In this module, on the first year, we got to know different softwares and applications (for example, text-editing applications),
operating systems, and computer networks.
My computer network on Cisco Packet Tracer (November 2023)
Planning IP addresses (January 2024)
Windows task (November 2023)
macOS task (November 2023)

In this module, we study programming. On the first year, we got to know different
numeral systems (binary, octal, decimal, and hexadecimal system), truth tables, and studied programming
in Python. I completed the programming tasks shared with us by the teacher in lahendus.ut.ee.
I also made a project: a game where you have to guess Estonian proverbs - a simple game based
on the hanging game.
Half way through the semester, we got a new programming teacher. In addition to programming,
the new teacher taught us how to use GitHub through Linux command line. As a sample project,
according to the instructions, we made a game called Bubble Blaster - a 2D game where the player controls a red box and has to
catch as many bubbles as possible.
As a group project, I created a 2D game called Super Mario Plane - a retro-style game where the player controls Super Mario and has to collect coins while avoiding enemies - with two other students (GitHub link).

In this module, we study client device management: for example, we have installed antiviruses to computers, and we have learned to use some client management softwares to get information about devices on the network (e.g. SpiceWorks and OCS Inventory). Here you can see the OCS Inventory installation guide, created as a task.
OCS Inventory task (September 2024)
Landscape task on Ubuntu (September 2024)
Windows Server Update Service task (September 2024)
Cloning a virtual machine using DISM (November 2024)
In this module, we learn how to install and manage Windows operating systems. We have created a network made of virtual machines for a virtual company called Mukri, and then we created yet another virtual network independently.
FreeNAS task (October 2024)
Making a router for the virtual network (October 2024)
Configuring DHCP for the virtual network (October 2024)
Creating organisational units (November 2024)
Creating a file server (November 2024)
In this module, we learn how to create and manage networks, and how to configure network devices and firewalls. We have learned network management, both virtually on Cisco Packet Tracer and physically in the lab.

Configuration management using LibreNMS and Oxidized (May 2025)
In this module, we study different Linux/BSD-based operating systems. Similarly to the Windows module, we create a local area network with our own infrastructure in this module as well, using an OPNsense virtual router and Linux virtual servers.
Proxmox task (March 2025). I use Proxmox hypervisor for creating virtual machines.
TrueNAS task (March 2025). I use TrueNAS storage for virtual machines on Proxmox.
Apache web server on Debian (March 2025)
Observium monitoring server (March 2025)
In this module, we study different ways of hosting, as well as hardware (e.g. servers).
Connecting MinIO and NextCloud (January 2025)
Configuring an iSCSI target server and an initiator (February 2025)
In March 2025, I participated in VOCO's competition called Aasta Tegija 2025, and I got the 8th place out of 22. The task was to solve 15 tickets where users were complaining about some problems with their computers and systems. I managed to solve a problem where the user couldn't log in due to not remembering their password (both on Ubuntu, as well as on Windows), as well as a problem with Debian GUI.
