Hi! I Just completed the Cloud Resume Challenge, the hard way I would say.

My Project Architecture Diagram

In this post, I share every failed attempt, every 'aha' moment, and the exact solutions that finally worked.

The journey:

Built a multi-account AWS Organization (to familiarize with enterprise-level architecture and cross-account permissions)

Failed with cross-account IAM roles ❌
Failed with S3 bucket policies ❌
Failed with ACLs ❌
Failed with S3 Access Grants ❌
Finally succeeded with S3 Access Points ✅

But wait... Still got Access Denied.

The plot twist? An old ACL setting from attempt #3 was silently overriding everything. One forgotten checkbox. Hours of debugging. Disabled ACLs → instantly worked.

What I built in 2 weeks:

• CloudFront + S3 static site with cross-account architecture
• Serverless API (Lambda + API Gateway + DynamoDB)
• Full Backend Terraform IaC + GitHub Actions CI/CD
• DNSSEC-enabled domain + Playwright testing
• Real-time visitor counter

Biggest lesson: "No error, no gain." Each failure taught me something documentation alone never could.
