System Administrator with a solid foundation in IT infrastructure setup, optimization, and security (Linux/Windows, networking, Bash/Python automation). I possess a strong management and analytical background: I have successfully built departments from the ground up and initiated the implementation of corporate digital tools (chat systems, ticketing/request forms). I am seeking an opportunity to ensure the stable, uninterrupted, and secure operation of company servers and networks in a Junior System Administrator role.
