probably-pancakes

R

A machine learning app that answers the only question that matters: does this recipe make pancakes? Trained a Random Forest classifier on 3,200 recipes scraped from the web, then wrapped it in a polished Shiny app. Born from a household mystery — a scrap of paper labeled ‘probably pancakes.’

  • Invested in custom CSS and visual polish — the joke lands better when the app looks like a real product
