Hi, I am an Electrical Engineer with experience in Electronics circuit designing. Recently I completed one Wifi Based project(Schematic plus PCB) and one GSM based project. If you want I can show you Images of project. Can you please contact me so that I can ask you some questions regarding this project. You are not seeing that projects on my profile because I just join one company as an Hardware Engineer and they don't allow me to take outside projects thats why I don't ask for review from my client. Please contact me so that I can show you sample of my finished projects. Reason for bad review: I completed 16 power relay project(Check it into my profile) but due to some payment issue I have to stop my project from delivery as you can see it into my profile rating. Client didn't even create milestone. At starting he agree to pay me before project delivery but after I finish the project he start avoiding my messages so this force me to stop my project from delivery. I hope you will understand. I lost 85$ in that project.
