Writing
Notes from under the hood
The engineering that never makes it onto a slide: one honest write-up per project, the decision that was actually hard, and why it mattered.
- The code is the thing every analytics tool is blind to→July 2026
PostHog can tell you a button was clicked 1,240 times. It cannot tell you it was the wrong button, because it never sees the code.
- It doesn't grade your answer. It reads how you decide.→July 2026
One scenario, three calls, and in ten seconds you see your score, your rank against every operator who played, and a portrait of how you actually think.
- Most AI agents are a for-loop in a trench coat→July 2026
The first version of my marketing agents did not reason. They returned constants and called them scores. Fixing that was the whole product.
- How not to dial a thousand people by accident→May 2026
Serverless makes it trivially easy to place a thousand phone calls at once. Most of the engineering was making sure it can't.
- The statement your registrar emails you, that nobody can read→April 2026
Every mutual-fund investor in India already gets a complete portfolio statement by email. It is a password-locked PDF in four incompatible formats. That is the whole onboarding wedge.
- Three companies run their whole operation on it, and none of them are mine→June 2026
Getting one external company to run its entire operation on your infrastructure is hard. Three of them, none alike, is the real proof it holds.
- Gate, don't average→May 2026
The carbon market's whole credibility problem is projects that average their way past a fatal flaw. So the integrity score has a floor you cannot average over.
- The hard part was never the model→June 2026
Everyone is racing to build on top of the data. Almost nobody wants to go get it.
- Heart disease doesn't present the same in women. Neither should the course.→February 2026
Arogya Nari teaches women's health through interactive 3D anatomy that runs in a browser tab, for someone who will never install an app, often in Hindi, on a modest phone.
