About

Two interests. One person writing about both.

Finance

Systems, tools, data

Credit card math. FIRE strategy. Trading decisions. The interesting stuff is rarely what the influencers cover.

AI

Context, agents, what works

Building practical AI systems as someone whose background is not software engineering. Less demo, more dependable.

Who I am

I am Aayush Goenka. Fifteen years working with data in Silicon Valley, most of that time helping product and business teams make decisions with numbers. I currently lead data analytics at Poshmark.

What I write about

Both topics on this site are the same thing in different costumes: organized thinking applied to complex systems. Better systems produce better outcomes. The systems are usually simpler than they look.

On the finance side, that means looking past the surface narrative (“Amex Platinum is too expensive”) to the math that actually plays out ($2,300 net positive if you use the credits). On the AI side, it means looking past the demo (“AI can write code”) to the architecture that makes it dependable across months of work.

Why this exists

The writing forces me to think clearly. If you find any of it useful, that is a bonus. If you disagree with something, I want to hear about it.

The easiest place to reach me is LinkedIn.
