I am writing to introduce myself as Pablo Jesús Plaza Medina, an enthusiastic systems administrator with expertise in deployment, automation, and project development. My specialization lies in virtualization environments, containers, and the development of new systems and networks. Throughout my career, I have gained extensive experience in planning and developing interoperable WAN networks, as well as implementing semi-autonomous software deployment and service deployment systems. Currently, I am undergoing Professional Training as a Network Systems Administrator, which I combine with freelance work. Companies have primarily chosen me for my expertise in Docker services and networks, providing me with an opportunity to acquire in-depth knowledge of Kubernetes in both cloud and on-premises environments. During this period, I have successfully deployed load-balanced and replicated services across multiple locations, ensuring 99% availability autonomously. Additionally, at my educational institution, I lead a project with fellow students to set up two nodes in Proxmox to manage intranet services for our class. In this project, I have handled workload management, failover rules, networking, and service security, using cutting-edge technologies such as Docker and Kubernetes, all under Proxys functionality. I would like to offer my services as a Systems Administrator and Infrastructure Manager, leveraging my extensive experience and expertise in microservices. This enables me to deploy multiple systems efficiently and consecutively within a short timeframe, enriching my knowledge through the challenges your company might provide. I wish to emphasize my immediate availability, as well as my willingness to undertake deployments or overnight shifts, if necessary. I appreciate your attention and look forward to the opportunity to discuss in more detail how I can contribute to your company.

Desde el primer día, asumí la responsabilidad del soporte de tercer nivel para asuntos operativos de conectividad y el desarrollo de proyectos de ingeniería de seguridad. Mi objetivo era claro: garantizar la integridad y eficiencia de las infraestructuras de IT y alinear estos proyectos con los objetivos estratégicos de la empresa y sus clientes. Recuerdo ocasiones en las que nuestra infraestructura enfrentaba problemas de conectividad críticos. En esos momentos, formar un equipo interdisciplinario y aplicar nuestra experiencia en tecnologías avanzadas como Fortinet, Palo Alto, FortiManager, Panorama y VPN Box, junto con herramientas como FortiAnalyzer, FireMon y Splunk, fue crucial.
