Hello Dear, With more than 18 years in IT among which 7 in AWS, I am the Certified Solution Architect you are looking for. I shall study your requirements, design, and architect a technical solution that will use the corresponding services in AWS and finally will implement it. The implementation can ultimately be done in Terraform or CloudFormation, therefore you will have your infrastructure defined as a service and you can replay it anytime you desire. Of course, the solution I will design for you will adhere to the AWS Well-Architected Framework: that is it will be cost-effective, excel in operations, reliable, performant, and secure. I will conclude the project by delivering a Technical Architecture Document for your references. Lastly, I would like to let you know I possess extensive experience building Web App type of solutions (EC2, RDS, Cloudfront, ALB, Route53...) as well as Modern Web Apps(API Gateway, Cognitio, Fargate & DynamoDB).
