About Me
Sehej Singh
Master's in Data Science
University of San Francisco
Background & Education
Born and raised in Sacramento, California, I discovered my passion for data science and machine learning during my undergraduate studies at Loyola Marymount University. I recently graduated with my Master's in Data Science from USF, where I dove deep into advanced ML techniques, statistical modeling, and AI applications.
Professional Journey
My experience spans from developing RAG-based AI chatbots at ArsLab.AI to building mortgage analytics models at Buyer Folio, and creating cryptocurrency market prediction systems at 7VFI.AI. I specialize in turning complex data into actionable insights and building scalable ML solutions.
Beyond Data Science
When I'm not coding or analyzing data, you'll find me on the basketball court, at the gym, playing chess, or dancing Bhangra. I'm also a food enthusiast always exploring new cuisines and flavors!
