Please help to find mistakes

I wrote small text and i ask to help me make it without mistakes. Here it is:
"I have never done a bachelor’s thesis, but I did several course projects. I like programming and therefore the most memorable course project for me was one in which I wrote the program. This course project was titled “Java technology for distributed computing”, and the subject was called “Parallel and Distributed computing”. Using java, I wrote a program that was installed on multiple computers. Each of them executed a part of one task. The main computer received the results of calculations from the rest. It was a very interesting project, which took me a long time to do. In addition, it helped me to learn the basics of web programming in which is my scientific interest. I learn several programming languages. They are HTTP, PHP, java, c++ and others. I even have a web site where I tested my first project. I believe that finishing the master’s degree will give me a new level of understanding programming languages. So, acquiring a degree is the best way to improve my knowledge. Also, a Master’s degree is more valuable in today’s job market than bachelor’s. Considering the topicality of my specialty, it will increase my chances of getting a good job. There is a high demand for programmers and also more number of opportunities available for them, especially with master’s degree. There are many companies specializing in advertising, sales, tourism, and there are people who get their information from different sites of these firms. Their number is increasing and the demand for programmers is also increasing."
