Air Guardian wins Rep. Sheila Jackson’s 2023 Congressional App Challenge in Texas’s 18th District

Rep. Jackson has named Sarvajit Jonnalagadda, a 10th grader at Klein Cain High School, as the winner of the 2023 Congressional App Challenge in Texas’s 18th District.

When asked what inspired the creation of Air Guardian, the student said, “Solving global warming. When said in those terms, the challenge of addressing climate change seems like a daunting, almost impossible task with complexities that are difficult to even grasp. To meaningfully take action on such a large problem, I immediately began anchoring to data. Far too often, the discourse around climate change revolves around large macro-level calls to action and emotional appeals. When ideating around how to implement a solution, I felt that an inverse approach focusing on micro-level, data-led solutions would allow a populace to see the immediacy of the problem we face. Additionally, working with a variety of data allowed me to truly understand the scope of this problem and add concrete information to truly isolate the root cause of environmental damage. As such, I believe that using technology to visually represent pollutant data in the form of a mobile application is the ideal methodology to address this chosen area of focus: air pollution. However, when constructing this application, I realized that simply presenting the data to users, while effective, needed to be paired with concrete medical information to empower users to take matters into their own hands and decide for themselves and their families how to address the levels of pollution in their area. As such, this app combines medical science along with technology to truly construct a real, and use-functional solution. This combination is especially powerful as the technology puts science at the fingertips of users via a mobile application. Science on its own is difficult to digest for the average person and technology on its own becomes unfocused without material information to support it. The merging of these two ideas within STEM allows for the clear articulation of science to the average user while encouraging interaction via an engaging application. Through these various methods, I was thoroughly inspired by global warming to solve such a crisis.”

This year’s Challenge saw an unprecedented level of participation, with 374 Members of the House of Representatives hosting competitions, surpassing the previous record of 340. A remarkable 11,334 students from across the United States competed in this year’s Challenge, marking an impressive increase of nearly 1,000 participants compared to the previous record set in 2019. The enthusiasm and creativity these students display is a testament to the growing interest in technology and signal a bright future for American innovation. The surge of ingenuity continued with a whopping 3,645 original applications flooding in, nearly a thousand more than the previous year’s high. This remarkable growth showcases the exceptional talent and innovation within our nation’s youth.


The Congressional App Challenge is an official initiative of the U.S. House of Representatives, where Members of Congress host contests in their districts for middle school and high school students, encouraging them to learn to code and inspiring them to pursue careers in computer science. This resounding show of bipartisan support emphasizes the critical importance of STEM education in today’s rapidly evolving world. Each participating Member of Congress selects a winning app from their district, and each winning team is invited to showcase their winning app to Congress during our annual #HouseOfCode festival. The program is a public-private partnership made possible through funding from Omidyar Network, AWS, Rise, theCoderSchool, Apple, and others.

The 2024 Congressional App Challenge will launch in May of 2024, and eligible students can pre-register for the competition now.
