About Codeminer42

Codeminer42 is a Brazilian software boutique focused on delivering the best value for its customers. We started operating in September 2011, working ever since then with the most professional and competent developers we can find.

Our challenges

We are miners.

Delivering value into any project is an arduous process. As software developers we thrive to deliver not only well written code, but code which provides real value to each client.

It’s not enough to deliver code by itself, but code which solves real world problems and which provides real value. That’s a mission that we, as miners, will continue to dig deep to achieve.
