Design craft meets engineering prowess

I'm Kartik Iyer, a Toronto-based designer and builder.

I've dedicated over 12 years listening to customers and cross-functional teams, turning their roughly articulated ideas into coherent products.

I thrive in environments of high agency, urgency, and uncertainty. I invest care into the details that make software feel considered.
