About the Author

I build with Claude.
I write about everything I learn.

I'm a Principal Solutions Architect at an AWS Premier Partner — with 14+ years designing enterprise cloud infrastructure and 24 cloud certifications across AWS, GCP, VMware, and Nutanix.

I spend my days building real systems: AWS Landing Zones, Claude-powered automation, Bedrock agents, multi-account governance. This blog is where I document the patterns that actually work — the ones I use on production client engagements.

If you're a cloud architect, developer, or technical leader trying to get serious about Claude and AWS, you're in the right place.
