About this gig

Your fintech app needs more than good screens. Payments, wallet balances, KYC, and transaction states must work correctly.


I can build or complete the core flows so users can fund, send, receive, verify, and track money with confidence.


Fintech projects often break where the app meets payment APIs, identity checks, webhooks, or backend logic. I connect those parts carefully and make each state clear to the user.


What you get:

  • Wallet and balance flows
  • Payment gateway integration
  • KYC and identity checks
  • Beneficiary management
  • Transaction history
  • Webhook and status handling
  • OTP and secure login
  • Push notification flows
  • API and backend integration
  • Testing and handoff notes


Tools I work with:

  • Flutter, React Native, Node.js
  • Stripe, Plaid, Paystack, Flutterwave
  • Supabase, Firebase, PostgreSQL
  • REST APIs, webhooks, KYC services


Send your screens, API docs, current code, and required payment flow. I will map the blockers and build the parts needed for a secure, usable fintech app.


Your final system will be easier to test and extend when new countries, providers, or payment methods are added.
