Secure fintech development
Payment systems, banking apps, and financial platforms built with security-first engineering practices by senior offshore developers. Compliance-aware from day one.
Why fintech is different
Security is non-negotiable
Financial applications handle sensitive data - account numbers, SSNs, transaction histories. A single breach destroys customer trust and triggers regulatory penalties. Security can't be bolted on after launch.
Compliance complexity
PCI-DSS for payments, SOC 2 for data handling, KYC/AML for onboarding, and state-specific money transmitter licenses. Every feature decision has compliance implications that your engineers need to understand.
Real-time processing demands
Transactions must process in milliseconds. Balance checks, fraud detection, and authorization decisions happen in real time. Latency isn't just a UX problem - it's a business-critical requirement.
Integration complexity
Banking APIs, payment processors, credit bureaus, and identity verification services all have different protocols, rate limits, and failure modes. Building reliable integrations requires experience with financial system quirks.
How we build fintech products
Security-first architecture
Encrypted data at rest and in transit, parameterized queries, input validation on every endpoint, rate limiting, and WAF rules. IAM policies follow least-privilege principles. Secrets managed through AWS Secrets Manager or HashiCorp Vault - never hardcoded.
PCI-DSS compliant payment systems
Tokenized card storage, secure payment processing with Stripe or Adyen, webhook verification, and idempotent transaction handling. We architect payment flows that keep sensitive card data out of your systems entirely.
KYC/AML workflow automation
Identity verification integrations with Plaid, Jumio, or Onfido. Automated document verification, sanctions screening, and risk scoring. Compliance workflows that onboard legitimate customers fast while catching fraud.
Real-time transaction monitoring
Event-driven architectures that process transactions in real time. Fraud detection rules, velocity checks, and anomaly detection. Alert systems that flag suspicious activity before it becomes a loss.
