I write mostly about what I do at work and what I've learned along the way: Django, Rails, Flutter, Postgres, and the servers all of it runs on. Older pieces live on Medium.

There’s also startups, and philosophy, mostly centered around my learnings from Vedanta, the Brahma Sutras, the Yoga Sutras and the Upanishads. I write poems too, and try to make them funny so that they can resemble Sukumar Ray, one of my favorite childhood Bengali poets.

Hope you enjoy at least some of them.
