Gabriel Velo is a pragmatic generalist programmer from Argentina with roughly two decades of hands-on experience building systems in C/C++, Java, Scala, JavaScript, Python, Go and Rust. He specializes in cloud-native infrastructure and orchestration (Kubernetes, Docker, Istio, Envoy, Nginx) and infrastructure-as-code (CloudFormation, Terraform, EKS/ECS), pairing low-level systems expertise with production-ready deployment practices. Notable open-source contributions include backend work on the high-profile Qdrant vector database, where he implemented payload management features and on-disk persistence for geo and B-tree numeric indexes—evidence of deep understanding of database internals and data durability. Comfortable across the stack, he favors pragmatic, auditable solutions that translate complex requirements into reliable, deployable software.
