Nginx Performance Tuning & Hardening
Service description
I set up and tune Nginx so your web server stops being the bottleneck. Whether you run a busy CMS site, a Laravel or Node application, or microservices behind a single entry point, I turn a default configuration into one that is fast, predictable and secure under real traffic. I start by measuring — response times, connection handling, worker and file-descriptor limits, upstream latency and where requests actually spend their time — so every change is backed by numbers rather than guesswork.
My work covers the full production feature set. I build reverse proxy and load-balancing layers with health checks and failover, tune keepalive and buffering for your upstreams, and design caching that genuinely offloads the backend: proxy cache, microcaching, cache keys and purge strategy. On the security side I harden TLS with modern ciphers and OCSP stapling, enable HTTP/2 and HTTP/3 where it helps, add rate and connection limits, and close the misconfigurations scanners love. You get a documented, version-controlled config, before-and-after benchmarks and clear notes. I also diagnose live issues — 502/504 errors, slow TTFB, memory or CPU spikes, peak-hour failures. Typical work:
— reverse proxy and upstream load balancing with health checks;
— proxy and micro-caching to cut backend load;
— TLS hardening, HTTP/2 and HTTP/3 enablement;
— rate limiting and basic DDoS mitigation;
— bottleneck diagnosis with measured recommendations.
