FinTech startups, crypto on-ramps, real-estate crowdfunding portals, and regulated marketplaces onboarding users globally frequently search to hire a freelance KYC, KYB & AML compliance integration (Persona, Stripe Identity, Sumsub, Onfido, Middesk, Alloy) programmer. I am Aldian Fazrihady, a Senior Freelance Full Stack Developer and FinTech Security Engineer.

Core KYC/KYB Onboarding & Risk State Machine Capabilities

  • Frictionless Identity Verification Flows: Integrating government ID liveness checks, biometric selfie matching, and business registry (KYB) verification via Persona, Stripe Identity, Sumsub, and Middesk in React and React Native.
  • Sanctions, PEP & Adverse Media Screening: Automating OFAC/UN/EU sanctions screening and ongoing webhook monitoring with deterministic case-management queues for compliance officers.
  • Zero-Leak PII Encryption & Vaulting: Storing verification statuses and cryptographic tokens without exposing raw passport/SSN images in application databases.

Frequently Asked Questions

How do you handle asynchronous KYC manual review webhooks cleanly?

I implement a strict state machine (`PENDING_SUBMISSION -> IN_REVIEW -> APPROVED | REQUIRES_RETRY | REJECTED`) driven by signed webhooks, with real-time WebSocket/SSE UI updates so approved users unlock platform features immediately.
