High-Traffic Website Optimization & Security Enhancements

Hi,

I am looking for an experienced DevOps / Linux server optimization expert for a LIVE high-traffic production website. Please apply only if you have real experience handling 50,000+ concurrent users, Cloudflare setups, and strong security hardening.

IMPORTANT:
The website is already LIVE and fully uploaded. CyberPanel is already installed and running. I only need optimization, scaling, and security improvements (NOT fresh installation).

Current Infrastructure:
• Dedicated main server: 64GB RAM, 1TB NVMe ()
• Offshore VPS: 1GB RAM (to be used as reverse proxy/security layer)
• Domain provider:
• Panel: CyberPanel + OpenLiteSpeed (already installed)
• Laravel/PHP website (already live)
• Need full integration

My Requirements:

PERFORMANCE:
• Extremely fast loading (instant open)
• Handle 50k+ concurrent users smoothly
• OpenLiteSpeed/Nginx tuning
• PHP-FPM tuning
• MySQL/MariaDB optimization
• Redis caching
• Gzip/Brotli compression
• CDN + caching strategy
• Full performance audit

CLOUDFLARE SETUP:
• Cloudflare DNS setup
• CDN configuration
• WAF rules
• DDoS protection
• Bot protection
• Rate limiting
• Cache rules
• Hide real server IP
• Security hardening best practices

SECURITY:
• VPS as reverse proxy in front of main server
• Real IP masking of main server
• Protection from fake reports / abuse targeting
• Firewall hardening
• Fail2ban / CSF or similar
• Server hardening

ARCHITECTURE:
Cloudflare → VPS (Proxy/Firewall) → Main Dedicated Server

Main server must stay completely protected even during attacks.

TESTING:
• Load testing / stress testing after setup
• Production-ready stable configuration only

Please share:
• Similar projects experience
• Delivery time
• Fixed price quote
• Optimization plan

Only experienced DevOps engineers please. I need fast and professional work.

Thanks
