Fintech / Payroll / Crypto
We build fintech systems where money accuracy is non-negotiable: payroll, payouts, wallets, payment rails and crypto-enabled flows.
Features
- Payments, payroll and payouts.
- Crypto payroll and token payout flows.
- Wallet and transaction workflows.
- KYC, compliance and reporting.
Engineering principles
- Idempotency and reconciliation as a foundation; every payout traceable and replayable for audit.
- Validated webhooks; compliance built into the flow.
Stack
Node.js · PostgreSQL · integrations (Stripe, Mercado Pago, Payoneer) · blockchain-aware infrastructure.
Considerations
- Never hardcode keys; use environment variables and secret management.
- Validate webhooks, keep audit, and never log sensitive data.
