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.
