About Perruche

I am a passionate Network & Load Balancer Engineer specializing in F5 BIG-IP, HAProxy, Citrix networking, and infrastructure automation with Ansible.
I also have solid experience in monitoring (Prometheus, Grafana), SSL/TLS certificate management, and network security.

As a freelance engineer, I help companies optimize their network infrastructure through:
• Audits & optimizations of load-balancer configurations
• Scripted automation (e.g., renewals of SSL certs, deployment workflows)
• Monitoring setup and alerting (SSL certificate alerts, performance dashboards)
• On-demand support and incident troubleshooting
