About Justin

Expert nodejs, technical leader, architect, devops. I can assist you with your javascript projects, as a lead, architect, or developer. I have a strong interest in backend development, distributed architectures, and the cloud. I also practice Go.

My experience is very diverse, on websites with (very) high traffic, hidden or not, on full dynamic business applications, on dedicated factories for squads, in an international context...
Which gives me the necessary perspective to help with choices and the implementation of new stacks. I am looking for a positive, dynamic, benevolent context, conducive to individual and collective fulfillment.
