Education
Universidade Metodista de Piracicaba
Higher Diploma in Network Computer (NFQ Level 6)

​2007 - 2010

 

At the end of the college course, my classmates and I, planned a real network design for a large hospital of the region. 

This project aimed to solve the problem of monitoring and managing the network of the client, Hospital Irmandade da Santa Casa de Misericórdia de Piracicaba.

Due to the large amount of network-connected devices, their management became more difficult, more time consuming to detect potential problems and bottlenecks within the same. 

Anxious to solve the problem presented, we propose some solutions using open source services, such as CACTI, MRTG, NTOP and NAGIOS.
