What I'm looking for

I'm looking for remote opportunities to build scalable backend and full-stack systems, automation platforms, real-time applications, financial technology, and AI-driven solutions while growing in DevOps and distributed systems.

I've built production platforms for CPAE and BX Consultoria using NestJS, Next.js, React, PostgreSQL, Docker, and Linux infrastructure. At CPAE, I created a healthcare and educational support platform from scratch, including automated patient triage, backend APIs, authentication, administrative tools, and containerized VPS deployments.

I also build financial and AI-driven products, including automated trading infrastructure, real-time trading terminals, and multi-agent crypto market intelligence workflows. I'm focused on backend architecture, distributed systems, event-driven automation, real-time communication, and scalable cloud-hosted applications.
