As a senior linux system administrator with over 15 years of experience, I possess a wealth of knowledge and expertise in all aspects of Linux server administration, configuration, and management. I have different certifications from Udemy, Cisco Networking Academy, AWS and cPanel. I have honed my skills over the years and I am well-versed in using various tools and technologies related to Linux, including Ansible, DigitalOcean, AWS, and cPanel. My extensive experience in Linux system administration has allowed me to develop an in-depth understanding of how Linux servers work and how to optimize their performance to meet business needs. I am proficient in installing, configuring, and managing various Linux distributions and have a solid understanding of networking, security, and server management concepts. In addition to my daily job as a Linux system administrator, I also take freelance projects in my free time. I'm always looking for new challenges and opportunities to expand my knowledge and skills, and I stay up-to-date with the latest developments in Linux and related technologies. Technologies I'm familiar with: CentOS, Redhat, Ubuntu, Debian, Postfix, MySQL, MariaDB, Apache, Nginx, Varnish, Haproxy, Iptables, Zabbix, Nagios, Cacti, Icinga2, Grafana, Elasticsearch, Kibana, Docker, Kubernetes, Odoo, CWP, VestaCP, Plesk, cPanel, Virtualmin, Proxmox, Opennebula. Overall, I am a highly skilled and experienced Linux system administrator who is committed to delivering top-quality services to clients and ensuring the smooth and efficient operation of Linux servers.

Odoo 15 DevOps Dynamo $78 USD

The admin did his job, but he was extremely stingy and negative. He got angry because I asked hime to restore both DBs to the Odoo installation when it was only showing one. He disappeared so I had to nudge him to finalise. I had to remove one task since I did not like his attitude. He could not move the NDA server so he immediately started questioning if it ever had worked. I have also asked for an issue with known hosts, that stopped working. He went in and destroyed all. I am now in a mess
