  <p>In a small world where everyone tries to be different, there's this guy called Simon who is just as talented as other guys but can adapt to any environment he finds himself in.</p>
  <p>It's hard to say what Simon loves because he loves doing anything as long as it is related to computers & the internet. You can call it "HIS WORLD"!</p>
  <p>Simon grew up in Togo and moved to Nigeria in 2011. Back in Togo, Simon loves to fix broken toy cars and have always wondered how they were capable of moving using a remote control. I guess his curiosities started to make sense the day his Dad got a laptop for him. He wouldn't stop EXPLORING!</p>
  <p>Simon dreams of using technologies to tackle the problems we face daily, using technologies to better human lives and he doesn't learn anything without having something to show for it.</p>
  <p>This is a brief introduction to a GREAT man called Simon.</p>
