Lady Blessington

Codeminer 42 is a Brazilian software boutique focused in delivering the best value for its customers. We started the operation at September of 2011 and so far we have expanded to 7 different cities in Brazil with the best professionals we can find.

Our speciality is Ruby on Rails web development and it's surrounding ecosystem - that 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, processes automation.

We have worked for small and big companies, we offer an assortment of services that goes from greenfield project development life cycle, legacy projects rescue, 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


We help you organize a team of developers that will work using established Agile best practices towards project management.

Sometimes it's just not possible to have a closed scope to start implementing. Dynamic businesses have changing requirements all the time. The best way to tackle this scenario is to use Agile practices where we start implement what's known to be the most important features first, divide the time in fixed periods - called sprints - and report back at the end of every sprint to have enough feedback to plan for a new sprint. This way you have control over the development velocity, you have what's most important delivered as soon as possible, and have the flexibility to change course to adapt to your business needs.

Ideal for medium to long projects or ongoing operations.

Technical Assessment

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

This is specially useful to understand how your internal software development processes and outcomes are. The idea behind a technical assessment is to give you enough information so you understand it's life cycle, productivity levels, quality levels of the software being produced, and recommendation on how to improve.

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.

Companies that are terminating with another 3rd party and need a reliable partnership.

Who we are

We are miners.

Deliver value in any 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 achieve.
