Some awesome people I've had the pleasure to work alongside.
Dr. Saed Sayad
Data Scientist, Real Time Analytics for Big Data

Gurpreet has a Creative mind and a Powerful analytical brain. He joined my team as a Junior Data Scientist and in the first few months his productivity surpassed my expectations of even a senior data scientist. Besides his unique analytical skills he is an expert programmer with an Extensive knowledge of Big Data Technologies and Platforms. The sky is the limit for this young nice man and I see a very bright future for him.

Dawid Zambrzycki
Senior Yield Manager at AdTheorent

Gurpreet will be there for you. Every time there was a need for a last minute model, he would put in the work and effort in until the job was done. He would then follow up the next day with improvement of his own. As a deskmate, he is a pleasure to have around and let's not even get started about his phenomenal computer skills.

Lee Carlin
Senior Data Scientist at AdTheorent

Gurpreet is the team member every engineer and a Data Scientist are lucky to have in their team. A hardworking, extremely focused and methodical individual, Gurpreet has been successfully leading some of the team's most demanding projects with an admirable calm and patience. As a colleague I could always count on him to provide strong and creative results in a timely manner. Gurpreet has been our go-to team member for effective state-of-the-art technical skills and support for almost three years, and his positive influence on our team will surely be missed.

Dan Jenkins
Director of Data Science at AdTheorent

I worked with Gurpreet closely on several projects during his time at AdTheorent. Gurpreet has strong programming and data analysis skills and delivers consistent results. He understands the connection between his work and the underlying business goals, and I trust him to take leadership on complex projects and make quality decisions. I've relied on his expertise to solve many of the difficult problems faced by our team, and will miss his contributions.

Chris Way
Senior Yield Manager at AdTheorent

I had the pleasure of working closely with Gurpreet during my time at AdTheorent. Gurpreet is a methodical, creative data scientist who is very skilled in a wide range of data analytic and modeling approaches. He integrates well with operational and business initiatives, and is always eager to apply his analytic prowess to solve client-related challenges and requests. He is adaptive, friendly and optimistic even in the face of particularly thorny business and data problems, and integrates very well with tech and non-tech folks alike.
