I’m a certified AWS Solutions Architect Professional and Principal Cloud Architect with 20+ years of experience across cloud architecture, migrations, DevSecOps, and infrastructure automation. Recently, I’ve led GenAI solutioning using AWS Bedrock Knowledge Base and OpenSearch vector indexes, and built event-driven hybrid integrations using services like API Gateway, Lambda, SQS, and SageMaker. I’m passionate about designing secure, scalable platforms, optimizing cloud spend with FinOps, and coaching engineers to succeed.

I’m a Certified AWS Solutions Architect – Professional with 20+ years of experience architecting and delivering secure, scalable AWS solutions across enterprise environments. I build hybrid and event-driven integrations between on-prem systems and AWS using API Gateway, Lambda, SQS, and SageMaker, and I’ve led GenAI/RAG solutioning using AWS Bedrock Knowledge Base + OpenSearch vector indexes, with end-to-end automation via CloudFormation/Terraform. I’m strongly security-focused—defining least-privilege IAM policies, partnering with InfoSec in design reviews, and implementing secure network patterns using VPC architecture and VPC endpoints, along with operational visibility via CloudWatch/CloudTrail.
