01 / About
Hands-on technical leadership
I have spent 12+ years building large-scale, cloud-native enterprise applications on C# / .NET. Today I lead three engineering teams at Optum, delivering event-driven microservices with .NET 10, Angular micro-frontends, Kafka, Docker, Kubernetes, and Argo CD GitOps.
I work deep in Domain-Driven Design, CQRS, and clean architecture, and I care a great deal about developer productivity, mentoring, and integrating GitHub Copilot and generative AI into how teams ship.
I also run Zachary Lockhart Consulting, delivering full-stack solutions with Angular, React, C#/.NET, AWS, GCP, and Firebase.
