ADITYA KUMAR SINGH · b. 1988, VARANASI
Hello, I’m Aditya.
I build software,
and write about why.
I’m an engineer who’s spent over a decade building software in the healthcare domain — currently leading engineering at Firefly Health. I write here because I think out loud better than I think alone, and because the internet was kinder to me when other people did the same.
These days, I’m focused on one thing on the side: a personal initiative called Mridula — named after my mother — to bring small, honest prototypes of tech and capital to rural livelihoods in India. It is a current chapter, not the whole book.
§ ABOUT

§ CURRENT FOCUS2026 —
Mridula — small, honest prototypes for rural India.
Each prototype ships to a real URL with a README, an honest open question, and a post about what I learned. The point is the learning — and the small, honest impact a real, shipped thing can have along the way.

Fifteen Years In: A Letter to Myself at Ten
I wrote a career-advice piece five years ago, at the ten-year mark. Here it is again, annotated by the person I am now — and with one section the original couldn't have anticipated.
