Background

An AI engineering leader, cofounder, and University of Toronto lecturer building things people actually use. Currently the cofounder of XY SPACE, where I help companies design and deploy AI systems that actually work.

At Verto Health, I led a team of over 20 developers, fostering their growth while shipping complex healthcare software. That passion for teaching was recognized by the University of Toronto, where I became the youngest sessional lecturer promoted in the CMS department.

My technical work focuses on practical applications of artificial intelligence, and has resulted in two co-authored patents and two competitive AI awards.
