About Us

My name is Davi S Evangelista, founder of 5e Contract Programming.

Graduated from the University of Brasilia in Electrical Engineering, I work as a programmer since 2010.

Coding for embedded systems and microcontrollers, I was an engineer in two Brasília (Brazil’s capital) based companies where I’ve worked with several microcontrollers and microprocessors, tailored the kernel 3.2 for a specific hardware, automated work routines, and more.

Now I assist other companies grow helping they focus on their own operations: we take care of their programming needs!
