My Resume

Experience

2025 - Present
Level 3 Support - CAHL SI / Air Liquide Chile

I'm responsible for managing the company's IT resources, including server and access point maintenance. In addition to providing user support in Spanish and English, I successfully resolved a total network outage at a branch with 20 users. As the sole on-site technician, I performed diagnostics, rewiring, and configuration of a Cisco Catalyst 2960 switch with remote support in English, fully restoring connectivity.


2023 - 2025
IT Assistant - UltraPC DHC SpA

In my former role, I was in charge of managing the company's web page and database. In addition to my responsibilities, I was also required to deliver reports using Google Sheets and Power BI. I successfully completed a migration from a private server to AWS, developed a monolithic application, and implemented security measures such as iptables and other firewall protections. I worked on a project that involved creating an MVC with Python (Pandas) to communicate with the database and web page, replacing the system used that was solely reliant on Google Sheets.


2020 - 2023
Sales Assistant - Comercial ECCSA S.A

I was able to develop soft skills and communication skills. I also had the opportunity to practice my English proficiency by helping foreign customers in English.
