<h2>arf20</h2>
<p>
Hello there, I'm arf20, a 18 y/o bi femboy student from Spain
obsessed with technology, hardware and software.
</p>
<p>
My passions and hobbies are: Linux, systems programming,
servers (hardware and administration), networking,
electronics (analog, digital and radiofrequency),
and retrocomputing. I mostly find expensive professional
technology super fascinating.
</p>
<p>
I really align myself with Free (as in Freedom!) and Open Source
and Right to Repair movements, trying to use free software wherever
I can. My favorite distro is Debian and I run it everywhere but
my phone.
</p>
<p>
I'm currently studying Computer Science at Universidad de Murcia since 2023,
first year. I think this is my place tbh, nice people, great projects.
</p>
<h2>Technologies</h2>
<p>My <a href="/cv.html">CV</a>.</p>
<p>
Pretty fluent in C/C++, MIPS, Z80 and x86 assembly,
some Java too. I usually use CMake or Make as build systems.
In terms of web, I know PHP, SQL, HTML, CSS and a
bit of JS. Good use of Git version control.
</p>
<p>
I'm knoledgeable in system administration of Web hosts using the
linux/nginx/mariadb stack, email with postfix/dovecot and a number of others.
I build grafana dashboards for them.
I am familiar with Proxmox virtualization as well as linux containers,
systemd and general linux administration but also *BSD and Solaris.
</p>
<p>
About network administration, I'm ok at OPNSense/pfSense firewalling,
segregation, VLANs, tunnels, VPNs, etc.
</p>
<p>
Hardware-wise, I've come knees deep with DELL R-series server hardware
and its management, and of course a fair bit of PC building.
In terms of networking, Mikrotik, Cisco and DELL PowerConnect I experienced.
</p>
<h2>Misc</h2>
<p>
I am a native Spanish speaker, and I've been told I'm pretty
good at English too, although oficially I currently only hold a B2 by EOI.
</p>
<p>
Random things I have are, HE IPv6 Certification, CEPT Radioamateur License (EA5JGX),
ARPA membership on SDF, and interestingly Galileo Mastermind prize at HackUPC 2024.
</p>
<p>
As an annex, I know some digital and analog electronics, MCUs,
high voltage electric handling, PCB design,
radioelectronics, antenna building and SDRs. <br>
But also, retrocomputing, from 1980s PC to 1990s UNIX workstations,
and their old OSs (DOS, Solaris, IRIX...) and software.<br>
And lastly, multimedia production, recording, editing, streaming,
and music theory and playing.
