Summary
👤
Senior🎓
Top SchoolJoshua Castillo is a DevOps Developer and Platform Architect with over a decade of hands-on IT experience, currently focused on cloud-native pipelines and Kubernetes-driven platforms for the Fieldglass application. He has led large-scale automation efforts—authoring an immutable SQL rollout for 450+ databases, designing a Java-based Kubernetes Operator to manage 900+ tenant configurations, and cutting DBA requirements and manual interventions by large margins. Comfortable across Azure, AWS, and on-prem environments, Joshua blends infrastructure-as-code, CI/CD, and service-mesh patterns (Istio, Helm, Argo) to turn legacy systems into repeatable, multi-tenant cloud services. His background in military and enterprise environments sharpened operational rigor: he’s delivered measurable cost and time savings (including an 80% reduction in off-site calls and major man-hour reductions). A clear communicator and team-driven leader, he pairs platform-level architects’ vision with hands-on scripting and automation (PowerShell, Fabric8, Quarkus) to keep delivery predictable and auditable.
