About Sergio

I am a Computer Engineer and Multiplatform Developer, with experience in system design, data management, and functional interfaces. But beyond code, I define myself as a critical thinker.

My interest goes far beyond computing: I am passionate about history as a tool for structural analysis, mathematics as the fundamental language of logic, and economics as a field of power and resource distribution.

I explore how these domains intersect and construct the perception of the world, from the individual to the systemic.

I am hardworking, proactive, organized, disciplined, and structured. And my best skill is communicating with clients and developers and mediating their needs.

I have a B1 driver's license and flexible working hours.
