Clearing the noise with a user-centric, research based design methodology so the signal can shine through.



My desire is to thoroughly understand the way diverse users interact with products and not create only for their needs but create for their delight as well.  I am looking for a position that challeges me to fuse a strong design aesthetic with a user-centric, research based methodology structured through research studies, user testing, statistical analysis, and customer feedback.

Chaim’s last name is UX. I’ve worked with Chaim on many projects and was amazed by his intuition and attention to detail, and he never loses focus. The user is in his conscious at all times.

As a designer it is important to grow and evolve, and Chaim Sash is someone I’ve personally witness grow a great deal over the past year. From his earliest work to his most recent work, a progression in applying user-centric design principles was apparent. Chaim participated in several large scale projects, including the most valuable “check out” process which all paying customers must use. His designs, functional specifications and attention to detail, all the while advocating for the customer in every stage, were first class. Lastly, Chaim’s personality is well suited for collaboration. He knows when to pick battles and stand his ground, and when to realize that in all projects, compromise to the vision is par for the course

When it comes to interaction design and usability, Chaim just “gets it”. He is on the ball, takes into account all user scenarios and accounts from all angles before they become problems and bugs. Chaim is a real asset to any design team, and I highly recommend him.
