Fintech App Development FAQ

How do you handle PCI-DSS compliance in fintech apps?+
I never store raw card data in your app. Instead, I use tokenization through PCI-compliant payment processors like Stripe. All sensitive data is encrypted, and I implement secure API design patterns that meet PCI-DSS requirements.
How much does fintech app development cost?+
Fintech apps vary widely in cost. A simple payment or budgeting app starts at my Professional plan level. Complex apps with trading, banking features, or multi-currency support typically need an Enterprise plan. Monthly subscriptions let you start with an MVP and grow.
Can you integrate with banking APIs and payment processors?+
Yes, I work with Plaid for bank account linking, Stripe and Square for payments, and various market data APIs for investment features. I also integrate KYC providers like Onfido or Jumio for identity verification.
How long does it take to build a fintech app?+
A fintech MVP typically takes 10-14 weeks due to the additional security and compliance requirements. Simple payment apps may be faster at 8-10 weeks, while full neobank platforms can take 16+ weeks.
Do you build cryptocurrency and blockchain apps?+
Yes, I build crypto wallet apps, portfolio trackers, and DeFi interfaces. I integrate with major blockchain networks and can implement features like token swaps, staking, and NFT displays.
What about KYC and identity verification?+
I integrate KYC/AML verification into the onboarding flow using providers like Onfido, Jumio, or Sumsub. This includes document verification, facial recognition, and sanctions screening to meet regulatory requirements.
