Dear Sir, Madame,

Thought my whole life, I have been questioning my self, will I be able to impact and change the world? do I have the power to improve it and make it better? I found the answers for all those questions the day I chose to become an Ethical Hacker.

Holder of a bachelor's degree in computer science, currently first year master student in security of informatics systems, I request my admission to your establishment to pursue higher education in master cyber security.

My undergraduate studies provided me with high knowledge in different aspects of computer science, specially high level programming, databases and a deeper understand of low level programming and exploitation systems. My Bachelor's End Project titled "Malware study and development" Allowed me to acquire know-how on malware and their creation. In addition as an autodidact person, I developed basic knowledge on the hacking field, like digital forensic, buffer overflow attacks and how to evade some of its protections, and the use of pen tenting tools, then I specialized my self in reverse engineering and malware analyses. To improve my skills and knowledge, I participated in many Capture The Flags competitions in my home country and online. I also participated in development competitions, like imagine cup where I created a 2D android game, and StartHack which is an innovation competition where me and my team made a system for intelligent homes.

My favorite programming language where I excel are C, Python and Assembly, I work on Linux and I use GIT to manage my projects.

Being attracted and enthusiast, I wish to attend METU's cyber security program because of its high level of education and the courses provided which focuses deeply in the domain for example malware analyses, social engineering, forensic.That will prepare me to start a penetration tester's career with high expertise.

In the hope of a favourable outcome, please accept, Sir, Madame, the expression of my deepest respect.
