J&M Lab is a company that serves as the home base for the projects, companies, and client work of Jeff Mueller and Miriam Mueller.
J&M Lab Consulting was initially a web development company and was in operation from around 2007 through 2020. Jeff created a few apps for the internet, working largely in Ruby. The consulting firm also served quite a few website and app clients over the years. Its owners still occasionally work on and launch projects when ideas strike.
J&M Lab also spun off a totally different company – Miriam’s accounting firm, Happy Bookkeeping, that operated for over a decade.
