About

Engineer who owns the path from problem to production.

I am a Full Stack Software Engineer with deep experience shipping production systems for teams in Brazil and the United States. My work sits at the intersection of backend performance, clean architecture and practical AI: APIs, web platforms, automation, and the infrastructure they run on. I also build AI and LLM systems, including model integration, RAG pipelines, multi-agent workflows and full-stack applications.

Today I am a Systems Development Analyst at Absam.io, focused on DevOps, service optimization and AI powered tooling with Python, Go and Rust. Before that, as a Senior Full Stack Developer at PixelClub (New York, remote), I delivered high performance sites and products for national and international clients, with measurable gains in load time and rendering.

Earlier I spent years building healthcare software at Saúde Vianet, and I continue to study data science and machine learning. I am open to international remote roles with product teams that value ownership, solid engineering and clear communication.
