I will build bill payment, airtime and utility payment app


About this gig
Building a payment app is not just about creating screens and connecting a payment API.
The real challenge is making sure the entire payment experience works correctly when a user funds a wallet, purchases airtime, pays a utility bill, receives a transaction response, gets a receipt, or experiences a failed or pending transaction.
I develop bill payment, airtime, data recharge, utility payment, VTU, wallet and fintech applications with the goal of creating a simple, reliable and scalable payment experience for both users and administrators. Many payment applications look good but become difficult to manage when real transactions start happening.
- A user may be charged while the service remains pending.
- A transaction may fail but the wallet balance may not update correctly.
- An API may return a delayed response.
- A payment may be submitted twice.
- A utility customer number may need validation before payment.
- An administrator may not have enough information to reconcile transactions.
These are the types of problems that need to be considered when building a serious payment platform.
