About Dafydd Rhys-Jones

Infrastructure leader building scalable, reliable platforms in healthcare technology. As Manager of Site Reliability Engineering at DexCare, I lead operations across AWS resources, 40+ environments, and multi-region architectures supporting production healthcare workloads under HIPAA/PHI compliance.I have managed a mixed team of FTEs and contractors, up to 10 people, working with global contractors to ensure successful operation and feature enhancements of our cloud infrastructure in AWS and Azure. I led the design and implementation of our v2 infrastructure platform, replacing a non-scalable, home-grown approach with standardized Infrastructure-as-Code on Terraform — enabling growth from customer onboarding to multi-region deployments without scaling headcount linearly.I drove operational maturity across the engineering organization, establishing processes the company adopts today, including annual reporting for infrastructure project visibility and cost impact. I work with leadership to define team OKRs and KPIs, and co-led initiatives to increase task reporting transparency.In 20••••25, my team managed tickets while delivering $2.25M+ in cost savings through AWS rightsizing, vendor consolidation, and platform migrations including Splunk to Datadog and PagerDuty to Rootly.I partner with executive leadership and cross-functional teams — engineering, product, QA, implementations, and technical operations — to align infrastructure with business direction and serve as a central coordination point for the engineering department, company, and customers.Former Technical Manager In Product Development for a Networking security company, and in Robotics Integration.Created custom framework to translate computer vision to electro-hydraulic response actuation, collect and publish telemetry.Languages & Development: Python, C++, C#, Unity, ROS/ROS2, TensorFlow, Object Detection, Linux/UnixInfrastructure & Cloud: AWS, Azure, EKS, Kubernetes, Terraform, vSphere, CI/CD, Multi-Region Architecture, Platform EngineeringObservability & Tooling: Datadog, Build System Design, Test Automation Infrastructure and ScalabilityNetworking & Security: Enterprise Network Appliances, Virtual & Cloud-Based Environments, HIPAA/PHI ComplianceEngineering & Manufacturing: CAD/CAM, Welding, Plasma Cutting, CNC, CodeSys, Product Development & Lifecycle ManagementBusiness Operations: Vendor & CMO Management, Supply Chain Management, Product Sourcing, Quality Control & Assurance, Sales Pipeline & Inventory Management, Cost Optimization
