The challenge

The client needed a production-grade financial platform capable of handling multi-currency transactions, KYC/AML compliance workflows, crypto payment rails and complex integration requirements — built for regulated markets.

What we built

A full-stack financial product including Flutter mobile app, Vue.js web platform and a secure Node.js backend with compliance-first architecture, crypto payment rail integration and third-party financial integrations.

Compliance

  • kyc
  • aml
  • fintrac
  • audit logging
  • gdpr
  • crypto rails

Results

Multi-currency wallets with security controls built in

Multi-currency wallets with security controls built in

Users manage CAD and USD wallets with full transfer capabilities including SEPA, SWIFT and internal transfers. Security settings cover two-step authentication, payment confirmation PIN and per-user signing permissions.

  • Compliance designed into the product

    KYC/AML workflows, audit logging and FINTRAC-oriented controls were part of the architecture rather than bolted on later.

  • Full-stack FinTech delivery

    Flutter mobile, Vue.js web and a secure Node.js backend with PostgreSQL and Redis, covering wallets, exchanges and transfer flows.

  • Crypto rails inside a regulated stack

    Crypto payment rails were integrated as a payment layer alongside multi-currency wallets and signature approval workflows.
