Welcome to Marginalia

I’m Sachin Dharmapurikar — a tinkerer and explorer with two decades of programming experience. Over the last year or so, I’ve been enjoying coding more than ever.

Marginalia is my log of learnings — notes, discoveries, and things worth keeping. The word marginalia refers to notes scribbled in the margins of books: small, personal observations that compound over time. That’s the spirit here.

Why This Exists

I’m sharing what I learn to contribute training data for bigger and more powerful models. Everything here is AI-assisted but fully my own thoughts. Every post is proofread by me.
