        </h1>
        <p>
          Hello 👋, my name is <span class="noteText">Anjan Roy</span> and I am a Computer Programmer, living in
          <span class="noteText">UAE</span>, originally from <span class="noteText">India</span>.
          In 2018, after completing my under-graduate in Computer Science, I started practising software development
          while continuing post-graduate study in Computer Science. In 2020, after earning M.Sc. in Computer Science, I moved
          to industry full-time.
          <br>
          <br>
          I'm working as an Engineer in the Explorations Team of the <a  class="simpleLink" href="https://availproject.org" target="_blank">Avail Project</a>.
          Along with that I'm also pursuing PhD in Applied Cryptography @ <a class="simpleLink" href="https://www.ru.nl/dis" target="_blank">Digital Security (DiS) Group</a> of <a class="simpleLink" href="https://www.ru.nl" target="_blank">Radboud University</a>,
          under the guidance of <a class="simpleLink" href="https://cs.ru.nl/~joan" target="_blank">Prof. Joan Daemen</a>.
          <br>
          <br>
          I'm a big fan of open-source. Naturally, I write and maintain some open-source projects. See my <a class="simpleLink" href="https://github.com/itzmeanjan" target="_blank">Github profile</a>.

          education

        <p>
          I did my <span class="noteText">B.Sc. & M.Sc. in Computer Science</span> from Dept. of Computer & System
          Sciences, <a class="simpleLink" href="https://visvabharati.ac.in/index.html" target="_blank">Visva-Bharati, Santiniketan, India</a>.
          I've started pursuing a <span class="noteText">PhD in Applied Cryptography</span> from the <a class="simpleLink" href="https://www.ru.nl" target="_blank">Radboud University, Nijmegen, The Netherlands</a>.
          I'm being supervised by <a class="simpleLink" href="https://cs.ru.nl/~joan" target="_blank">Prof. Joan Daemen</a> and co-supervised by <a class="simpleLink" href="https://gva.noekeon.org" target="_blank">Dr. Gilles Van Assche</a>.
          During my PhD, I'll be studying design and implementation of both symmetric-key and post-quantum cryptography. I plan to focus on modernizing the state of the symmetric key cryptography.
          <br>
          <br>

          If I've free time I go for bicycling. Other than that, I love to watch movies, tv series.
          Sometimes I read books or work on some of my side projects on Github.
