My passion for cybersecurity is matched by my strong foundation in PKI/SSL Certificates and VPN technologies, including L2L IPsec and the AnyConnect Secure Mobility Client, alongside a broad expertise in overall VPN technologies.Expanding my horizons at IBM allowed me to delve into other firewall platforms such as Checkpoint, Palo Alto Networks, Symantec Bluecoat Proxy, and QRadar SIEM appliance. This diverse experience has honed my ability to swiftly navigate and troubleshoot in varied network environments, ensuring swift and effective resolution of complex network issues.My professional path recently took an exciting turn as I embarked on a law school journey, fueled by a strong sense of justice and a commitment to values like honesty, integrity, respect, and accountability.

Firewall EngineerIbm May 2016 - Apr 2021Costa RicaFirewall engineers design, build, and manage the security infrastructure of information technology (IT) systems. This includes installing hardware, configuring firewalls, setting up virtual private networks (VPNs), and adding upgrades. Despite the strong technical focus of the job, firewall engineers also engage with clients, relaying information about the project and troubleshooting all issues discovered. They are proficient in change management and disaster response, and they actively apply policies and standards to all projects. While they spend most of their time in front of a computer, they often function within a team of other engineers, and they may work shifts at irregular hours to perform maintenance at unobtrusive times or resolve critical issues. -
