Hi there! I am gone through your requirements. I am ready to do this job, but I need further info. I am working as a professional Mechanical Design Engineer.
I worked on designing different machines like Mini lathe that has a spindle runout of 0.0002 inches (it's in production right now) and also did some fully automated machines like Mail tray transfer unit (the client is USPS) and Dock To Ledge Transfer Cell (the client is also USPS), and I've also just added a 7 months project in the portfolio, a mechanical electric gripper which has a rotary and swiveling unit.
Check out my profile and message me if you want more info! hope to work with you.
