About

"Genius is the gold in the mine; talent is the miner who works and brings it out."
Lady Blessington

Codeminer42 is a Brazilian software boutique focused on delivering the best value for its customers. We started operating in September 2011 and so far we have expanded to 12 different cities in Brazil with the best professionals and developers we can find.

Our specialty is Ruby on Rails web development and its surrounding ecosystem, which includes cutting edge new technologies. We are very experienced in delivering all kinds of tech products, such as e-commerce, e-learning, social networks, content management systems and process automation.

We have worked for small and big companies, offering an assortment of services that range from greenfield project development life cycle to legacy project rescues, nearshore outsourcing, and so on.

If you want to have not only a great web application in production but also improve your software development processes and quality assurance, we can help.

What we do

Outsourcing

You will have a predictable cost and an expected delivery date and we will manage the implementation using agile best practices. The scope is variable and we frequently reassess what's to be built, so you have the software you really need at the end.

Ideal for companies that don’t have an internal development team.

Team Augmentation

We identify the best team to help you achieve your goals.

You might already have an internal core team that needs to tackle more than they can implement until certain deadlines. The best thing to do in this case is to divide and conquer. Leave the core team doing the core software and bring in some help from us on new features, extensions and maintenance, in order to meet the required deadlines. We will work within your agile processes, together with your team.

Ideal for companies with an established internal team.

Technical Assessment

You have a big operation and want to make sure you're using the best practices.

This is especially useful to understand how your internal software development processes and outcomes work. The idea behind a technical assessment is giving you enough information so you understand your life cycle, productivity levels and quality levels of the software being produced. With this, you will also get advice on how to improve.

Ideal for companies that maintain their own software.

Project Rescue

You want to bring health back to your product.

You already have source code implemented either already in production or not, but you're insecure if it's done in a safe, quality, and/or scalable way and you need to make sure you can keep adding new features and growing your userbase without unfortunate surprises. We can fix your project and bring it back to life.

Ideal for companies that are terminating with another 3rd party and need a reliable partnership.

Who we are

We are miners.

Delivering value in every project is a very hard process. As software developers we strive to deliver not only well written code, but code that delivers real value to each client.

It's not good enough to just be concerned with code for code's sake, but to deliver code that solves real problems and delivers real value. And this is the mission that we, as miners, will keep digging deeper to accomplish.
