Before I went to university, music was a huge part of my life. I'm hoping that one day I will have the time/incentive to make music again.

Mind Gate

In high school (and the first two years of university), I played guitar in a band called "Mind Gate", and pretty well too. In its lifetime, Mind Gate gave a bunch of concerts, interviews, and most importantly, released three demo albums.

Our final demo (called "Spiral") was officially released by an Italian record label company, Lucretia Records, and is still available on Amazon. There's also a lot of Mind Gate music available on our Myspace page - I think two whole albums - and there's a fan video on Youtube (!). Enjoy!


Back in high school I used to read books en masse. This has translated into a couple of (sci-fi) novels and short stories that I have published throughout the years. I have also published and contributed a couple of blog posts and articles, some of which are listed below:

  • Fixing Covid-19 Case Number and Death Toll Underreporting - available via Medium, and LinkedIn
