-<p>I&rsquo;m a passionate and highly motivated software engineer with a deep-rooted love for technology that dates back to my first computer, an Amstrad 8256. From those early days of programming as a hobby, I&rsquo;ve turned my passion into a successful career, specializing in mobile development with a focus on Android.</p>
 
-<!-- raw HTML omitted -->
 
-<h2 id="professional-journey">Professional Journey</h2>
 
-<p>Currently, I&rsquo;m leading the mobile team at Game Golf, where I oversee all aspects of our mobile app development. My experience spans various domains, including:</p>
 
-<ul>
 
-<li>Android app development and maintenance</li>
 
-<li>iOS development</li>
 
-<li>Backend technologies like Spring Framework and RESTful APIs</li>
 
-<li>Working in fast-paced, agile environments</li>
 
-</ul>
 
-<p>Throughout my career, I&rsquo;ve contributed to award-winning apps and worked with startups and established companies alike. I take pride in writing clean, efficient code and designing scalable solutions that adhere to best practices in object-oriented programming.</p>
 
-<h2 id="technical-expertise">Technical Expertise</h2>
 
-<p>My skill set includes:</p>
 
-<ul>
 
-<li>Proficiency in Java, Kotlin, and Android SDK</li>
 
-<li>Experience with iOS development</li>
 
-<li>Familiarity with various libraries and frameworks (RxJava, Dagger2, Room, LiveData, etc.)</li>
 
-<li>Version control with Git</li>
 
-<li>Database technologies (SQLite, MongoDB)</li>
 
-<li>Some web development (HTML, CSS, JavaScript)</li>
 
-</ul>
 
-<p>I&rsquo;m always eager to learn and stay up-to-date with the latest trends in technology, particularly in the mobile development world.</p>
 
-<h2 id="beyond-coding">Beyond Coding</h2>
 
-<p>Outside of my professional work, I&rsquo;m an active member of the tech community. I co-founded 091 Labs, a local hackerspace, where I&rsquo;ve conducted workshops on Android development. I&rsquo;m also passionate about open-source projects and have contributed to various initiatives on GitHub and Launchpad.</p>
 
-<p>As a multilingual professional fluent in English, Catalan, and Spanish, I bring a global perspective to my work and enjoy collaborating with diverse teams.</p>
 
-<p>Whether it&rsquo;s developing innovative mobile applications, contributing to open-source projects, or sharing knowledge with aspiring developers, I&rsquo;m always excited to take on new challenges in the ever-evolving world of technology.</p>

-      <title>Configuring SSH Keys for Individual Git Commands</title>
 
-      <link>https://codeskraps.com/posts/2024/git_ssh_command/</link>

-      <guid>https://codeskraps.com/posts/2024/git_ssh_command/</guid>
 
-      <description>&lt;p&gt;When working with Git repositories, you often need to authenticate using SSH keys. While you can configure SSH settings globally, there are times when you need to use a specific SSH key for just one command. This is particularly useful when cloning a new repository or adding a submodule, where there isn&amp;rsquo;t yet a local &lt;code&gt;.git/config&lt;/code&gt; file to modify.&lt;/p&gt;</description>

-
 
-KaTeX is a fast, easy-to-use JavaScript library for TeX math rendering on the web.
 
-
 
- * **Fast:** KaTeX renders its math synchronously and doesn't need to reflow the page. See how it compares to a competitor in [this speed test](https://www.intmath.com/cg5/katex-mathjax-comparison.php).
 
- * **Print quality:** KaTeX's layout is based on Donald Knuth's TeX, the gold standard for math typesetting.
 
- * **Self contained:** KaTeX has no dependencies and can easily be bundled with your website resources.
 
- * **Server side rendering:** KaTeX produces the same output regardless of browser or environment, so you can pre-render expressions using Node.js and send them as plain HTML.
 
-
 
-KaTeX is compatible with all major browsers, including Chrome, Safari, Firefox, Opera, Edge, and IE 11.
 
-
 
-KaTeX supports much (but not all) of LaTeX and many LaTeX packages. See the [list of supported functions](https://katex.org/docs/supported.html).
 
-
 
-Try out KaTeX [on the demo page](https://katex.org/#demo)!
 
-
 
-## Getting started
 
-
 
-### Starter template
 
-
 
-```html
 
-<!DOCTYPE html>
 
-<!-- KaTeX requires the use of the HTML5 doctype. Without it, KaTeX may not render properly -->
 
-<html>
 
-  <head>
 
-    <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/katex@0.16.2/dist/katex.min.css" integrity="sha384-bYdxxUwYipFNohQlHt0bjN/LCpueqWz13HufFEV1SUatKs1cm4L6fFgCi1jT643X" crossorigin="anonymous">
 
-
 
-    <!-- The loading of KaTeX is deferred to speed up page rendering -->
 
-    <script defer src="https://cdn.jsdelivr.net/npm/katex@0.16.2/dist/katex.min.js" integrity="sha384-Qsn9KnoKISj6dI8g7p1HBlNpVx0I8p1SvlwOldgi3IorMle61nQy4zEahWYtljaz" crossorigin="anonymous"></script>
 
-
 
-    <!-- To automatically render math in text elements, include the auto-render extension: -->
 
-    <script defer src="https://cdn.jsdelivr.net/npm/katex@0.16.2/dist/contrib/auto-render.min.js" integrity="sha384-+VBxd3r6XgURycqtZ117nYw44OOcIax56Z4dCRWbxyPt0Koah1uHoK0o4+/RRE05" crossorigin="anonymous"
 
-        onload="renderMathInElement(document.body);"></script>
 
-  </head>
 
-  ...
 
-</html>
 
-```
 
-
 
-You can also [download KaTeX](https://github.com/KaTeX/KaTeX/releases) and host it yourself.
 
-
 
-For details on how to configure auto-render extension, refer to [the documentation](https://katex.org/docs/autorender.html).
 
-
 
-### API
 
-
 
-Call `katex.render` to render a TeX expression directly into a DOM element.
 
-For example:
 
-
 
-```js
 
-katex.render("c = \\pm\\sqrt{a^2 + b^2}", element, {
 
-    throwOnError: false
 
-});
 
-```
 
-
 
-Call `katex.renderToString` to generate an HTML string of the rendered math,
 
-e.g., for server-side rendering.  For example:
 
-
 
-```js
 
-var html = katex.renderToString("c = \\pm\\sqrt{a^2 + b^2}", {
 
-    throwOnError: false
 
-});
 
-// '<span class="katex">...</span>'
 
-```
 
-
 
-Make sure to include the CSS and font files in both cases.
 
-If you are doing all rendering on the server, there is no need to include the
 
-JavaScript on the client.
 
-
 
-The examples above use the `throwOnError: false` option, which renders invalid
 
-inputs as the TeX source code in red (by default), with the error message as
 
-hover text.  For other available options, see the
 
-[API documentation](https://katex.org/docs/api.html),
 
-[options documentation](https://katex.org/docs/options.html), and
 
-[handling errors documentation](https://katex.org/docs/error.html).

- *  This file implements a KaTeX version of mhchem version 3.3.0.
 
- *  It is adapted from MathJax/extensions/TeX/mhchem.js
 
- *  It differs from the MathJax version as follows:
 
- *    1. The interface is changed so that it can be called from KaTeX, not MathJax.
 
- *    2. \rlap and \llap are replaced with \mathrlap and \mathllap.
 
- *    3. Four lines of code are edited in order to use \raisebox instead of \raise.
 
- *    4. The reaction arrow code is simplified. All reaction arrows are rendered
 
- *       using KaTeX extensible arrows instead of building non-extensible arrows.
 
- *    5. \tripledash vertical alignment is slightly adjusted.
 
- *
 
- *    This code, as other KaTeX code, is released under the MIT license.
 
- * 
- * /*************************************************************

- *
 
- *  KaTeX mhchem.js
 
- *
 
- *  This file implements a KaTeX version of mhchem version 3.3.0.
 
- *  It is adapted from MathJax/extensions/TeX/mhchem.js
 
- *  It differs from the MathJax version as follows:
 
- *    1. The interface is changed so that it can be called from KaTeX, not MathJax.
 
- *    2. \rlap and \llap are replaced with \mathrlap and \mathllap.
 
- *    3. Four lines of code are edited in order to use \raisebox instead of \raise.
 
- *    4. The reaction arrow code is simplified. All reaction arrows are rendered
 
- *       using KaTeX extensible arrows instead of building non-extensible arrows.
 
- *    5. \tripledash vertical alignment is slightly adjusted.
 
- *
 
- *    This code, as other KaTeX code, is released under the MIT license.
 
- * 
- * /*************************************************************
 
- *
 
- *  MathJax/extensions/TeX/mhchem.js
 
- *
 
- *  Implements the \ce command for handling chemical formulas
 
- *  from the mhchem LaTeX package.
