What I'm looking for

I seek senior engineering roles building secure, scalable cloud-native backends and APIs, emphasizing DevSecOps, automation, and measurable cost and risk reductions.

I am a senior software engineer with 19 years of experience designing and building scalable backend systems and APIs in cloud-native environments.

I specialize in Python and Node.js backend development, serverless architectures, RESTful APIs, and data-driven services, and I embed security and quality controls into development workflows.

My work has included cloud migrations, multi-cloud architectures, infrastructure-as-code, and automation using Terraform, Kubernetes, and CI/CD tooling to improve reliability, cost, and compliance.

I have led teams and projects that reduced security risk, cut costs, and improved availability while integrating compliance standards such as HIPAA, PCI-DSS, HITRUST, and NIST into production systems.
