I've been working as a SysAdmin since 2002 and I can distinguish three stages in my carrer:

   * The 'internship years': 2002 to 2008, there was several internships in different departments of my

   university (UNSa) and in the provincial goverment social security company (IPS). Those jobs where more

   end-user tech support, but I took my first steps setting up and managing linux servers, mostly

   fileservers (with smb and nfs) and webservers (apache)

   * an "everything-ologist" SysAdmin at another university (UCASAL): 2008 to 2022 There I had some end-user

   support tasks, but there I and a couple of coworkers were in charge of the IT infrastructure. I started

   with 6 or 7 PC acting as servers (for the website, e-learning, library and internal use systems,

   fileservers, dns, etc) and router/firewall. When I left the job we had about 150 virtual machines running

   on top of VMWare ESXi and real server hardware. Our main OS always was FreeBSD, but we also had several

   linux (oracle, debian, centos and ubuntu), solaris (for zfs storage), and windows. Some of the tools we

   used to work with were Apache, Nginx, PHP, PostgreSQL, MySQL (for internal use our main DB was oracle, but

   there where DBAs for manage oracle); Dovecot and Postfix for mail (then migrated to google), SMB, NFS,

   ZFS; Tomcat, Tomee, Weblogic; Pfsense, mikrotik, cisco, etc.

   * Specialized Linux SysAdmin at Donweb.com: since nov 2022. When I left the university I took a job at a

   large hosting company in Argentina. Now I'm a full SysAdmin with no end-user support tasks. My team are in

   charge of the linux servers of the company, with heavy focus on the shared hosting servers. Inside my team,

   I with a coworker are a kind of informal DBAs (since there isn't a DBA position), and take care of the MySQL

   servers, both "regular" replicated MySQL and some Galera clusters.

Also, during the quarrantine I began to took some small sysadmin jobs or tasks as a freelancer
