Frequently Asked Questions
Do you handle RBI compliance and payment regulations?
I build apps that follow RBI guidelines for digital payments and data storage. This includes proper KYC flow integration, transaction audit trails, and secure data handling. For specific regulatory requirements (like payment aggregator licenses), I'll work with your compliance team to ensure the technical implementation matches legal requirements.
What are the costs for payment gateway integration?
Payment gateway setup is included in the development cost. Ongoing transaction fees depend on the provider: Razorpay charges ~2% per transaction, Stripe charges 2.9% + 30 cents internationally. UPI payments through Razorpay are free up to certain volumes. I optimize the integration to minimize failed transactions and retry costs.
How do you handle financial data privacy and security?
All financial data is encrypted at rest and in transit. I implement role-based access control, API rate limiting, and comprehensive audit logging. Sensitive data like bank account numbers are tokenized. The architecture follows OWASP security guidelines and I conduct security reviews before deployment.
Can you build an app that works offline for financial calculations?
Yes — my fintech apps use offline-first architecture with IndexedDB/Dexie for local storage. Users can access their financial data, run tax calculations, and view portfolio summaries without internet. Data syncs automatically when connectivity returns, with conflict resolution for any concurrent changes.
