Serverless GIS backends
Lambda + API Gateway + DynamoDB is still the fastest path from a map idea to a durable API — the Cloud Resume Challenge pattern scaled up.
Cloud architecture with a GIS engineer's bias toward working systems.
S3, CloudFront, Lambda, API Gateway, DynamoDB, and the rest of the Well-Architected toolbox — practiced on this site and Global Ski Atlas.

Why AWS
AWS is where I learned cloud by shipping: this resume site, visitor counters, and ski-atlas pipelines. The SAA study plan turns that production muscle into exam-ready architecture judgment.
Lambda + API Gateway + DynamoDB is still the fastest path from a map idea to a durable API — the Cloud Resume Challenge pattern scaled up.
S3 and CloudFront host this site. Knowing cache behaviors, OAC, and DNS quirks is table stakes for Solutions Architects.
My SAA nights map to production patterns from Global Ski Atlas and this site — not slide-only learning.
SAM templates and CI/CD for the visitor counter taught me to treat infrastructure like code — and to separate frontend from backend deploys.
Built on AWS
These pages are the AWS lab today — more architecture diagrams and mini-labs will join them.
