I am a product-focused software engineer with 9+ years of experience in native Android development. I am the author of two worldwide published Android programming 300+ page books and have been recognized by Google as the first (and only at this time) Google Developers Expert in Android in Pakistan. 

Working with many companies around the globe remotely for more than 6 years and with a comprehensive knowledge of mobile development and design (especially Material Design), I am an excellent communicator in English, an enthusiastic team-mate with an eye for simplicity, and passionate for writing beautiful, pragmatic code and documentation. At my previous company (Airlift Technologies), I had led a team of 8 engineers to migrate an old legacy code to modern Android development with the best practices such as MVVM, Kotlin, Architecture Components, and testing. The result was improved productivity and a faster roll-out cycle to our more than a million customers using the Android app to place their orders.

I have also been a passionate open-source contributor with multiple Android libraries under my name which are widely being used in applications by developers around the world. Being in the open source world has taught me the understanding and concepts behind SDK development and how to create the public APIs and interfaces which allows a great developer experience for SDK users. I am also a technical blogs writer with over 100 articles and share my knowledge with the community around the world through my public speaking at conferences like Droidcon, Android Summit, DevFest UK, etc.
