Project description:
"I am launching Shadow Elite Nexus as an online platform whose entire reason for existing is “Ultra Secure Whisper” communication—think hush-level data exchange wrapped in a clean, responsive web experience that works just as smoothly on mobile devices.

Security is the non-negotiable core. Beyond standard TLS, I want biometric authentication (fingerprint or facial recognition through WebAuthn / FIDO2) to gate every user action. The codebase must be written with modern encryption practices, zero-knowledge storage patterns, and strict content-security policies. I will supply brand assets; you will supply the architecture, implementation, and deployment guidance.

Key deliverables
• Responsive website coded in a mainstream stack that you can justify (e.g., [login to view URL], Django, or similar)
• Biometric login flow fully integrated and testable on major browsers and mobile OSs
• End-to-end encrypted messaging or data-sharing module that fulfils the “Whisper” requirement
• Server-side hardening scripts, audit logs, and brief documentation so another engineer can replicate the build
• Final walkthrough plus source in a private repo

Acceptance criteria
– Successful biometric authentication on at least two devices during hand-off demo
– Static and dynamic security tests pass with zero critical issues
– All features remain functional at OWASP A-rating settings

If you have a track record in high-assurance web security and can move fast without cutting corners, I’d love to see how you would tackle Shadow Elite Nexus." (client-provided description)
