Seven-year-old Zora Ball has become the youngest person to create a full-version mobile video game application.

The Philadelphia native presented her new app at University of Pennsylvania’s “Bootstrap Expo,” reports the Philadelphia Tribune.

Ball attends Harambee Institute of Science and Technology Charter School, located in West Philadelphia.

Harambee is where Ball learned the Bootstrap programming language through the after-school program STEMnasium Learning Academy.

The STEMnasium program is 48 weeks and also teaches young students Mandarin Chinese.

“I am proud of all my students,” said Tariq Al-Nasir, science teacher and founder of the STEMnasium program.  ”Their dedication to this program is phenomenal, and they come to class every Saturday, including holiday breaks,” Al-Nasir told the Philadelphia Tribune.

Ball even proved to people attending the “Bootstrap Expo” that she was the app’s developer by reconfiguring her application upon request.
