Urgent DDoS Mitigation Needed

My e-commerce site Enfieldshop.ru is currently under an active DDoS attack. No protective measures are in place yet, and service interruptions are starting to hurt sales and SEO. I have full administrative access to the Nginx server, so any configuration changes or security software installs can be done immediately.

I need an experienced DDoS mitigation specialist to:

• Restore site availability quickly by filtering malicious traffic and keeping legitimate customers online
• Harden the existing Nginx stack with rate-limiting, connection throttling, and optimized firewall rules
• Configure and fine-tune an external protection layer (e.g., Cloudflare, AWS Shield, or comparable scrubbing/WAF service)
• Deliver a brief post-incident report outlining what was done, residual risks, and clear next-step recommendations

Acceptance criteria
1. Enfieldshop.ru remains reachable worldwide for at least 24 consecutive hours after mitigation is applied.
2. Server load averages fall back to normal operating levels.
3. I receive the final report and updated configuration files.

You will have root SSH access as soon as we agree on the plan. Let me know your approach, estimated timeline, and any additional information you need to get started right away.
