This is a summary of some of my projects.

CoPlanner

One of my favorit projects was to build CoPlanner, a language model powered app that streamlines ad operations. It processed more than 20k campaigns representing a combined spend USD $200M. What took many minutes or even hours can be done within seconds.

It parses campaign details like dates, targeting, budget, etc (around 30 fields overall). Once validated (using both Pydantic and humans), the app then creates the campaign automatically.

RAG Brand Prediction

Predicting the brand of an ad is incredibly difficult given that there are mullions of options.
