I'm a woman, an artist and an IT developer. Yes, you can be the three together, that's perfectly okay.
I am currently working on the video game The Sundew as pixel art artist, designer and programmer. You can download The Sundew demo from IndieDB, Facebook, or from the game website, and play 20-25 minutes for free (have a look at my games section).
I previously did graphics of the video game Dreadstar: The Quest for Revenge, a retro-style shmup. Read more about it on IndieDB or on the game website (Augmented Irreality | Shoot the core, save the world).
