About Me

About Mebehind the projects

Marcus Paixão

I'm a Full Stack developer, and I like to follow the work from end to end, as in the projects you've just seen. I hold a degree in Systems Analysis and Development from UNIP and a technical certificate in Systems Development from ETEC Basilides de Godoy (2023).

Today I'm part of the Innovation and AI Squad at ALFA ERP. I develop SAP Business One integrations, automations, customer portals and implementation tools, using Node.js, React, TypeScript and PostgreSQL with the Service Layer.

Previously, I worked as a Full Stack developer at Cresci e Perdi, building complete web applications and managing Linux servers. My foundation came from support, ERP systems and SQL Server, with experience at JBS and KingHost.

This path gave me an end-to-end view: understanding the problem, developing the solution and following how it works. I believe technology needs to have a real impact on people's lives and on companies' daily work.
