<h2><a href="#top">^</a> DESCRIPTION</h2>
<p>
I'm an open-source programmer
focused on the quality of the code.
As with Debian,
I release code "when it's ready".
</p>
<p>
I've programmed many small projects for myself using C
for more than a decade.
You can find most of those projects in my
<span class="name">cgit</span>
<a href="https://www.alejandro-colomar.es/src/">server</a>,
released with an open-source license.
</p>
<p>
I also contribute to (and in some cases maintain) widely-known projects,
including, but not limited to the following list:
<ul>
<li class="bullet"><h5><span class="name"><a href="https://codidact.org/">Codidact</a></span></h5></li>
<li class="bullet"><h5><span class="name"><a href="https://conan.io/">Conan</a></span></h5></li>

</ul>
</p>
<p>
I've contributed to those (and more) projects with
patches, bug reports, testing, reviews, suggestions, Q&A, etc.
When contributing to those projects,
I enjoy participating in discussions that attempt to find the
best possible solution to a given issue.

<div id="notes">
<h2><a href="#top">^</a> NOTES</h2>
<p>
From the many free and open-source projects I've contributed to,
some of them are especially relevant:
</p>
<ul>
<li>
<h4 class="inl"><a href="https://www.kernel.org/doc/man-pages/">
<span class="name">Linux man-pages</span></a></h4>
<p>
I started contributing to the Linux man-pages project to
document some kernel/libc features
that I needed for some personal projects
but found to be undocumented.
A few months later,
I joined the project as a comaintainer,
after receiving a proposal due to
the quality and quantity of my contributions.
</p>
<p>
The
<a href="https://linux-man-pages.blogspot.com/">project blog</a>
covers the most relevant changes I introduced in the project.
</li>
</p>
<p>
While contributing to the project,
I regularly test the
<span class="name">Linux</span>
kernel and
<span class="name">C</span>
library APIs,
develop example programs using the APIs,
review and write technical documentation,
and also find and report bugs to related projects.
</p>
</li>
<li>
<h4 class="inl"><a href="https://github.com/shadow-maint/shadow">
<span class="name">shadow-utils</span></a></h4>
<p>
I've updated the
<span class="name">shadow-utils</span>
source code from
pre-<span class="name">ANSI C</span>
to
<span class="name">C11</span>
and
<span class="name">POSIX.1-2008</span>.
I'm also overhauling the code for manipulating strings,
and allocating memory,
and in general making the source code more robust.
</p>
<p>
These changes have allowed finding and fixing many bugs,
and have also resulted in a smaller
and much more readable code base.
</p>
<p>
Since version 4.14,
I maintain the stable branches of the project at
<a href="https://www.alejandro-colomar.es/src/alx/shadow/stable/shadow.git/"><https://www.alejandro-colomar.es/src/alx/shadow/stable/shadow.git/></a>.
</p>
<li>
<h4 class="inl"><a href="https://unit.nginx.org/">
<span class="name">NGINX Unit</span></a></h4>
</p>
I participated in the development of
<span class="name">NGINX Unit</span>.
</p>
<p>
I mostly did
<span class="name">C</span>
programming,
adding new features and fixing bugs,
but also regularly helped in all other aspects of the project.
</p>
<p>
One of the most notable features,
which for schedule reasons hasn't yet been released,
has been to allow chaining actions in the server,
which was inspired by shell pipes.
It would allow chaining arbitrary applications
to process a request,
simplifying what each of the applications needs to do.
</p>
<p>
Another notable feature was
adding a compression filter
(initially supporting only GZIP, but easily extensible).
The performance is significantly better than that
of NGINX's gzip filter,
and the implementation is simpler.

<h2><a href="#top">^</a> EDUCATION</h2>
<p>
I've studied various degrees,
receiving very high marks and special mentions,
but I haven't finished any due to various reasons
(including lack of interest in official certifications).
</p>
<p>
I've also studied many dozens of online courses from
<span class="name"><a href="https://www.edx.org/">EdX</a></span>
and other sites,
learning many completely different subjects,
from Calculus, to Solid State Chemistry or Hypersonics.
</p>
<p>
Apart from that, which I've done only for my own curiosity,
a few courses are very relevant to my job:
</p>
<ul>
<li class="br">
<h5 class="inl"><span class="name"><a href="https://man7.org/training/">man7.org Training and Consulting</a></span>:</h5>
