The hiring process, explained

we use


All of our work is on GitHub. Everything goes through pull requests and code reviews with your future team members.

GitHub Actions

We use GitHub Actions to automate our CI/CD pipeline, ensuring that our code gets from development to production with minimal fuss.

New Relic

New Relic is our go-to solution for monitoring the performance of our apps so we can make sure there are no bottlenecks that stop everything from running smoothly.


On some projects we add Docker to our toolkit to bundle up our apps and dependencies, making deployment a breeze.


Our go to cloud-computing platform which we use for hosting our apps, working with databases, storing files and other features.


Sidekiq is our behind-the-scenes hero, handling all those background tasks and making sure our apps stay lightning-fast.


The standard is our preferred solution for server-client data exchange. We’ve built multiple gems that simplify data extraction, serialization, etc.


We rely on bugsnag for capturing errors on our applications. When a problem occurs in our code, Bugsnag automatically creates an event and notifies the whole development team.


A Ruby static code analyzer and formatter, created by the community to make clean code, by following the best practices used by Ruby developers.


Tests are an important part of our projects, and we use the RSpec testing framework for Ruby and as well for Rails. It is the most frequently used testing library for Ruby in production applications.


Our in-house developed Rails gem for automatically generating API documentation from Rspec tests.


We’ve built an application that observes the health of every active project and notifies us about new CVEs. We frequently update our dependencies and like to keep our apps and infrastructure up-to-date.


Most of our projects are managed using Productive, in-house software which substitutes Jira, Asana, Trello and other issue tracking products.


​Whether remote or in the office, Slack enables us to exchange information, discuss code, make decisions quickly and stay on top of things.


Through the years we’ve built a vast repository of knowledge related to ruby, rails and backend in general. It also serves as our guide and shows how we make our applications.
