Common questions about fintech development services

How do you handle PCI compliance?

We implement PCI DSS Level 1 compliant architectures using tokenization, encryption at rest and in transit, secure key management, network segmentation, and regular security audits. We use certified payment processors like Stripe for card handling, ensuring sensitive data never touches your servers directly.

Can you build neobank apps?

Yes, we specialize in digital banking solutions including account opening, KYC verification, debit card issuance, P2P transfers, bill payments, savings accounts, and spending analytics. We integrate with banking-as-a-service platforms like Synapse, Unit, or Treasury Prime for core banking infrastructure.

What payment processors do you integrate?

We have extensive experience with Stripe, PayPal, Square, Adyen, Braintree, Authorize.net, Plaid for ACH, Dwolla for bank transfers, and international processors like Razorpay, Mollie, and Checkout.com. We can also build custom payment gateway integrations for specific regional or business requirements.

How do you handle real-time trading?

We build low-latency trading systems using WebSocket connections for real-time market data, order book management with optimized data structures, event-driven architectures with message queues, and in-memory caching for sub-millisecond response times. We integrate with broker APIs like Alpaca, Interactive Brokers, or TD Ameritrade.
