Mr. Khawaja Muhammad is an expert I would highly recommend to anyone interested in his skills and expertise. He has helped me a great deal on a challenging project. The project was regarding a prototype that had to be made from scratch. He has approached the challenges with great engineering analysis and always asked for detailed and well-thought input about the idea for the project. Aside from his expertise, he is a patient, and an understanding person ready to explain and help with the technical aspects of the project. This has been my first time using the Freelancer platform and I am happy that I had a chance to cooperate with exactly him.
