Karthick Aravindan
I'm interested in how things work beneath the surface—from AI and software to businesses, financial markets, and the decisions that shape them. I build, experiment, study the results, and write down what I learn.
A public notebook of work in progress. Not a claim to have everything figured out.
I build software and AI products, explore financial systems, study how businesses work, and document what I learn. The record is allowed to change.
