Description

I am a Higher Technician in Networked Computer Systems Administration (ASIR) and currently pursuing a degree in Cross-Platform Application Development (DAM). My focus is on the intersection between robust system administration and modern automation (DevOps philosophy).

I have real-world experience in deploying complex infrastructures, particularly in the design and implementation of highly available Kubernetes clusters on Proxmox VE. I am passionate about optimizing IT environments for scalability and security, using tools like Ansible for Infrastructure as Code (IaC).

Design, implementation, and complete administration of a highly available (HA) Kubernetes cluster, deployed from scratch on a Proxmox VE virtualization infrastructure. This final project represented the simulation and deployment of a real production cloud environment.

Key technical milestones achieved:

**Virtualization**: Creation and advanced management of virtual machine infrastructure (master and worker nodes), optimizing physical server resources in Proxmox.
**Networking and Security**: Implementation of a CNI (Container Network Interface) to ensure connectivity between Pods and application of strict network segmentation policies to isolate and secure environments.
**Storage**: Configuration of persistent volumes (CSI) to ensure the integrity and availability of data in critical applications.
**Automation**: Use of scripting to streamline node deployment, standardize operating system configurations, and reduce the margin for human error.

The result was a robust, fully scalable infrastructure ready to host modern applications, demonstrating problem-solving capabilities in complex systems.

During my time in the systems department at INNOVASUR, I actively participated in the administration, monitoring, and maintenance of the company's technological infrastructure.

My main responsibilities included:

Management and support of servers in Linux and Windows environments.

Network monitoring and resolution of technical incidents (Troubleshooting) at Level 1 and 2.

Support in the deployment of new services and maintenance of the virtualization architecture.

This experience allowed me to apply my ASIR knowledge in a real corporate environment, working under agile methodologies and ensuring the high availability of critical systems.
