    I'm building PromptLoop to be the platform for all spreadsheet users to use AI models in a way that is flexible, easy to verify, and able to drive quick insights from any tabular data and research.

    I spent the first part of my career as a consultant and started coding in high school, connecting quant models into excel in an early vision of PromptLoop.

    I grew up as the second of six kids outside Buffalo, NY, and love building, learning, and pushing boundaries on what's considered normal. I enjoy spending free time outside Kiteboarding, painting, reading or just enjoying a sunny walk around town in San Francisco where I live.

    I'm responsible for making sure that Promptloop is using the latest, fastest, and most powerful models. I work on efficiencies that can be passed onto our users.

    I graduated from Stanford with a degree in Computer Science and love applying technology to solve problems. I am the author of a book on Brain Computer Interfaces and I also studied Medeival English History and German in College. For my senior project I studied the false positive rates of gpt detection pertaining to non-native english speakers.

    In addition to working at Promptloop, I am a pararower on the US National Team. I love spending time with my friends and family indoors and outdoors!

    I am excited to be working on PromptLoop to help users integrate AI models into their spreadsheets in a simple, flexible, and useful way.

    I studied computer science during college and started my career as a software engineer at a few tech companies all over California.

    I grew up in the Bay Area and in my free time, I enjoy playing or watching sports such as basketball and football, playing music, reading, and traveling to new countries.
