O mnie

Senior Fullstack Engineer | FinTech, Healthcare, Insurance | KYC, GDPR, CCPA, HIPAA

I’m a Senior Full-Stack Engineer with 10+ years of experience building secure, compliant, and scalable products across FinTech, Healthcare, and Insurance. I specialize in end‑to‑end delivery—from architecture and APIs to front-end UX—while meeting stringent regulatory and data privacy requirements including KYC/AML, GDPR, CCPA, and HIPAA.

What I deliver:

· Secure, compliant platforms: Identity verification (KYC/AML), consent management, audit trails, data retention policies, PHI/PII encryption, role-based access control

· High-performance web apps and microservices: Low-latency APIs, event-driven architectures, robust CI/CD, automated testing

· Cloud-native solutions: Kubernetes, Docker, Terraform, AWS/GCP/Azure best practices, observability (metrics, logs, tracing)

· Enterprise-grade integrations: Payment gateways, core banking, EHR/EMR, insurance carriers, CRMs, analytics, and messaging systems
