Professional with over than 10 years of profound mastery in network engineering, system administration, and security management. As a seasoned Network Engineer/Administrator and Linux System Administrator, I've traversed a rich landscape of IT challenges, driven by a relentless passion for crafting secure and high-performing infrastructures.My journey began with network administration and engineering, where I honed my skills in configuration, design, and security, with Cisco and Extreme technologies. Leading pivotal projects, I optimized network capacity by a staggering 1,000% and orchestrated the seamless transition of physical servers to a dynamic virtualized cloud infrastructure. Proficient in WAN/LAN setups, firewall configuration, and maintaining robust network security, I've ensured that networks run smoothly and efficiently.Expanding my expertise, I delved into Linux system administration, specializing in Red Hat and Debian environments. With an extensive track record in server management, configuration, and network administration, I've navigated diverse IT landscapes with finesse. Proficient in both Linux and Windows operating systems, I've executed complex tasks with ease, from automation tools, scripting languages, backup and recovery to system configuration and maintenance. Adept at troubleshooting and problem-solving, I ensure systems run smoothly and efficiently. With strong problem-solving abilities, attention to detail, analytical thinking, and effective communication, I navigate challenges with finesse. Thriving in teamwork environments, I manage my time well, and adapt swiftly to new challenges when I have to manage new projects focused on customer service.My strength extends to virtualization technologies. In a role as Network Administrator, I led major projects, including migrating physical servers to a virtualized environment in a private cloud using VMware's ESXi Hypervisor. In this context, I initiated the replacement of existing physical servers, configuring and migrating essential services to virtual servers, which minimized the risks associated with physical infrastructure and optimized resource management. The process involved installing and configuring operating systems, transferring critical services, and conducting rigorous tests to ensure a smooth transition without disrupting customer’s daily operations. As a result, after 7 months, I implemented over 30 virtual servers, substantially reducing costs from USD 4,000.00 per physical server to USD 200.00 per month for hosting in the virtual environment.LET'S CONNECT!
