Platform: Linux
Tools: C/C++, Eclipse, cmake, Sublime Text2
2012, Fixing Samsung HDMI driver for SoC Exynos

Platform: Linux Kernel
Tools: C, Eclipse, Sublime Text2
2012 to 2014, Interactive TV for Android
I’m a team leader of this project. For now, in my team I have two developers. At the beginning this app was developed by me from the ground. The whole UI part is in the cloud and delivers by h264/AAC to the clients and the core feature of this client is to be very responsive on user’s touch. Another target of this app is to be adjustable for TV screens and support different TV refresh rates (50Hz & 60Hz). And the third thing which we supported on the client side is adaptive bitrate to be ready for the real world issues (it works for Android devices 2.3 & higher).
This app uses the whole capacity of the Android multimedia subsystem (OpenMAX, OpenSLES).
Platform: Android
Tools: Eclipse, Intellij Idea, Android SDK, Android NDK, Android Compatibility Library, JSDK 1.6, Gradle, Google Protobuf

The main problems that could be solved by this engine are the unwanted disconnects, slow response times, and underutilized systems. The engine analyzes all aspects of users’ environment, from edge to core, and then creates optimum configuration profiles for all of user systems. The developed engine supported a completely automated method of applying real-time optimization of the SharePoint, Exchange and VMware implementations.
