The mobile engineering book that every app developer should read.
Improve the way you work and strengthen your skills as an experienced mobile engineer.

Don’t just be busy. Deliver.
Stop getting stuck in a difficult codebase that’s hard to modify. Learn how to keep a growing codebase nimble and easily adjustable so that you can focus on delivering features.

Learn to be more resourceful in your engineering practice when working with constraints, such as dealing with limited information and available time.

Having this newly acquired knowledge will allow you to make swifter and smarter technical decisions for your team or at your company.

Gain knowledge that you can apply instantly

You will cover the process of creating a feature from scratch — all the way to delivering large-scale solutions.

Each step of this process is explained in depth and in detail; This approach is tailor-made for the mobile engineer.

The book’s process strongly resembles those that exist in a real-life working environment, whether that’s a small team or multinational enterprise.

By making use of this practical approach, it allows you to learn tangible skills and knowledge that you can apply to your own work the very next day.

Strengthen and improve your skillset

System Design is becoming an increasingly standard aspect of the interview process and a responsibility of mobile engineers in terms of their expected skillset and competencies.

Use this book to build on your current skills to improve your day-to-day work and prove that you can handle difficult requirements for mobile apps.

Confidently move away from building small features by showing that you can deliver app-wide solutions.

This early release edition is an unedited work-in-progress. You can already read 14 chapters and you will receive new chapters as soon as they are finished. When the book is finished in 2024 / 2025 (estimated), you will receive the full, polished, edited version.
