FAQ
What makes this different from a basic fintech app gig?
This gig delivers enterprise-grade architecture — immutable ledger, AML fraud detection, KYC/KYB compliance, and AI chat integration. Built for real financial operations, not just a prototype or UI demo.
Can you build multi-currency support and crypto on-ramp into one app?
Yes. I build unified fintech platforms that handle fiat multi-currency wallets and crypto on-ramp/off-ramp (Solana, ETH, BTC) in the same system with accurate decimal handling and conversion logic.
Is the system compliant with financial regulations?
The architecture includes KYC/KYB identity verification, AML transaction monitoring, GDPR-ready data handling, and audit-ready immutable ledgers. Compliance modules are configurable per jurisdiction.
Do you support multi-tenant setups for SaaS fintech platforms?
Yes. Multi-tenant support isolates wallets and data per client while sharing infrastructure. This is included in the Premium package or can be scoped as a custom add-on — message to discuss.
