could fit the "face" of the ship and he'd be a quick learner for any language, not solely code. So translations would be reasonable if you can get him to do them. He'd be your comms guy and he knows enough about electronics to be able to make repairs (especially if he's under pressure, stressed, and has few resources) otherwise he can be a bit lazy about "getting around to it."
