๐Ÿ‘‹ Hi, Iโ€™m Douglas Letz

Senior .NET Engineer | Senior DevOps Engineer | Cloud Infrastructure Architect
โ€œTurning operational chaos into a symphony of automation and efficiency.โ€
๐Ÿ“ Based in Denison, TX, USA
๐ŸŒ LinkedIn โ€ข GitHub


๐Ÿงญ About Me

My toolkit includes .NET, Python, Go, and JavaScript/TypeScript with React, Angular, Vue.js, and Node.js, making me a versatile force across both infrastructure and software development.

Iโ€™m a DevOps maestro with a flair for turning operational chaos into a symphony of automation and efficiency. Whether itโ€™s DevOps, AIOps, CloudOps, DevSecOps, AppOps, ChatOps, MLOps, NoOps, AnalyticsOps, DataOps, GitOps, InfraOps, or even ModelOpsโ€”if it has an โ€˜Opsโ€™ in it, Iโ€™ve probably mastered it.

I build rock-solid CI/CD pipelines, architect scalable cloud solutions in Azure, AWS, and GCP, and orchestrate seamless deployments with Docker and Kubernetes. From APIs to ETL, database optimization to observability, I bring production-grade discipline and speed to every project.
