The Challenge

Users were churning because the old dashboard took forever to load reports. The codebase was a tangled mess of jQuery and legacy PHP, making new features impossible to add.

Our Solution

We re-architected the frontend using Next.js for static generation of reports and NestJS for efficient API handling. We deployed to Coolify to slash hosting costs.

The Result

User retention improved immediately. The client saved thousands in hosting fees and can now ship new features in days instead of weeks.
