Design &Engineering

Fluent in systems. Precise about the details.

I'm George Mavroidis. I design and build products end to end, happiest in the edge cases: the empty states, the error paths, and the frictions in between. Off hours, I build small tools and see how far they go.

George is a designer & engineer in Toronto – equally at home in a design file and a terminal, and a little obsessive about the seams where the two meet.
