I build backend platforms, APIs, and automation for software delivery.
BrazilWhat I'm looking for
At Red Hat, I build backend services, developer tooling, and deployment workflows for Red Hat Learning Subscription. I developed a production Django integration for an AI assistant and a content-ingestion pipeline using embeddings, PostgreSQL, pgvector, and OpenShift.
I connect application development with the infrastructure that supports it, using Python, Django, PostgreSQL, Kubernetes, OpenShift, Ansible, Tekton, and Docker. My work includes internal APIs, highly available web architectures, developer environments, automated validation, and GitHub-to-Elasticsearch content synchronization.
Earlier, I delivered infrastructure consulting and more than 100 Red Hat-certified courses across Linux, OpenShift, Ansible, JBoss EAP, OpenStack, and related platforms. I bring systems administration, technical consulting, and teaching experience to helping teams build, deploy, and operate software.
