Senior🎓
Top SchoolMarcio Barbosa is a senior software engineer and solutions architect with over 30 years in IT and 13 years focused on cloud, DevOps and enterprise architecture. He has led high-stakes projects such as Bradesco’s PIX migration and Brazil’s Auxílio Emergencial, designing scalable OpenShift/Kubernetes platforms and automating infrastructure with Terraform and Ansible. Comfortable across AWS, Azure and GCP, he blends TOGAF/C4-driven architecture, IaC and regulatory security (LGPD/Banco Central) to deliver auditable, production-grade systems. At Red Hat and major banks he built cost-optimized OpenShift clusters and introduced CI/CD and DevOps practices that materially reduced provisioning and delivery times. An active contributor to the Phalcon project, he extended Oracle DB support in a performance-oriented PHP framework—reflecting a pragmatic full-stack perspective that spans low-level database adapters to cloud-native orchestration. Based in Brasília, he pairs deep technical craft with a track record of turning complex, regulated challenges into resilient business-aligned solutions.
