He was technical, and curious, with a dry sense of humor. He liked to think of himself as easy going (as does everyone), though he had to admit that saying this to people he knew usually induced disbelieving laughter. He was indomitably optimistic without being obnoxiously upbeat, and pragmatic without giving up on daydreams. He believed that every dire situation could be improved, and that every dour mood could be lightened. If everything was not going to be fine, he at least knew why, and sought to come up with the best path to making things as fine as possible. Discovering that this pisses some people off had caused him significant and ongoing consternation.
He was a fast but sometimes muddled speaker, and a clearer (if sometimes stodgy) writer; he knew how to use more words than most, though he might not know how to spell all of them at any given time. He had a tendency to concatenate multiword nouns; whether this is was due to high school german class, or just lazy typing, none could say. He was noted both for his knowledge of trivia and his trivial knowledge. He tended to be either quite lazy or intensely active, with less time spent in between than most. He was honest, as he was completely hopeless at the alternative, though he was not entirely guileless. There was a certain charm in his occasional tactlessness, though not everyone saw it as such; he wasn't always a fan of it himself, given the trouble it sometimes caused. On occasion, he could be heard saying romantic things like "you're the kind of girl i will never forget, barring significant head trauma." Don't all message him at once, ladies.
He had a tendency to gravitate to the top of projects that held his attention, and his sometimes obsessive attention to detail stood in remarkable contrast to the disarray left in his wake (and in his basement). He was creative, once he had a framework to create within. He was funny in bursts. His musical tastes were not nearly as eclectic as those of most people, but his playlists generally met with approval from those who heard them. He had been told that he appreciated craftsmanship rather than art, but what this meant was anybody's guess, as far as he could tell.
Ultimately, he was a simple man, with simple needs, simple wants, and maybe even some simple goals. He didn't have much money, but he didn't have any debt, either; he had a roof over his head, plenty of food to eat, and a car with working air conditioning. Life was good, and now all he needed was someone to share it with.
