I need a developer who can add a secure money-out feature to my existing mobile app so users can withdraw their balance directly to their ESEWA wallet. The core flow is straightforward: a user enters the amount, confirms with a PIN or biometric prompt, the app calls ESEWA’s withdrawal API, and we show real-time status updates until the transfer is complete. You should already be familiar with ESEWA’s API endpoints, auth tokens, callback handling, and the standard security practices for e-wallet transactions on Android or iOS. The current codebase is built in Flutter, so I’d prefer to keep the integration in Dart, but I’m open to a native plug-in if a specific SDK requires it. Acceptance criteria • Clean, well-commented code that plugs into my existing balance screen • Successful test withdrawals on ESEWA’s sandbox and production environments • Proper error and timeout handling with user-friendly messages • A short hand-over note explaining any configuration keys and how to re-deploy the build If you’ve implemented ESEWA (or a similar e-wallet) before, please mention it along with links or screenshots of your past work so I can move quickly.

I will deliver clean, well-commented Dart code that plugs smoothly into your current balance screen, complete with PIN/biometric confirmation, proper error handling, timeout messages, and successful withdrawals tested on both ESEWA sandbox and production. I will also share a short hand-over note covering configuration keys and build steps so you can manage deployments easily. I need your current Flutter codebase, ESEWA merchant credentials, and any existing flow logic for balance calculations so I can begin the integration immediately. Thanks, Rahul A.

Hello, I can help you integrate a secure, reliable “money-out” feature into your Flutter app using the official eSewa withdrawal APIs. I’ve worked with wallet platforms that follow similar flows—token-based authentication, callback verification, and strict timeout/error handling—so I’m very comfortable delivering the exact interaction you’re aiming for: enter amount → secure confirmation (PIN/biometric) → API call → real-time status updates until completed. My approach is to build a clean, modular Dart service that plugs directly into your existing balance screen without disrupting current logic. I will implement robust validation, withdrawal status polling, and graceful handling of failures, timeouts, and invalid responses, with clear messages tailored for the user. Both sandbox and production endpoints will be fully tested, including token refresh logic and callback events. If any part of the eSewa workflow requires native handling, I can also bridge it through a lightweight Flutter plug-in. Upon delivery, you’ll receive well-commented code, configuration notes for keys and environment variables, and a short deployment guide so you can adjust credentials or rebuild confidently. If needed, I can also assist with refining the UX around the confirmation and transaction-tracking screens. Best,

Hi, how are you doing? I’m ready to add a secure ESEWA money-out feature to your Flutter app! I understand the flow: users enter the amount, confirm via PIN or biometric, the app calls ESEWA’s API, and shows real-time transfer status. I’ll integrate ESEWA using Dart, handling authentication, callbacks, and errors with clean, well-commented code. The feature will work in sandbox and production environments, include user-friendly messages, and come with a short hand-over note explaining configuration and deployment.

Hi Aayan, I’ve reviewed your ESEWA withdrawal feature and I’m confident I can deliver a secure, reliable Dart/Flutter integration that plugs cleanly into your balance screen and provides real-time status updates until the transfer completes. With hands-on experience building Flutter apps that talk to e-wallet APIs, handle auth tokens, callbacks, and secure flows, I’ll implement a lean module in Dart (with an optional native plug-in if required) that: - lets users enter the amount, confirm via PIN or biometrics, and triggers the ESEWA withdrawal API; - tracks progress via status polling or callbacks and shows friendly, real-time UI updates; - enforces robust error handling, timeouts, and retry logic; - ships clean, well-commented code that can be dropped into your existing balance screen, with a concise hand-over note for config keys and deployment steps. Deliverables include sandbox and production test withdrawals, clear error messages, and a short hand-over doc. I’ll provide a minimal test harness to validate the flow on both environments. I’m ready to start and can align with a 14-day timeline, including a quick kickoff and weekly updates. To tailor the integration, do you have any specific security requirements for ESEWA API authentication (e.g., token rotation, HMAC, webhook verification) that I should enforce, and are there preferred test accounts or environments I should use first?
