Hi! My name is Arif, I am a Automation Engineer, Mechanical Engineer and Electrical Engineer. I am TOP RATED Mechanical Engineer with over 7 years of experience working on most demanding projects on the international market and I made over custom machine projects. The Machine Design should be imoressive, intuitive and easy to use. But most importantly, design must suitable with customer expected. I take on a limited number of projects at one time. This quality control means I can give each one exactly what it needs –­ focus and time. Since customer satisfaction is my first priority, I make myself available for conferences and collaboration regardless of time. Essentially, I always go the extra mile. I always put myself not only in my client’s shoes, but also in the shoes of the end user. Every project has its target audience with its own needs, expectations, taste etc. I use empathic design techniques throughout my process in order to reveal the values and aspirations of users. --- SERVICES I OFFER 1.
