Software Engineer and Creator

I'm Bill Prin, a software developer and writer living in San Francisco. Previously, I was a software engineer for about 13 years at companies such as Google, Pinterest, and many small startups. My primary career interests are full-stack development, generative AI, teaching, entrepreneurship, and indie app development.
