    Hello, I'm Dilruba. I'm 23 years old. I'm studying Computer Science in Turkey. I love programming and web design. But I'm afraid to take a step. Because I think everyone is better than me. I haven't had the opportunity to work in this field yet. Because I haven't done many projects in this field. That's why I'm looking for a job. #freepalestine
