Profile

“O inverno está chegando”

Black and white side portrait of Jorge Mesquita

I am Jorge Mesquita, a backend developer. I study Analysis and Systems Development at Senac and Software Engineering at UNIFG.

I work with Python, SQL and process automation: scripts and tools that take manual work out of the way, API integration and data handling. I also study Linux, object-oriented programming and good development practices. The discipline comes from before code, from my time at the Brazilian National Police Academy.
