    Engineer

    United States - Last active: 10/31/2012 - Tests: 3 - Portfolio: 1

    Over the last 3 years I have developed a variety of hardware and software in C, C++, and C#. My core competency lies in design and debugging of small to mid size programs. I am seeking opportunities to build apps/programs from the ground up for you or your business. I have studied cutting edge technology with hardware as well as software. I have picked up my trade extremely fast. My portfolios below demonstrate my robotics work. I taught C++ and Java at a summer camp last year and it really pushed my skills and abilities! I am now much more confident in both languages. I can do iOS programming, but I don't have a mac at the moment. I've worn lots of hats in my day any other questions just ask.

He took it on with enthusiasm. What he didn't know he learned on his own. I did not have to micromanage him at all. He kept me updated with his progress the entire time and responded quickly any time I needed him. His expertise in MATLAB and Partial Differential Equations was very impressive. I enjoyed working with Muhammad and have complete confidence in him when he says he can complete a project. He was the perfect freelancer for me. " Testimonial#2 "He is amazing freelancer, who goes beyond the task to help. If you don't work with this freelancer, it's your lost.
