Will my fintech app be secure?
Security is a priority in every build. I implement: Secure authentication (JWT / OAuth / 2FA) Encrypted data storage Role-based access control Secure transaction validation Audit logs For blockchain integrations, contracts can be deployed on networks like Ethereum, Polygon, or BNB Chain depen

Yes, I can integrate third-party KYC/KYB providers and AML monitoring APIs to support regulatory readiness.
