Stripe API Fix and Laravel Socket Integration
I am disappointed with this developer's performance. A 15-day project extended to nearly 3 months without completion. They struggled with small fixes, were often unresponsive, and frequently asked irrelevant questions. Despite multiple attempts to guide them, they failed to deliver the expected results and continuously requested payment before any significant progress.
