Our Story
Software culture in the US tends to be competitive even within teams. Many organizations reward heroics and many developers gaurd their own work jealously from their teammates. This is not the way.
In Argentina, for broad cultural reasons, people tend to like to work together and support each other. Kelsus has noticed this and amplified it. We hire for teamwork, follow-through, dedication to craft, great communication, and flexible mindset.
This recipe attracts the best of the best to our team.
