About this webinar

This jam-packed hour will let you learn more about the challenges engineers face when building iOS and Android apps at scale, and common ways to tackle these.

Come join Gergely Orosz and his peers as they share a journey starting with an idea for a mobile app which then grows through stages becoming one, used by millions, and developed by hundreds of mobile engineers.

The session will lead into a live Q&A where our panel of experienced engineers share their insights on these topics, while answering questions from the audience.

Who should join & what you'll learn

You'll walk away with practical insights on what the main challenges are for each growth stage, and common approaches teams use as they scale up apps.

This session is for every mobile engineer, who wishes to learn about modern app engineering approaches and for all those non-mobile engineers and managers, who wish to build empathy and appreciation for the complexity of world-class mobile engineering.

As a bonus, attendees will also receive a complimentary PDF version of Building Mobile Apps at Scale: 39 engineering challenges, brought to you by Bitrise.
