My work mostly consist of building and optimizing Ruby applications. I have good knowledge of how Ruby internally work and behave, having working with it from version 1.8 to the new 2.5. I have built most applications using Rails, but I have no problem working on non-Rails applications. I love to create and work on ruby gems. I have contributed to a few, with Hanami is the most well-known.
