Software Engineering for Fintech & Payments
Build compliant, secure, and lightning-fast financial products with a dedicated engineering team that understands regulatory nuances across Vietnam, Singapore, the EU, and the US.
The Challenges We Solve
We have worked across dozens of fintech & payments projects. These are the pain points we hear most, and know how to fix.
Regulatory compliance (PCI DSS, KYC/AML, GDPR) slows time-to-market
High transaction volumes demand sub-second latency at scale
Security vulnerabilities expose customer data and breach trust
Legacy core banking integration is complex and risky
Fraud detection requires real-time ML pipelines that most dev shops cannot build
Our Fintech & Payments Solutions
From product strategy to production deployment, our dedicated teams cover the full engineering lifecycle.
Payment Gateway & Wallet Engineering
End-to-end payment flow design, from front-end checkout to back-end settlement. We build wallets, peer-to-peer transfer systems, and payment gateway integrations with Stripe, Adyen, VNPay, and regional payment rails.
KYC / AML Compliance Systems
Automated customer identity verification, PEP screening, sanctions list checks, and transaction monitoring pipelines. We integrate leading providers (Onfido, Jumio, ComplyAdvantage) and build custom rule engines for your regulatory jurisdiction.
Trading Platforms & Dashboards
Real-time market data feeds, order management systems, portfolio dashboards, and trade analytics. Built with WebSocket streaming and sub-100ms latency on highly available cloud infrastructure.
Lending & Credit Platforms
Loan origination systems, credit scoring integration (alternative data, bureau APIs), loan servicing automation, and collections management, built to handle thousands of simultaneous applications.
PCI DSS, KYC/AML & Open Banking
Our fintech teams hold PCI DSS knowledge across card-present and card-not-present environments. We implement compliance from architecture design, not as a retrofit.
PCI DSS Level 1 compliant card data handling (tokenisation, encrypted storage)
KYC/AML pipelines with automated PEP screening and sanctions list checks
Open Banking API integration (UK FCA PSD2, MAS SGQR, Vietnam NHNN regulations)
GDPR / PDPA data residency and consent management
3DS2 strong customer authentication flows
