I'm Juan David Ferrer

Second-grade high school student and systems administration enthusiast with a rigorous focus on Linux infrastructure and technological sovereignty. I am focusing my professional development toward specializing in the deployment of critical services, kernel-level optimization, and advanced hardware maintenance

Founder of HandDesk Linux (currently on hiatus), a project dedicated to Debian-based optimization and custom desktop environments for legacy hardware. My technical workflow is built around RHEL 9.7, utilizing SELinux, LVM storage management, and network hardening to ensure high-availability environments.

Currently advancing towards EX200 (RHCSA) and EX294 (RHCE) certifications, applying enterprise-grade standards in bare-metal labs. I prioritize open-source efficiency and security-first architectures as the foundation for future scalable infrastructure.
