33 Engineering Challenges of Building Mobile Apps at Scale [Beta]

I've been noticing how while there's a lot of appreciation for backend distributed systems challenges, there's a lot less empathy for why mobile development is hard when done at scale. Building a backend system that serves millions of parallel customers means building highly available and scalable backend systems and operating these reliably. But what about the mobile clients for these systems?

The book is being currently being written and is in beta: by purchasing this content, you'll get access to updates, until the final version. By pre-ordering this resource, you get earlier access to the content.

Mobile learnings from my time at Uber - 4th Jan 2020 

6 mobile-related learnings from my 4 years at Uber.

Growing as a mobile engineer

10+ pages on growing to senior and above levels as a mobile engineer, at tech companies. During my time at Uber, I've helped with 10+ mobile engineering promotions in my org, 3 of these to above senior levels. I've sat on multiple promotion committees and mapped out promotion paths all the way to staff for iOS or Android engineers. How do you break the senior and above glass ceiling, when you specialize in iOS and Android?
