Senior🎓
Top SchoolDale Ragan is a Principal Software Design Engineer with 16+ years building high-availability, cross-platform and embedded systems, currently shaping resilient, immutable infrastructure and tooling at SAP Concur from Redmond. He blends deep systems knowledge—algorithms, language and OS design studied independently—with hands-on execution, having driven a Receipt Service to 99.999% uptime and designed Kubernetes-based immutable deployments across AWS. A pragmatic architect and mentor, he leads end-to-end teams, automates developer environments, and champions DevOps as culture rather than title. Dale is an active open-source contributor to notable .NET projects (GitSharp, ImageResizer, FubuMVC), where he focused on compatibility, licensing features, and code-quality refactors—experience that underpins his emphasis on testability and cross-platform reliability. Early exposure to programming on a Commodore 64 and technical grounding from Army signal-support work give him a practical, systems-first mindset that translates into elegant, efficient code and durable operational practices.
