Hello World

Deciding to write anyway.

I've started this blog three times in my head before actually starting it. Each time, I talked myself out of it. Too busy. Not ready. What would I even say? Let's wait until I have something worth saying.

But I think that's a trap. You wait until your ideas are polished enough to share, and in the meantime they're just there, circulating, nagging in your mind. Taking up space without going anywhere.

So this is me deciding to write anyway. Not to build an audience. Not to position myself. Just to think better.

I don't know what this blog will become. I have a few threads I'm pulling on about AI, about building, about what it means to come from somewhere (nowhere?) and try to make something. Those will show up here eventually.

But for now, I'm here. I'm writing. And I'm doing it mostly for myself.

If something resonates with you, great. If not, that's fine too.

More soon.

AboutMe

Hi, I'm Raisul Chowdhury, a data scientist and product builder in San Francisco.

I grew up in Dhaka, moved to Toronto in my twenties, did an MBA at Kellogg, and have been in California with my wife and son ever since. Before Google, I helped grow StackAdapt from 70 to 1,000 people. And way before that, product and growth across digital platforms in emerging markets.

My titles changed over time, but the work I do stayed the same: understand the user, find the gap, ship it, learn, ship again.

These days I build AI products at Google and write about where the machines end and we begin. The bet underneath: AI that makes the person using it sharper, not smaller. I don't know if it's right yet. I'm building toward it.

When I'm not working, I'm usually at the park with my son, making waffles, or sitting with music and chai thinking about what comes next.
