I’m ready to add Bangladeshi mobile payments to my app and need a straightforward integration of both bKash and Nagad. The core scope is intentionally lean so we can stay focused and deliver quickly: • Payment processing – let users pay through either wallet and return a clear success / failure response. • Transaction history – pull and display recent transactions so customers can confirm their payments. You can wire this up in the language or framework you’re most comfortable with; a clean RESTful approach is fine. I’ll supply API keys and a staging server. Your deliverable is: 1. Well-commented source code for both gateways. 2. A brief setup guide so I can drop it into production. 3. Post-deployment check to confirm live payments run smoothly. If you’ve handled bKash or Nagad before, even better—mention it so we can move fast.
