Frontend security

Security is treated as a systemic property. The objective is measurable risk reduction without compromising delivery. I authored a company-wide threat vector document - 20+ attack types across a live platform, a concrete mitigation for each - and drove implementation across code and infrastructure.

Mechanisms:

• Secure-by-default rendering, reducing XSS exposure.
• CSRF-aware flows with explicit session boundaries.
• Cryptographic signature verification for sensitive requests.
• Dependency risk management and supply chain hygiene.

Infrastructure:

• Domain allowlists enforced at the edge.
• Request validation before business logic execution.
• Decision-making supported by metrics and audit logs.
