Killing the Monday Morning Rent Roll Scramble

About

I'm a former Sr. Business Analyst at a $200M DTC cookware brand, where I built the demand forecasting engine used across 450+ SKUs and four countries.

Before that, I was the person everyone dumped their broken spreadsheets on, so I got really good at fixing them. These days I do that for a living: Python, Google Apps Script, n8n, Airtable, and the Shopify API. Whatever it takes to get your business off duct-taped formulas and onto something that actually works while you sleep. Based in Austin, TX, working with clients everywhere.
