Enhance ThinkPHP UI & Database

My order-brushing platform is already running on ThinkPHP, but parts of it feel clunky and a little slow. I need fresh feature development that enhances what is there rather than replacing it. The immediate focus is two-fold: polishing the user interface and tightening up database operations so large order batches process smoothly.

Here’s what I need done:

• New or redesigned screens built inside the existing ThinkPHP view layer, keeping layouts responsive and the workflow intuitive.
• Refactored model methods, smarter queries, and any new repository classes required to eliminate time-outs during bulk inserts, updates, and reconciliation jobs.
• Code that respects current routing and controller names (other services depend on them) and follows PSR-2 style.
• Clear Git commits and PHPUnit coverage for every change; I’ll review on a staging server before deployment.

If you have previously extended an older ThinkPHP codebase—especially one handling high-volume order data—let me know the highlights and any performance gains you achieved.
