Javify wins Rep. Dwight Evans’ 2025 Congressional App Challenge in Pennsylvania’s Third District
Rep. Dwight Evans has named Arnesh Das of Julia R. Masterman Laboratory and Demonstration School as the winner of the 2025 Congressional App Challenge in Pennsylvania’s Third District. Their app Javify is a personalized educational companion for AP Computer Science A.
When asked what inspired the creation of Javify, Arnesh Das said, “When self-studying for the AP Computer Science A exam last year, I had trouble finding websites or places with a variety of multiple-choice questions. Sure, there were a few, but they were all either very easy or really hard, and it didn’t really match the style of the AP exam. I knew that I was not the only one with this problem, as my friend and my brother who were both self-studying for the exam as well, could not find practice questions. As computer science is becoming more and more popular, I created Javify in order to help students who are self-studying. Javify includes a plethora of practice questions, and also has lessons that guide users through what they need to know for the exam. The questions are also very similar to the AP exam, resolving a major gap in self-studying for the AP Computer Science A exam.”
The 2025 Congressional App Challenge marked another record-setting year for the program. A total of 394 Members of the U.S. House of Representatives hosted App Challenges in their congressional districts, the highest level of participation in the program’s history. More than 13,800 students from across the country participated, submitting over 4,600 original apps focused on real-world challenges ranging from health and accessibility to education, sustainability, and civic engagement.
The Congressional App Challenge is an official initiative of the U.S. House of Representatives that encourages middle school and high school students to learn to code, explore computer science, and build practical technology solutions for their communities. Each participating Member of Congress selects a winning app from their district, and winning teams are invited to showcase their projects to Members of Congress, staff, and industry leaders at the annual #HouseOfCode celebration on Capitol Hill.
The Challenge is proudly bipartisan and reflects a shared commitment to expanding access to STEM education and preparing the next generation of American innovators for the future workforce. The program is a public-private partnership made possible through funding from the Broadcom Foundation, AWS, Infosys Foundation USA, theCoderSchool, Apple, and others.
The 2026 Congressional App Challenge will launch in May, and eligible students can pre-register for the competition now.
