Among the thousands of developers attending Apple's annual Worldwide Developers Conference (WWDC), Anvitha Vijay holds the distinction of being the youngest attendee. The nine-year-old from Melbourne already has two apps to her credit and ambitious plans for developing more.

Vijay is attending WWDC after being selected for Apple's scholarship program. Her focus has been on developing educational apps for children, which are inspired by her toddler sister.

Her interactive Smartkins Animals app helps kids identify over 100 animal names and sounds, while Smartkins Rainbow Colours is designed to help young kids learn about colours.

The Indian-origin Australian student taught herself how to code when she was seven, using YouTube videos and online tutorials. Her first app, GoalsHi, was built during the summer holidays and won a $10,000 student prize at the OzApp awards in Australia in 2015.

“I want to be a top entrepreneur in the world,’’ Vijay said after her win last year.

For now, she is travelling with her family from Melbourne to San Francisco to attend WWDC and hopes to meet Tim Cook during the event.

“Coding was so challenging,” Vijay told Fortune recently. “But I’m so glad I stuck with it.”
