About this gig

Money apps don't fail on the screens. They fail on the ledger, and you only find out after real money has already moved.


Every balance in your app has to be provable. I build the double entry ledger first, then the wallet, the payouts and the kyc on top of it, so every naira or dollar can be traced back to a single transaction record.


What you get:

  • Signup with kyc and document upload
  • Wallet balance, funding and withdrawal
  • User to user transfers with a full ledger behind them
  • Payment gateway integration with signed webhooks
  • Transaction history and downloadable receipts
  • Virtual cards and escrow holding where supported
  • Admin dashboard for users, limits and disputes
  • Fraud limits, audit logs and two factor login
  • Android and ios apps built from one codebase
  • Deployment, handover and the full source code


Tools I work with:

  • Stripe, Paystack, Flutterwave and Mono
  • Node.js, NestJS, Next.js and PostgreSQL
  • Flutter, React Native, Expo and Supabase
  • Firebase, Twilio and AWS for delivery


Tell me the country you operate in and the money flow you need, and I'll send you a written build plan for you.
