About
Fifteen years in product, now building solo.
I'm trained as an engineer (BITS Pilani) with an MBA (SP Jain), but the last fifteen years have been in product, mostly in education. The Indian years were at CueMath, Byju's, and a few others. There were stops at Noon Learning in the Middle East, and at Babbel and Delivery Hero in Berlin. Across all these places, my job came down to the same thing: champion the user's problem, then experiment and iterate until the digital product actually solved it.
I tried co-founding my own thing once before. In 2013, during my MBA, I started AcadMentor: an adaptive math learning product for middle school students. It pivoted a few times and shut down. Wrong timing, not enough skills, not enough capital. The wanting-to-build-my-own-thing has been there since, and what I'm doing now is the second attempt with better tools and twelve more years behind it.
More recently, I started learning to build software with AI tools. The shift from working inside a product team to building alone is what most of my current writing here is about. The Now page covers what I'm specifically working on; this page is for the longer arc.
Mentoring and Teaching
I also mentor product managers and designers. The formal version is a course I created on product management and free 1-on-1 slots I run on ADP List. The informal version is a longer trail of people I've worked with and people who find their way to me through this writing.
What this site is
This is not a portfolio or a résumé. It is a public workspace.
The Problem Notes are short explorations of questions I'm actively thinking about, each tagged with how settled the thinking is. The Case Studies document how some of those questions played out in real situations, with the trade-offs and imperfect outcomes named. The Now page captures what currently has my attention.
I don't publish frequently, and I don't aim to be exhaustive. I write when the thinking is articulate enough to share, even if it isn't finished.
