03About

A bit about how I work and what I work with.

I'm a Brazilian senior software engineer with around 15 years of experience across modern web platforms and long-running business systems. My recent work is full-stack with React, Next.js, Python, Django, AWS, APIs, databases, and integrations; my earlier background is deep in Delphi ERP, POS, inventory, commercial and Brazilian fiscal workflows.

Business-critical systems

I like practical software: internal tools, dashboards, integrations, ERP extensions, and production workflows that support real operations. I am comfortable owning features end to end, making pragmatic technology choices, maintaining legacy systems, and gradually modernizing the parts that need it.
