Yes, I can take this on. I’ve worked extensively with PHP systems that involve OAuth, third-party APIs, search logic, and admin security, so this scope is very familiar. I’ll fix the Gmail OAuth and login flow (redirect URIs, token expiry, sessions) and properly integrate the Gemini API with sensible error handling and fallback so it doesn’t break production. On the frontend, I’ll clean up the contrast issues, fix the responsive slider bug, and update the menu structure exactly as described. The search and filters will be repaired end-to-end (API + SQL), with proper indexing and clean empty states. I’ll also redesign the homepage based on your reference, keeping it fast, responsive, and SEO-friendly. On the backend, I’ll build a modular supplier API with a normalized database, clear sync rules, and comparison between manual vs supplier data. The distributor API will be secured using JWT/API keys, rate limits, and logging. Admin security will be upgraded with 2FA, roles, and proper password hashing (bcrypt/Argon2).
