Nicolás Gallia

Hello, I'm Nicolas Gallia. I'm a computer engineer with a strong background in security, systems administration, and infrastructure support.

I currently work in the systems department at one of the largest research centers in Argentina, and I also teach databases and networks at a national university. I'm known for being calm, methodical, and detail-oriented when providing solutions.

At the moment, My main tasks are optimizing and maintaining the networks, the email system, and several on-premises servers. However, since we're a small team, we also frequently perform various tasks such as development, database administration, and user support. We have a high degree of autonomy and make the decisions and implement the systems we deem necessary on our own.

Previously, I held various security and compliance roles, where I coordinated audits and led a team that performed vulnerability analysis and subsequent remediation at the operating system level.
