About Me

Faisal Hakimi - Profile Picture

I'm a passionate full stack engineer with over 7 years of coding experience and a B.S. in Computer Science from San Francisco State University, which I earned in 2022. I've worked at early-stage startups where I wore many hats, collaborated closely with founders and designers, and built products from the ground up. I thrive in fast-paced environments where building and shipping quickly drives real impact. From responsive UIs to scalable backend systems, I love turning complex problems into elegant solutions.

When I'm not coding, you'll find me experimenting with new technologies, exploring nature, capturing moments through photography, trying new foods, lifting weights, watching sports, working on cars, and gaming (Call of Duty is my go-to). I'm also a huge animal lover—especially cats.
