I’m building a web-based portal where my clients can log in with a simple email-and-password account and immediately see how visible their site is to AI models. The core of the app is a real-time visibility score that refreshes automatically while they’re on the dashboard, so there’s no need for manual page reloads or scheduled reports. Here’s the flow I have in mind: • Secure sign-up / log-in (email + password) with best-practice hashing, optional 2FA toggle for future expansion. • An input field where a client adds or selects their domain. • Server-side process that calls the visibility-scoring engine (feel free to recommend Stack – Node/Express, Django, or another modern framework is fine) and streams the latest score back through WebSockets or Server-Sent Events. • A single-page dashboard that displays the live score, last-updated timestamp, and a short “what changed” note. • Admin area for me to add, suspend, or delete client accounts and adjust any API keys used in the scoring logic. Deliverables 1. Source code in a private repo with clear setup instructions. 2. Deployed staging instance (Vercel, Netlify, or my own VPS) so I can test with real domains. 3. Brief hand-off video or call walking me through the code, deploy steps, and how to add new clients. Acceptance criteria – Client can register, confirm email, and log in. – Dashboard loads the visibility score within two seconds and updates in real time. – Admin panel actions reflect immediately (e.g., disabling a user blocks access on next request). – Code passes a basic security audit (no plain-text passwords, CSRF protected, etc.). If this sounds like a fit, let me know which tech stack you’d choose and roughly how long you’d need for an MVP.
