FAQ
What technologies do you use to build the fintech solution?
I use a modern, scalable stack including TypeScript, Node.js, PostgreSQL, and AWS serverless services. This ensures high availability, performance, and cost-efficiency for financial-grade applications
Is the wallet solution secure and compliant?
Yes. The wallet module uses an immutable ledger design to ensure every transaction is traceable and tamper-proof. Security best practices (encrypted data at rest/in-transit, JWT tokens, IAM roles) are baked in. For compliance-heavy environments, I can support KYC/AML add-ons
Can I integrate this with my existing system or mobile app?
Absolutely. All modules are API-first and come with Swagger/OpenAPI documentation for easy integration. I can also help align the system with your frontend or third-party platforms
Do you support multiple currencies or multi-tenant setups?
Yes, these can be added as extras or scoped in a custom offer. Multi-currency support includes currency conversion logic and accurate decimal handling. Multi-tenant support enables isolated wallets and transactions per client or user group
Will I get the full source code?
Yes. You will receive clean, well-documented, production-ready code that you fully own
Can I request a custom feature that’s not listed in the package?
Yes — I welcome custom requirements like scheduled payouts, custom transaction types, or compliance logic. Just send me your use case and I’ll provide a tailored offer.
