Alvin Okoro
Senior Software Engineer
About
I build AI products, developer tools, and the systems underneath them.
Senior Software Engineer at Velio. I run Nullish Studio. I ship things engineers and startups actually use.
Work
At Velio, I build software that has to hold up at scale. At Nullish Studio, I work with agencies and startups to ship web and AI platforms.
Faisca is the one I'm building for myself: a canvas for collecting references and shaping creative direction. Bootstrapped, in beta, open now.
The full history is in my resume.
