AWS Certified Cloud Practitioner | Cloud Infrastructure & Automation
Summary
AWS Certified Cloud Practitioner currently preparing for the Solutions Architect Associate certification. Background in BIM engineering with strong experience in structured technical workflows, multidisciplinary coordination, and process automation. Built multiple production-ready AWS platforms: a serverless resume platform (API Gateway, Lambda, DynamoDB), a container deployment platform (ECS Fargate, ECR, ALB), and a cross-platform Android/Windows app backed by Cognito, S3, Lambda, EventBridge and SNS — all infrastructure managed with Terraform and deployed via GitHub Actions CI/CD.

Cloud Projects
-
AWS SAA-C03 Practice App
Built and published a cross-platform Android/Windows quiz app to help engineers study for the AWS Solutions Architect Associate exam. Backend uses Cognito (Google OAuth, PKCE), S3 for per-user score sync and question reporting, Lambda + EventBridge for digest email notifications via SNS. Infrastructure managed with Terraform, CI/CD via GitHub Actions. 1,000 scenario-based exam questions across all SAA-C03 domains. -
Mini Cloud Deployment Platform
Built a reusable container deployment platform on AWS using Terraform, Docker, GitHub Actions, Amazon ECR, Amazon ECS Fargate, Application Load Balancer, and CloudWatch Logs. Implemented remote Terraform state with S3, least-privilege CI/CD IAM, and ECR lifecycle cleanup for cost-aware rebuild and destroy workflows. -
Cloud Resume Challenge (AWS)
Built a production-ready resume platform on AWS using S3, CloudFront, Route 53, API Gateway, Lambda, and DynamoDB. Infrastructure is defined with Terraform and deployed via GitHub Actions CI/CD using OIDC and least-privilege IAM roles.
