Server Administration
Infrastructure work
End-to-end server ownership.
Provisioning & OS
- Production Linux environments across AlmaLinux, Ubuntu, and Debian distributions
- Bare-metal and VPS provisioning with security-hardened baseline configurations
- SSH key infrastructure, role-based access control, and firewall policy management
- Automated cron orchestration, environment variable governance, and secrets management
- Server and platform migration planning and execution
Web Servers
- Nginx — reverse proxy architecture, SSL termination, SPA routing, and load distribution
- Apache 2.4 — virtual host management, Brotli compression, ProxyPass configuration
- LiteSpeed on cPanel environments with custom SPA deep-link resolution
- Advanced proxy configurations for streaming, embedded content, and cross-origin policies
Process Management
- PM2 for Node.js/Express process orchestration with environment-aware restarts
- Supervisor-managed Laravel queue workers with concurrency tuning and saturation analysis
- Resource profiling and worker optimization to eliminate CPU/memory bottlenecks
- Zero-downtime deployment pipelines with structured rollback procedures
SSL & DNS
- Let's Encrypt certificate lifecycle management with automated renewal pipelines
- Cloudflare proxied DNS, SSL termination, WAF policies, and DDoS mitigation
- Multi-domain and multi-server certificate orchestration
- DNS record architecture across Cloudflare and authoritative nameservers
Performance Tuning
- Brotli/gzip compression tuning at the web server layer for measurable latency reduction
- Immutable asset caching strategies with long-lived Cache-Control and fingerprinting
- JavaScript bundle optimisation — route-level code splitting reducing payloads by 80%
- PHP-FPM pool tuning, opcache configuration, and database query optimisation
Diagnostics & Backup
- Root-cause analysis of memory exhaustion, application errors, and performance degradation
- System monitoring — load averages, disk I/O, memory pressure, and log analysis
- Automated backup infrastructure with off-site cloud sync and configurable retention
- Production incident response: debugging, triage, and remediation workflows
