What I'm looking for

I’m looking to lead architecture and technical governance for scalable, event-driven platforms on AWS—especially in regulated fintech or public-sector contexts—where I can blend hands-on development, observability, and cost-effective DevOps to ship reliably.

I’m a software architect with 9 years of experience in software architecture, technical leadership, and cloud infrastructure. I’ve worked in regulated environments—Brazilian Federal Police and fintech under Central Bank regulation—contributing to Pix and Open Banking projects, and I build scalable platforms from inception to high-volume production.

I combine deep hands-on development (Node.js, Java, PHP, React, Angular) with consolidated practice in architectural decisions, standards definition, and technical governance. I focus on microservices, event-driven architecture, and strong engineering fundamentals, from API design to async messaging and observability.

In my current role as Senior Software Engineer at Raio Benefícios, I work on the platform team for a high-scale benefits card solution. I build and maintain critical services for transaction processing, distributed ledger, and real-time reconciliation, while contributing to event-driven architecture, platform scalability, and observability in a high-availability context.

Previously, as Technical Leader and Solutions Architect at Ignis Tecnologia, I led the technology area and served as architect and tech lead of the Wishme platform. I designed the platform architecture from inception, scaled it to hundreds of thousands of users, built AWS infrastructure with IaC in Terraform and CI/CD pipelines, and led cost optimization initiatives—while mentoring teams and coordinating multiple regulated client projects.
