Apple's annual Worldwide Developer Conference brings together app developers from all walks of life, and the youngest to make the trip to San Francisco this year was Anvitha Vijay, a grade four student from Mount View Primary School in Melbourne.

Anvitha, now nine, began coding at the age of seven. She wanted to make an app that would help her younger sister – then two – to identify animals. Two years later Smartkins Animals, an educational app aimed at kids aged five and under, made it into Apple's App Store. The iOS app was good enough to win her one of 350 Apple scholarships for young coders to attend WWDC. She was one of eight in Australia.

"I'm learning a lot already, there's so many smart people to talk to," she told Fairfax from the conference.

"San Francisco is great – the weather is even weirder than Melbourne's!"
