Hi, I'm Clint
I build things
for the Internet.
Freelance software developer and architect in Minneapolis. I build web applications that make complex data usable, and I modernize the systems underneath them. Federal health registries, state government websites and businesses. I also write about software, espresso and whatever side project has my attention.
