You probably can become less introverted with practice if it's something you want, it's hard but not impossible.

How introverted are you ? - web agencies and the like which require client interaction will tend to require more extroverted developers but if you're at a large company working on internal project it tends to be much less of an issue.

If you are introverted there is a good chance you won't want to deal with clients anyway. I know it is the most stressful and draining part of my days. I dread the next work day when I get home.
