Rep. Jim Costa announced on Wednesday a Selma High School student as the winner of the 2025 Congressional App Challenge for District 21.

Natalie Bonilla’s app — Community Support — compiles critical hotline numbers and community support resources into one centrally located app, providing Central Valley residents the ability to access critical assistance during times of need.

People in crisis can find help hotlines and support groups for suicide and mental health, child protective services, substance abuse, law enforcement, LGBTQ, substance abuse, the elderly and more.

 

Bonilla, a Selma High School senior, developed the app for both iOS and Android platforms, aiming to reduce the stigma associated with seeking assistance and to make life-saving information accessible to local members of the community.

 “I come from a family deeply involved in social services, which motivated me to continue helping others. I’m very grateful for this opportunity and honored to have been chosen as this year’s winner,” Bonilla said. “I was completely shocked and didn’t expect it at all. My teacher encouraged me to apply, even though I had a lot of doubts. When I received the news, I was incredibly happy.”

Bonilla constructed the app using the coda language Java, which saw her navigate technical challenges, including adapting the app’s design across different devices. Through the development of the app, Bonilla gained deeper appreciation and understanding for the complexity and time required to develop a fully functioning app, according to a news release from Costa’s office.

“Natalie’s app demonstrates how technology can be used to strengthen communities and support those who may be experiencing difficult moments,” Costa said. “As one of America’s future leaders, Natalie has already shown creativity, persistence, and a strong commitment to service.”

The Congressional App Challenge challenges middle and high school students annually to explore the fields of coding and STEM (science, technology, engineering and mathematics), creating original apps and reaching students from diverse backgrounds across the country.

“I’m proud to recognize her achievement and look forward to seeing what she accomplishes next,” Costa said.
