Hi tsunny,
It is a bit tough to predict the role of extracurriculars in a profile evaluation -- while it is definitely good if that area is strong in your application, it's hard to predict the overall impact if it is weak. Putting that aside, your academics appear competitive for Haas, but you will need to clearly differentiate yourself from the engineering applicant pool to ensure the admissions officers remember your application.
Best of luck,
Daniel Richards
