I'm a product engineer. By day I work on AI, infrastructure and backend at Cityflo, helping solve the daily commute across Indian cities. In my own time I ship open-source tools and write GTM Engine, a free weekly newsletter on how products actually get built, sold and found when AI changes how companies buy.
Tech, Finance and Capitalism. I work at the intersection of all three to help startups and companies outgrow their revenue.
