Full stack engineers have skills in data structure and algorithms, frontend designing, architecture designing, database management, API designing, performance testing, code review, updates, and test management.

There are many advantages of having a full-stack engineering team instead of a separate frontend and backend engineering team for web app development:

• Saves project cost and time.
• Enhances productivity.
• Complete understanding and ownership of the project.
• Faster bug resolution due to understanding the complete system.

Mobile App Development

Mobile application development is developing applications for smartphones, tablets, smart TVs, and smartwatches, most commonly for the iOS and Android operating systems.

Nowadays, mobile app development is mainly of two types: native and hybrid. A native mobile application uses platform-specific frameworks and programming languages, like Swift/Objective C for iOS or Java/Kotlin for Android. In contrast, a hybrid mobile app combines the elements of a native app and a web app that can be compiled to run on iOS and Android.

Along with the programming language, an excellent mobile app developer must understand and consider screen sizes, hardware requirements, OS integrations, and mobile app testing tools like Appium.
