..and if you don’t have this you will have the opportunity to develop in this direction ;)

  • We practice Code Review, Continuous Integration, Scrum/Kanban, Domain Driven Design, Test Driven Development, Pair Programming, depending on the team
  • Our internal ecosystem is based on self-service and widely used tools, such as Kubernetes, Docker, Consul, GitHub or GitHub Actions. This will allow you, from day one, to develop software using any language, architecture and scale, restricted only by your creativity and imagination. 
  • To match the scale, we also focus on building entire Platforms of tools and technologies that accelerate and facilitate day-to-day development, and we ensure the best Developer Experience to our teams
