I work at a medium sized web agency (~60 employees) as a developer and consider myself introverted. For the first year I worked in a client facing role, which exhausted me - long hours, a lot of social interaction. It wore me down almost to the point of burnout. I then made a lateral move to a non client facing team which greatly improved my quality of life here. So there may be hope for you at a larger company that has non client facing roles - but you may need to work yourself up the ladder to get into them.

You can't change your underlying personality, but you can work on being more social. It's definitely not easy (at least not for me) - when in social situations during the workday, my internal monologue is usually saying "I'd rather be coding." It takes time and practice, but it's achievable. I've been working at being more social and have seen some success.
