Network Migration - Migration of the network of an Internet service provider that was found with a topology totally in Bridge mode (layer 2) and without any type of redundancy for a multi-area routed network with OSPF, thus dividing the broadcast domains in order to take advantage of better the capacity of the network to transmit data and making it more secure by using redundant links and routes to be less subject to failure. In addition, MPLS was implemented and bottlenecks were eliminated in order to not only offer a better Internet service, but also offer VoIP, TVIP and CCTV services with the same data network. This project contributed to the growth of the company by being able to expand into new businesses using the infrastructure they already had.
EtherdogsC - Development of an 802.3 network sniffer using the PCAP library of the C programming language, together with an international team of programmers which I led during the three months of development of this open source tool for GNU/Linux systems.
MK-Log - Development of a connection logging system for Mikrotik's RouterOS system, built from scratch on a GNU/Linux operating system with technologies such as PHP, Twitter Bootstrap, MySQL and Syslog-ng. The objective of this system was to offer a robust and intuitive solution for logging Internet service provider connections via RF.
