All things tech at Columbia. Learn more.

The Application Development Initiative seeks to nurture student creativity and technological aptitude by creating a community and resources for student developers of all talents and interests.

What We Do

Cookies and Code

Every Wednesday night, ADI hosts Cookies & Code, where student developers meet one another, share feedback on code, and eat cookies.

Weekly Events

ADI hosts weekly workshops and tech talks, bringing professional developers to campus to teach students their expertise. In addition, ADI hosts student-run talks, during which students teach each other skills they have developed.


Every spring, ADI hosts DevFest, a week-long series of technical workshops culminating in a 24-hour hackathon. DevFest focuses on fostering community, and helping new developers end the week with a completed project.

Startup Job Fair

ADI hosts a yearly job fair in the fall for student developers to connect with New York tech startups in a low-key and casual environment. Last year we hosted twenty companies and over 250 students.
