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

Build, measure, certify

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.

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.

Edge + static frontends

S3 and CloudFront host this site. Knowing cache behaviors, OAC, and DNS quirks is table stakes for Solutions Architects.

Study against real stacks

My SAA nights map to production patterns from Global Ski Atlas and this site — not slide-only learning.

IaC discipline

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

Playground projects

These pages are the AWS lab today — more architecture diagrams and mini-labs will join them.

Platform labs

Same pattern, more stacks

Mapping and cloud playgrounds — each hub explains why I use the platform and links demos as they ship.
