I'm a proficient Linux SysAdmin, and still voluntarily manage two on-site servers at my college. One of my implementations: A High availability setup for serving thousands of concurrent users in a second: used the following stack, Nginx LoadBalancer, Nginx Web servers, PostgreSQL servers, Memcached and Redis. Every server with RAID backups. I love experimenting with severs and have vast experience with these providers: AWS, Google Cloud Compute, DigitalOcean, Vultr, Linode. I have worked on following Panels: cPanel and WHM, VestaCP, Zpanel, Custom management Scrips, sever setup without any panel. I have great command on Command line interface. My default OS is Linux.
