What I do
Build. Write. Teach.
Everything here comes from the same place: two decades of building systems in production, and the conviction that the parts college skips are the parts that matter most.

Books & articles
From Bits to Systems is the first book in the Foundation Series. The articles preview its ideas: UPI's architecture, the AI hype filter, IT services versus product companies.

Lectures & mentoring
Guest lectures at engineering colleges, curriculum consulting for departments, and hands-on mentoring of junior engineers — focused on long-term craft, not just interview prep.
Work with AshwinWhy the book exists
Most programming books fail Indian engineering students. Here's the gap.
What college teaches
How to pass test cases.
University courses are built around exams — algorithm problems, syntax rules, and assignments that test your memory, not your judgement. You learn to write code that passes tests, not code that holds up in a real job.
What the industry pays for
Solving actual human problems.
Software engineering is about solving human problems, not just writing code. The engineers who do well understand why systems are built the way they are. This book bridges that gap — specifically for India.
