São Paulo, Brazil
I have 20 years of experience in technology, including 16 years in infrastructure and platforms. I connect engineering leadership, cloud architecture and operations to improve reliability, cost efficiency and developer experience.
At Descarbonize, I manage infrastructure for Aldo Solar and SolAgora, combining leadership and architecture across AWS, Amazon EKS, observability and C#/.NET application environments. Previously, at Raízen Financial Services, I led an eight-person SRE, DevOps and DBRE team and later coordinated 35 people across software engineering, data and infrastructure supporting Shell Box.
- Engineering leadership: developing multidisciplinary teams across Software Engineering, Platform Engineering, SRE, DevSecOps and Data Engineering; aligning technical priorities with business goals.
- Platforms and cloud architecture: building cloud-native foundations, automating infrastructure and improving the experience of teams delivering software.
- Reliability and security: strengthening observability, incident management and security practices throughout the software delivery lifecycle.
Results delivered together with the engineering teams:
- Reliability: improved overall availability across 120 microservices from approximately 97% to 99.9%.
- FinOps: achieved approximately US$10,000 in monthly savings across cloud and databases, with cost reductions of approximately 30% and 40%, respectively.
- Delivery and quality: achieved delivery rates above 80% per sprint and 90% per Program Increment, with production bugs below 5% of the total number of stories; built Jira indicators reported directly to senior leadership.
- Platform modernization: migrated Rancher RKE to Amazon EKS, introduced OpenTofu infrastructure pipelines and Argo CD GitOps, and led cluster upgrades without downtime.
- Developer experience and security: introduced Backstage, automated repository creation, standardized GitLab CI/CD templates and integrated Veracode SAST/SCA pipeline gates.
- Payments: coordinated Shell Box digital wallet DDA capabilities, Celcoin and Yuno integrations, and the migration of payments from Mercado Pago to Cielo.
- AI in engineering: introduced Cursor and Kiro, automated code review with agents and encouraged AI adoption across development teams.
My public repositories are a place to explore my code, technical interests and experiments.
- Cloud and platforms: AWS, Amazon EKS / Kubernetes, Karpenter, KEDA, Backstage, Cloudflare.
- Infrastructure and delivery: OpenTofu, Terraform, Argo CD, Argo Rollouts, GitLab CI/CD, Jenkins, Ansible, Docker.
- Observability and SRE: Datadog, Grafana, Kiali, SLOs/SLAs, incident management, high availability and recovery processes.
- Security and FinOps: Veracode SAST/SCA, SonarQube, MFA, cloud and database cost optimization, Kubecost.
- Software and automation: Python, TypeScript / Node.js, React, Go (Gin), Cypress; architecture and leadership in C#/.NET environments.
- Leadership: people development, PI Planning, Scrum, delivery metrics, architecture governance and coordination with product owners.
