Leah Kat Insights, Data Analytics for Finance, Hospitality, Sports & Ecommerce

Where data meets creative strategy.

I like taking a messy dataset and turning it into a plan someone can act on. I'm currently working on my MBA with a concentration in Data Analytics and a specialization in Hotel & Casino Management.

I built my career in ecommerce, from digital strategy to inventory and P&Ls. My focus now is data analytics, data infrastructure, and cloud engineering: the pipelines bringing the numbers in, aimed at sport and hospitality. I'm a sports fanatic at heart, if it's not revenue analytics, it's sports stats.

Outside of work you'll find me near the ocean with my red merle Australian Shepherd, River, my kids, anywhere that involves trails, beaches, or both.

A blurb on AI (and how I use it)

Did I use AI to help build this website? Yes.

Could I have built it without it? Also yes.

(It just would've taken me longer. Probably would've been better, to be honest.)

I come from the days of building websites from a blank page, even ecommerce sites (anyone remember OSCommerce built off SQL database?) HTML, CSS, JavaScript, and a lot of nights spent debugging. Before any of that, I started at art school. I truly value human creativity, intuition, knowledge, collaboration, and oversight. I refuse to use AI to replace any of this.

I use AI for efficiency, not for creativity or content. The purpose is intentional and minimal. I find it good at some of the mundane, tedious work: organizing, cleanup, planning, first-pass debugging, reformatting the same dataset for the tenth time. It can make the coding process more efficient than continuous copying/pasting (IYKYK). Handing that off leaves more room for the parts that actually matter, strategy and creative thinking.

The ideas, writing, and analysis on this site are mine. Human first, always.

and on that note, I vow to never respond to your emails with an automated AI response.
