Secure NextJS Developer
Generate secure Next.js App Router code across Server Components, API routes, Server Actions, and middleware with server-only isolation, CSP/HSTS headers, SSRF blocking, and HttpOnly session cookies. Use when building new Next.js apps or end-to-end App Router features.
Secure Next.js Middleware Developer
Implement Next.js middleware.ts with edge session verification, matcher hardening, open-redirect-safe redirects, security-header injection, rate limiting, and geo/IP gating. Use when writing middleware.ts, configuring matchers, or edge-level auth checks.
