What I'm looking for

I’m looking for roles where I own end-to-end feature delivery in scalable web products, partner cross-functionally, and integrate cloud infrastructure with strong observability. I want to apply AI capabilities in production-grade systems and work in collaborative, English-first teams.

I’m a Senior Full Stack Software Engineer with 5+ years of experience building scalable web applications and delivering end-to-end features in production. I combine strong frontend and backend execution with cloud infrastructure integration to ship reliable, measurable outcomes.

Over the last few years, I’ve led integrations that directly created business impact—most notably a ticket insurance feature where my full-stack work helped generate over R$300K since launch. I also implemented a PIX payment method end-to-end, covering payment processing, configuration flows, and reporting dashboards.

I’m comfortable working in fast-paced, English-based environments and collaborating with cross-functional teams and external partners, including U.S. clients in fully English-based workflows (C1 proficiency). I also support production with on-call ownership and data extraction via SQL for analysis when decisions depend on real-time signals.

I bring a modern engineering toolkit—React/Next.js, Node.js (NestJS), AWS, Docker, CI/CD, and observability with Grafana and Sentry—and I focus on building systems that are secure, maintainable, and scalable. I’m currently pursuing a postgraduate degree in AI Science to integrate AI capabilities into scalable software solutions, aligning my next projects with where product and technology are heading.
