I have a 10+ years of experience in systems administration in web development and e-commerce businesses. I work with linux servers (Debian, Ubuntu, CentOS) on dedicated servers, VPS servers, cloud instances (AWS, GCP, OVH, DigitalOcean) as well as on virtualization solutions like KVM/Qemu. My tools of the trade are Ansible, Terraform, Bash/Zsh, a bit of Python, PHP and other laguages, depending on the need. I also have experience as a DBA with MySQL and PostgreSQL. My webserver of choice is nginx so I can provide help with it. Others skills/technologies:
- DNS
- DKIM/DMARC/SPF (postfix)
- os/app troubleshooting and performance analysis
- data backups
- monitoring (Zabbix, Shinken/Nagios)
- Redis, MongoDB
and many others I'm familiar or can familiarise with on the project needs basis.
