What I'm looking for

I'm looking for a technical support or helpdesk role where I can apply hands-on hardware, Linux, Windows, networking, and customer-service experience from day one, grow within the company, and progress toward NOC and SOC operations.

I've delivered custom software, multimedia, and client projects as a freelance IT professional in Brazil and Portugal for over two decades. At Arena, I taught hardware courses and provided end-to-end support, from computer assembly and repair to system installation and LAN administration.

I'm now transitioning into technical support and helpdesk, supported by hands-on Windows, Linux, networking, Python, SQL, and cybersecurity training. I'm pursuing degrees in Computer Engineering, Computer Networks, and Cybersecurity & Defense Management, with a clear path toward network and security operations.
