I will build your fintech app in flutter with secure banking api integration


About this gig
Need a finance or fintech app that actually connects to real bank data not just a UI mockup?
I'm a Flutter developer who builds full-stack financial apps, including real banking API integration using Plaid, so your app can securely pull real account balances, transactions, and net worth data.
What I offer:
- Cross-platform finance apps (Android, iOS, Web) built with Flutter
- Secure backend using Node.js REST APIs, authentication, data handling
- Real banking data integration via Plaid (account linking, balances, transactions)
- Budgeting, expense tracking, net worth, or investment-tracking features
- Firebase or custom backend for user auth and data storage
- Clean, secure, well-documented code financial apps get built carefully, not quickly
My process:
- We lock down scope and which financial features/data you need before I start
- UI build first, shared with you for feedback
- Backend + Plaid/API integration and testing
- Security review pass, then final delivery with source code and a walkthrough
Message me before ordering financial apps vary a lot in scope, and I'd rather quote it accurately than guess.

FAQ
Do you connect to real bank accounts
Yes, via Plaid, which securely links to thousands of banks without me ever seeing raw banking credentials.
Is my users' financial data secure?
Yes — token-based auth, encrypted storage, and Plaid handles the sensitive bank-connection layer directly, so raw credentials never pass through my code.
Do you build the backend too?
Yes, full-stack: Flutter frontend plus Node.js or Firebase backend.
Does this work for budgeting apps, expense trackers, or investment trackers?
Yes, the same core setup (Flutter + secure banking API) fits any personal-finance use case.
