Industry
FINTECH
App development for payments, investing, and crypto — where regulation is strict and security is non-negotiable. Compliance-first design to high-availability implementation.
Why Fintech
Fintech apps face unique challenges that consumer apps don't:
- Strict compliance requirements (PCI-DSS, SOC2, GDPR)
- Real-time processing and high availability (99.99%+ uptime)
- Multi-layered security (encryption, zero-trust, audit trails)
- Third-party API integrations (banks, payment gateways, KYC providers)
Approach
What I prioritize on fintech projects:
- Secure by design: threat modeling from day one
- Audit trails: immutable logging of all critical operations
- Progressive auth: biometrics, PIN, device binding
- Fault tolerance: retries and idempotency in payment flows

FAQ
What compliance standards do you follow for fintech apps?
I build with PCI-DSS, SOC2, and GDPR requirements in mind from day one. This includes encrypted data storage, audit trails, and secure authentication flows.
How long does a typical fintech MVP take to build?
Most fintech MVPs take 8–14 weeks depending on feature scope and integration complexity. Payment flows and compliance review typically add time compared to standard consumer apps.
Do you work with existing banking and payment APIs?
Yes. I have experience integrating with Stripe, Plaid, open banking APIs, and various KYC providers to connect your app with existing financial infrastructure.
What security measures do you implement?
Multi-layered security including end-to-end encryption, zero-trust architecture, device binding, biometric authentication, and immutable audit logging for all critical operations.
Can you build both web and mobile fintech apps?
Yes. I develop cross-platform mobile apps with Flutter and responsive web apps with Next.js/React, ensuring a consistent experience across all devices.
How do you handle real-time payment processing?
I design idempotent payment flows with retry logic, webhook handling, and circuit breakers to ensure reliable transaction processing even during service disruptions.
