Hi, I'm Kasra

About Me

Hi my name is Kasra Rahjerdi and I am a programmer. I was born in Ahvaz, Iran, grew up in Seattle, WA, and am a Pisces Cancer Moon Libra Rising.

I live in Los Angeles and mostly hang out with my family, including my three young nephews whom I love dearly.

I work at Abstract Partners where I run a team of very smart developers focusing on ~50/50 ecom and AI projects.

I really, really, really like open source software (I owe my whole career to it!) and helping others learn to program.
