Satisfied Customers


We worked with Katharine on an early data-pipeline prototype using both existing and custom natural language processing models to parse French and English texts. Katharine was of tremendous help getting the thing up and running, having a deep understanding of the state of the art and how to improve it. We went from 0 to running prototype in a few months, and we would have never been able to achieve it without her skills and knowledge.

Romain Dorgueil, Technology Manager at L'Atelier (BNP Paribas)

Katharine is an inspiring and energetic engineer. Quick to understand business needs, she can act as product owner and business sparring partner to make sure you're aligned and focused. Her wealth of python experience and coaching style made her a popular member of the Marketing Engineering team, and allowed the small team to deliver outstanding results on a mission critical project.

Andy Wilson, Director of Marketing, GetYourGuide

We worked with Katharine on a data-scraping project. Katharine was quick to understand and apply her own ideas to the business need and even quicker to deliver very tangible and high quality results. We found working with Katharine to be very pleasant and engaging - and would not hesitate to use her services again!
