In continuing this trend now beginning to internalize in no specific areas of my studies as they are CSS , HTML , PHP , C + + , JAVA and Android. I have a high work ethic implying dislike wasting time or have other recreational activities in the workplace, which is a low mental challenge during the day. This is also reflected in the face with the same energy as both pleasant activities less conspicuous activities in which the worker is required. Downtime at work and try to avoid it if no other attempt take out time to study or read about topics of interest to help me improve or develop as a professional in the area of Information Technology and Telecommunications.
