Quinlan Pfiffer

Full Stack Web Developer

I'm a web-focused engineer with ten+ years of experience writing production-quality code for all sorts of applications and places. I'm most at home in a terminal, implementing tests and business logic in a backend environment, though I am more than comfortable building reactive frontends as well.
