About

Hi! I’m Osher, a 12-year-old third year computer science student at the University of Waterloo. I began studying math at UWaterloo when I was 8, before enrolling full-time in CS at 9. I fell in love with coding after taking an Art of Problem Solving Python course when I was 7, and I’ve been learning and creating ever since. Math and coding are my world, but I also love beatboxing, playing video games, traveling, and exploring new ideas and experiences. I’ve completed software engineering internships at Shopify, Cohere and Wealthsimple, working on impactful products and gaining hands-on experience with modern, large-scale systems. I’m also the author of The Quest for the Integral, a calculus adventure book held in the University of Waterloo’s Special Collections & Archives. My superpower is coming up with unique and creative solutions to really hard problems. I’m imaginative, original, and love working with others to build meaningful solutions. I’m looking to collaborate on exciting projects with talented teams. My goals are to keep growing, become exceptional at what I do, and continue having fun building and creating.

    Built an innovative, browser-based 3D modelling platform with my team at Hack the North called ShapeShift, which won Y Combinator’s $2,000 Unicorn Prize. 3D modelling software often has a steep learning curve and relies on clunky keyboard shortcuts and mouse clicks. ShapeShift offers a more intuitive approach to 3D modelling. ShapeShift uses your camera to detect real-time hand gestures to manipulate 3D objects. It also uses an intelligent AI assistant that can generate 3D objects for you.

  • Intern of Technical Staff at Cohere
