AWS architect needed to build architecture solutions for the applicaiton

I am looking for an experienced AWS architect to help me build architecture solutions for my application. The architecture needs to utilize the best practices of AWS and introduce innovative ideas. I am anticipating implementing either a serverless solution, data lake solution, or a microservices-based solution. Additionally, I require support integrating with a third-party tool. This project requires the use of AWS services such as DynamoDB, EC2, and RDS. If you have any relevant experience and an understanding of how to create a secure and effective AWS architecture, then I would love to hear from you.
