What I'm looking for

I'm looking for remote international contractor or B2B roles where I can stay hands-on while leading technical delivery, architecture, code quality, and production readiness.

At Gemina, I built a cybersecurity monitoring application from the ground up, selecting its Node.js and React stack and defining the initial architecture.

I stay hands-on across backend and frontend delivery while owning technical decisions, code review, testing expectations, and architecture evolution. I also mentor developers on validation and release discipline during deadline-heavy work.

Previously, I developed EV charging dashboards and platform services at S44 Energy, including PostgreSQL structures, APIs, Docker, AWS, GraphQL, and GitHub Actions delivery. I've also built sales portals, React Native applications, and backend services for remote teams in the United States and Canada.

My experience spans C#/.NET, TypeScript/Node.js, React, cloud platforms, mobile development, Unity, Unreal Engine, and interactive systems. I work remotely from Brazil and am available for international contractor or B2B roles.
