Hi! I'm Ankush!

I’m a 👨🏻‍💻 programmer who loves technology. From 🕸 web-development, deep-learning, devops to everything that Elon Musk does.

In addition to coding, I also look at how good products & businesses work from many contradictory points of view.

Recently, I have started thinking a lot about philosophical questions so you’ll find a lot of related posts.

This blog is the way I process my 🎲 thoughts and solve problems. If you read any, try scrutinizing them and see if they hold.

I treat this blog as a wiki, so old post of frequently reworded or deleted.
