AppDev Hack Challenge

Whether it’s developing a mobile app, building a robust backend system, or designing a user-friendly product, we strongly believe that the best way to learn something is by doing. That's the foundation on which we've constructed our courses. We want students to not only gain practical skills in design or development, but also to leave the course with tangible projects they can showcase on their resume or portfolio.

With 150+ students each semester, the semesterly AppDev Hack Challenge allows for students to have this opportunity. The AppDev Hack Challenge involves students across all our courses (iOS, backend, and design), and each group of 3-4 students works together to create a functional, polished app to showcase by the end of the semester. 

Participating in the AppDev Hack Challenge is the required final project for students enrolled in either the iOS or Backend courses, and is highly encouraged for students enrolled in the design course. As an added incentive, we have sponsored challenges with prizes, and all participants have their resumes sent to our corporate sponsors, which include Airbnb, Amazon, Bose, Facebook, Google, and Microsoft.
