about
</h1>
<p>
Hello 👋, my name is <span class="noteText">Anjan Roy</span> and I am a Software Engineer, 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 a Senior Cryptography Engineer @ <a class="simpleLink" href="https://tii.ae/cryptography" target="_blank">Cryptography Research Center, Technology Innovation Institute, Abu Dhabi.</a>.
<br>
<br>
Currently I practise <span class="noteText">applied cryptography</span>. Being an avid open source contributor, I maintain some
open source projects. See <a class="simpleLink" href="https://github.com/itzmeanjan" target="_blank">this</a>.
