Experience
FindCars
The project involved creating the infrastructure hosted on Amazon EKS with RDS, using S3 and CloudFront.
My task was to create the infrastructure from scratch with Terraform scripts to make it highly available, scalable, and fault-tolerant. I also designed a CI/CD pipeline using Docker layer caching for faster building and releasing.
