About us

Team Chartreuse is formed by a team of students studying payment systems in Human Factor Interface Design, a class from Olin College of Engineering.


Yifan Sun: the overnight Java guru (well, more like overweek).


Chujiao Ma: the webmaster (most of the time).


Ben Salinas: the design ninja (with ridiculously small 8.9 in laptop).


William Yarak: the man with ideas (and an iPhone).
