⚠️!!NB!! ⚠️ YOU NAME THE PRICE — I’LL DOUBLE THE IMPACT Hey Zozoman! Elevate your website security with a backend that’s impenetrable. By migrating to Node.js on Ubuntu 24 with MySQL integration, I'll tighten your security bolts and implement user-friendly management. A few reviews? That’s your edge. While others coast, I’m hungrier. This project isn’t just work — it’s my statement. Your success is my reputation. Off-platform, my expertise in MySQL and secure backend architecture stands strong. Let’s chat more about your project! Regards, Casper

I see your concern — exposing API keys and DB details in the browser is a serious security risk that leaves your app vulnerable. I can help you migrate to a secure Node.js backend with Express and MySQL on Ubuntu 24 while keeping all current features intact. Here’s how I’ll approach it: Move all sensitive logic and API keys from the frontend into a protected backend. Build a session-based authentication system using secure cookies and MySQL as the session store (with bcrypt for password hashing). Implement full user management (register, login, password reset, profile management). Apply strong security hardening: helmet, rate limiting, CSRF protection, strict CORS, secure cookie flags, and environment-based secret management. Deliver a clean REST API for your React frontend to consume, ensuring smooth integration. Provide deployment guidance on Ubuntu 24: HTTPS setup, systemd service, and firewall basics. Handover includes schema/migration scripts, integration notes, and a short guide so you can manage updates. I’ve built secure backends for React apps and SaaS platforms where moving secrets server-side was critical. This will give you a stable, secure, production-ready backend with all sensitive data protected. Can you share your current repo or a sample build so I can review the exposures and prepare the migration plan?
