Principal Cloud Architect · AWS Solutioning & Engineering · Distributed Systems

I am a hands-on cloud architect and principal engineer with 25+ years building enterprise systems across healthcare, finance, logistics, retail, and aerospace. I turn ambiguous platform goals into engineered systems with clear boundaries, measurable behavior, and production-shaped operations.

My work spans secure multi-account AWS foundations, serverless platforms, GenAI/RAG workloads, data pipelines, identity boundaries, observability, and Infrastructure as Code. I bring deep experience with AWS Organizations, Control Tower, IAM, security guardrails, Lambda, Step Functions, OpenSearch, Bedrock, EKS, Terraform, and CloudFormation.

I bridge solution strategy and engineering execution, building working reference architectures that demonstrate how platforms should behave under real production constraints.
