Experience
Adult Dating
A Laravel-based project for a global network of dating sites. I planned, built, and managed the entire project on AWS with scaling in multiple layers. During peak traffic hours, the project handles between 2,300 and 3,900 requests per second.
I built the project with extensive use of AWS, CI/CD pipelines, and Docker. Because of lower performance for RDS, I tuned EC2 instances. The project uses a MySQL InnoDB Cluster with ProxySQL load Balancing.
