Dana Payment is a high-traffic payment platform modernized to handle up to 10 million requests per day. The project focused on optimizing a legacy CodeIgniter 3 (CI3) system to improve performance, stability, and scalability without disrupting existing business operations.

The modernization included backend optimization, database performance tuning, API restructuring, and infrastructure readiness to support heavy transaction loads. The result is a faster, more resilient system capable of maintaining reliability under peak traffic while remaining compatible with the existing CI3 codebase.
