What I'm looking for

I’m looking for remote-friendly work where I can combine IT support with security-minded automation—troubleshooting users, hardening systems, and shipping reliable tools that are auditable and maintainable.

I’m an IT Support Intern in Asturias, Spain, and a Technician in Microcomputer Systems and Networks (Intermediate VET). I troubleshoot workstations, peripherals, and network issues while supporting day-to-day office operations, and I work with both Windows and Linux systems to keep users moving.

I also build security-minded tooling through personal projects: a Go MCP security gateway with API-key auth, role-based access control, Redis rate limiting, and PostgreSQL audit logging; and a Windows 11 hardening menu designed to make changes auditable, reversible, and transparent. Beyond security, I’ve shipped automation and web tooling—like an OpenCode MCP configuration GUI and GitHub PR/issue review workflows—so I can turn repeatable processes into dependable systems.
