Sir,
I am an engineering computer Science student willing to work on your project.
I have designed a number of tutorials on various programming languages such as C,C++,JAVA,Python, PHP etc. before. Since I am new to this Freelancer.com website, i can give you no proofs of my work. But i can assure you i can complete the project on time and within the budget.
I guarantee 100% efficient and error free tutorials,pdf(s).
Thanking you.
