Authentication & Security
I architect zero-trust security models that safeguard your systems from modern threats while maintaining seamless user experiences. My approach combines defense-in-depth strategies with pragmatic implementation, covering identity management, data protection, and infrastructure hardening. From OAuth 2.0 flows to cryptographic best practices, I ensure compliance with GDPR, HIPAA, and SOC2 requirements while preventing breaches before they happen.
Development Services
Advanced Authentication Systems
Implement passwordless auth, multi-factor, and step-up authentication with tools like Auth0, Okta, or custom solutions. Balance security with UX through adaptive authentication rules.
Authorization & RBAC/ABAC
Design fine-grained access control using role-based or attribute-based policies. Enforce permissions at API, UI, and data layers with Open Policy Agent or Casbin.
Session Management & JWT Security
Secure token-based auth with short-lived JWTs, refresh token rotation, and strict validation. Mitigate risks like token replay, CSRF, and session fixation with encryption and storage best practices.
Secrets Management & Encryption
Rotate and inject secrets securely using Vault, AWS KMS, or Azure Key Vault. Implement end-to-end encryption for data at rest and in transit.
Threat Detection & Hardening
Deploy WAF rules, bot detection, and runtime protection against OWASP Top 10 vulnerabilities. Automate DDoS mitigation with Cloudflare or AWS Shield.
Compliance & Audit Logging
Generate immutable audit trails for all auth events. Prepare for audits with automated compliance checks and data sovereignty enforcement.
Benefits
Defense-in-Depth Security
Layer network, application, and data-level protections to ensure breaches are contained. Regular penetration testing identifies gaps before attackers do.
Future-Proof Compliance
Pre-built templates for GDPR, CCPA, and HIPAA reduce legal risk. Automated token revocation and consent management simplify regulatory adherence.
High-Availability Auth
Geo-redundant auth clusters with failover support ensure logins work even during outages. No single point of failure in critical flows.
Performance-Optimized
Stateless JWT auth reduces database load. Edge caching of auth policies minimizes latency for global users.
Development Process
Threat Modeling & Requirements
Identify assets, attack vectors, and compliance needs via STRIDE analysis. Define auth flows, token lifetimes, and crypto standards.
Architecture Design
Select auth protocols and tools. Plan key rotation, disaster recovery, and monitoring for all security components.
Implementation & Testing
Code auth logic with fuzz testing and SAST tools. Verify session hijacking resistance via automated exploit simulations.
Deployment & Monitoring
Roll out with dark launch capabilities. Monitor failed logins, token abuse, and anomaly detection with SIEM integration.
