Top 10 Solution Challenge Winners

Check out the 2020 Solution Challenge winners here. Thank you to all the Developer Student Clubs that participated and helped make this such an awesome experience. Also, a big shout out to all the Google Developers Experts (GDEs) who supported a number of teams with mentorship. We really enjoyed going through all of your creative solutions using Google technologies. We will be hosting a Virtual Demo Day end of August to showcase these solutions to everyone around the world!


What is the Solution Challenge?

The Solution Challenge is an annual contest presented by Developer Student Clubs (DSC) that invites students to develop solutions for local community problems using one or more Google products or platforms.

Please see full terms and conditions here

What are Developer Student Clubs?

Helping students bridge the gap between theory and practice, Developer Student Clubs are university based community groups for students interested in Google developer technologies. Students from all undergraduate or graduate programs with an interest in growing as a developer are welcome. By joining a DSC, students grow their knowledge in a peer-to-peer learning environment and build solutions for local businesses and their community.

There are over 800 DSCs across the globe. Check out if there is one near you here.


Join the Solution Challenge






Form a team & start building. Your local Developer Student Club will be hosting meet-ups to help!



Submit your solution and a 2 minute demonstration video on how it can be used. See an example from the 2019 challenge.



Partner with your local DSCs to participate in or even organize a local DSC Demo Day - an in person event showcasing your solutions to your community. 

Get inspired


Here’s a great story of Developer Student Group member Destiana Choirun Nisak, who leveraged her local Developer Student Clubs community to build a flood alert app, L-Flood. A Bojonegoro Village, Indonesia native, Destiana has seen and experienced how the floods affect her community. While enrolled at PENS University, Destiana met ‘Dana’ Surahutomo Aziz Pradana and they set out to create a solution that alerts those in the surrounding areas when they know the river is going to flood. Through the app, local authorities can send alerts and find the closest safe point based on their location. 

Meet David Asem, Developer Student Club Lead in Ghana. Hear David discuss the challenges for first year students at Kwame Nkrumah University of Science and Technology in Kumasi and how their DSCs solve for accessibility at a local mall.

At first, Hastu thought she couldn’t become a developer because she is hearing impaired. Then, she met Tesya at a local Indonesian Google Developer Student Club, and Tesya took the time to mentor Hastu in Android technology. Fascinated by what she learned in her DSC, Hastu dedicated her time towards building an Android app that helps facilitate connecting blind students with sight volunteers. Hastu aspires to become the CTO of an Indonesian start-up in the future. She continues to build apps, and solve local problems for her community.

Starting a project is the hardest part. 

After conversations with hundreds of college students across the globe, we were able to understand what makes successful solutions. Here is a four-part framework focused on solving for a specified problem you can leverage.
