THE PERSON BEHIND THE PROJECTS

It started with
a screwdriver.
It’s still curiosity.

Harvey RayhansonAlso known as Harvey Chowdhury

Media artistGraphic designerAI engineer

Always making.
Always figuring something out.

I’m Harvey, a media artist, graphic designer, and AI engineer who likes understanding how things work, then imagining what else they could do.

I was the kid with a screwdriver in his pocket, taking things apart to see what was inside. That instinct never really left. I still learn by experimenting, breaking things, fixing them, and asking one more question.

Gaming first drew me toward graphic design and a future in the games industry. From there, I found my way into interactive experiences, photography, video editing, and gaming content through RayBits Gaming. As AI opened up new possibilities, I began exploring how it could bring these interests together and help turn ideas into useful tools.

Today, I work across visual design, media, and AI while continuing to build my programming skills and explore cybersecurity. I’m still discovering where these paths meet. Each project gives me a reason to try something unfamiliar and understand it a little better.

I want technology to fit naturally into everyday life: to help us become more capable, use our time well, and make room for the things that matter.

Outside the screen, I sometimes pick up a guitar or write a poem. This portfolio is a growing collection of what I make, what I’m learning, and the things that keep me curious. There’s more than one side to the work, and to the person behind it.
