São Paulo, Brazil · Open to relocation to the United States
Lead Software Engineer with over 20 years owning the full software development lifecycle, now focused on AI/GenAI, data engineering and automation. I take autonomous AI agents and RAG systems from proof of concept to production, migrate monoliths to microservices on Kubernetes, and standardize CI/CD, Infrastructure as Code and observability across AWS, GCP and Azure.
- Clean architecture, reliable data pipelines and secure cloud-native platforms.
- Engineering leadership: mentoring, code review, career plans, DORA and SPACE metrics.
- Security by Design and DevSecOps, including PCI-DSS and LGPD/GDPR contexts.
Most of my work was delivered inside company organizations and private repositories. I document the engineering behind it in the open: Engineering Case Studies — context, architecture, trade-offs and measured outcomes.
