I build secure, scalable C#/.NET APIs and distributed services for mission-critical workflows.

At Lockheed Martin, I lead delivery of distributed C#/.NET and ASP.NET Core backend capabilities for mission-critical defense workflows, turning ambiguous requirements into API contracts, data models, and phased releases. I build secure, high-performance services and traceable data pipelines that support reliable integrations, auditability, and compliance reviews.

Across ProActive Technologies, ECS, Electronic Arts, and independent client work, I've delivered full-stack applications, cloud-hosted simulation systems, data integrations, telemetry tools, and high-volume event processing. I own work from architecture through CI/CD, testing, observability, troubleshooting, and post-release support using Azure, AWS, Angular, React, SQL Server, and modern .NET.
