Leaded several small to large-sized cross-platform mobile applications with a backend. Additionally, participated in an R&D project about AR (Augmented Reality).Cross-platform mobile applications are implemented in Java using Phonegap and GWT (Google Web Toolkit). Backend applications are also implemented in Java using the Spring framework. New technologies and methodologies are adapted incrementally in each project to increase productivity. Accordingly, we used Maven as a build tool, Hibernate as the persistence layer, Orika to convert domain objects to DTOs and vice versa, GWT editor framework for form-like screens, EHCache for annotation-based caching, Spring Security to secure our websites and web services, to enable automatic mobile logins, and even for securing specific domain objects via ACLs (Access Control List).

Karga Games has developed and published the first true 3D chat platform in Turkey, called in-short Karga (which means crow in Turkish). In this platform, similar to multiplayer games, users can move around in 3D places, see and talk to each other, change their appearance, and interact with the environment and each other (such as dancing and kissing). Sky Maze 3D is a high-quality 3D Android game developed by Karga Games. On March 28, 2013, Sky Maze 3D was promoted by Amazon as the "Free app of the day" and reached 1st place with almost 80k downloads in a single day.
