I will secure your backend systems and APIs with a comprehensive API security audit, threat modeling, and remediation plan, then implement hardened logic, authentication, and authorization layers that prevent abuse, protect sensitive data, and pass compliance checks (HIPAA, SOC2, GDPR, PCI-DSS).
Whether you’re running a FastAPI or Flask backend, or integrating 3rd-party APIs, I will identify vulnerabilities, enforce secure design patterns, and deliver enterprise-grade fixes using OAuth2, JWT, RBAC, token revocation, rate limiting, IP whitelisting, and request validation.
This is not surface-level — it’s infrastructure-level hardening from a red team-trained backend expert.
