Summary

I started working with networks in 2015 when I was still in high school, I started in the same years to participate in it competitions in every genre from competitions programming, game creation to management or creation of entire systems eg (the management network of school students).

In 2018 I joined the municipality of Pavlos Mela as an apprentice Within 2 months became a system manager, the remaining 7 months they trusted me to build a new era in the municipality from request separation systems, recreates the internal networks of the municipality and the police up to total reconstruction of infrastructure such as (NAS, VMware ESXI / VCenter) along with them I made several automations in public processes as well as the backup of the then physical servers that existed.

Until now they still trust me as do several companies I have worked with after them.

And that's how I started , from then until now I've learned a lot , but it's still not enough and I believe it will never be enough.
