Summary

FAQs

• Can you handle complex fintech and payment systems?

  Yes, absolutely! I have extensive experience building fintech applications including VaultsPay (complete payment platform) and Burency (crypto exchange). I've implemented PCI-compliant payment processing, integrated with payment gateways like Paymentology, and built systems that handle millions of transactions daily. My expertise includes secure card management, real-time trading systems, and regulatory compliance.

• How do you ensure the application can handle high traffic and scale?

  I use microservices architecture with Redis caching and Apache Kafka for high-volume processing. My previous systems handle millions of daily notifications and real-time crypto trading. I also implement database optimization and AWS auto-scaling for peak traffic loads.

• What happens if I need changes or additional features after delivery?

  You get 30 days of free bug fixes, complete source code ownership, and a knowledge transfer session. I also offer maintenance packages at $200/month for ongoing support, and additional features can be developed at competitive rates.

• How secure will my application be, especially for sensitive data?

  Security is my priority given my fintech background. I implement end-to-end encryption using AWS KMS, JWT authentication with custom token strategies, role-based access control, and PCI DSS compliance for payment systems. I've built automated key rotation systems for maximum security.

• Can you integrate with third-party services and APIs that my business already uses?

  Yes, I have extensive integration experience with payment systems like Stripe and PayPal, communication services like Twilio, cloud services like AWS and Firebase, and business tools like CRM systems. I ensure seamless integration without disrupting your current workflows.
