About
Who's on the other side.
I'm Jean, 21 years old, studying Systems Analysis and Development at UNOESTE. I work from front end to back end and take care of the infrastructure: websites, systems, APIs, deployment and automation.
For 3 years I've been serving and selling to customers at a store counter. I know how to listen, find the real problem and explain the solution without jargon.
In code, I think in well-separated layers, performance from day one and interfaces that make people feel capable.
