I’m an author, researcher and programmer from Colombo, Sri Lanka.

You can find my work on Goodreads, Icaruswept, Readme, Medium. and quite a few other places besides – including the Sunday Times, the Island, the Sunday Leader, the Nation and Colombo Telegraph.


Numbercaste is here!

(in both Kindle and paperback)

Here’s what my fellow authors have said about it:

“Fantastic, detailed world-building and characters with heart bring this story to life. Wijeratne has held up a chillingly realistic mirror on our interconnected society.” – Paul Anlee, author of The Reality Thief

I cannot even begin to tell you how awesome this is. I can happily say it is the best book I’ve read this year.” – Navin Weeraratne, author of The Hundred Gram Mission

Prophetic, Orwellian, and not wholly inconceivable . . . the depth of Numbercaste lies in how readily we are able to envision this not-so-distant future.” – Amanda Jay, author of The Other One


If you’d like to read some of my work for free, try The Slow Sad Suicide of Rohan Wijeratne (no relation). It’s about a man who signs up to be shot into a Kerr singularity – that’s a black hole whose rotation flattens it out into a ring.

It’s got some rave reviews on Goodreads, hit the #1 spots on Amazon’s scifi and lit-fic bestseller lists, and you can now download it from Amazon.
