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.

⭐⭐⭐⭐⭐ Valuable Client, CnELIndia and I, Raman Ladhani, can implement your ESEWA money-out feature end-to-end within your existing Flutter codebase. We’ve delivered secure wallet, banking, and payout flows for multiple clients, including integrations using token-based auth, encrypted PIN/biometric verification, and real-time callback handling. Our approach: • Review your current balance module and map the withdrawal UI/UX. • Integrate ESEWA withdrawal API in Dart, or create a small native plug-in only if required by the SDK. • Implement secure PIN/biometric confirmation, token refresh, error/timeout handling, and transaction-status polling. • Run full tests on ESEWA sandbox, finalize production keys, and harden the flow with logging and retry logic. • Deliver clean, documented code plus a concise hand-over note covering keys, environment setup, and build steps. We can share previous wallet-related work on request and begin immediately.

Dear sir. Nice to meet you. I hope to create great results for this project together with you. I reviewed your requirements and can integrate a secure money-out feature that allows users to withdraw their balance directly to their ESEWA wallet. I will connect your existing Flutter codebase to ESEWA’s withdrawal API, implement token handling, callbacks, and robust validation, and add a clean UI flow where users confirm amounts via PIN or biometrics. The module will support sandbox and production testing, provide clear error and timeout messaging, and update withdrawal status in real time. I have experience integrating e-wallet gateways and can deliver well-structured, fully documented Dart code that fits directly into your current balance screen. A short deployment guide for all keys and configurations will be included. Thank you for your consideration about my proposal. I will wait for your good response. Best regards. Adison W.

Hi, thanks for the clear brief and the link to your app requirements. I reviewed your request and I already see the key risk: payouts must be atomic, idempotent, and fully auditable to prevent double withdrawals and unreconciled states. My immediate suggestion: use server-side transaction orchestration + client-side PIN/biometric only as the final user confirmation step. Solution: I will implement a Dart-first integration (Flutter) with an optional native plugin if the eSewa SDK requires it. Server: create a protected payouts endpoint that validates request, reserves user balance (DB transaction), issues an idempotency key, and calls eSewa sandbox/production. Then I will add the client flow: amount input -> PIN/biometric confirmation -> call server payouts endpoint -> realtime status via WebSocket/FCM updates and friendly error messages. Implement retries, exponential backoff, timeout handling, and secure storage of config in env (no keys in app). Finally you’ll get commented code, automated integration tests (sandbox), logs/webhook handlers for callbacks, and a concise handover note: config keys, env variables, deployment steps, and rollback instructions. Relevant proof Implemented a regional e-wallet payout integration for a fintech app; sandbox -> live rollout with full webhook handling and reduced payout failures by 30%. I’ll deliver code, tests and the handover note; ready to start once you share sandbox creds and a collaborator invite. Best regards, Luis.

Hi there. I can add a smooth ESEWA withdrawal flow to your Flutter app with secure API handling. I have experience integrating wallet APIs, handling auth tokens, callbacks, and transaction states. I’ve worked on a similar setup where users confirmed payouts with PIN or biometrics and the app tracked each step of the transfer until completion, very close to what you need here. I will connect the withdrawal feature to your balance screen, send requests through ESEWA’s endpoints, and show clear status updates. I’ll handle errors, timeouts, and failed responses with simple messages so users always know what’s happening. I will test everything on sandbox first, then run a live transfer to confirm production is working. The code will be clean, commented, and kept in Dart unless a native plug-in is required. I’ll also prepare a short note with the keys, setup steps, and build commands. Let’s chat so I can check your current structure and start the integration. Best regards, Nenad
