About this Presenter
Systems Administrator since 2006 with experience in diverse industries, including education, hosting, ISPs, and finance. My expertise encompasses a wide range of areas, including DNS, MySQL, security, nginx, email (mostly postfix), scripting (Bash, PHP, Python, Perl), and large-scale log management (ELK cluster, 500+TB). I also have experience managing high-load server environments, including those supporting platforms like WordPress.com. A particular focus and passion of mine is email infrastructure, with experience ranging from user support (starting with helping in #postfix on FreeNode) to managing mail servers for a major Lithuanian provider and currently running high-volume self-hosted transactional email clusters processing 30-50 million emails daily.
