Hello, I am Anthony from Sri lanka. I have 7 years of experience in the filed and I am very much interested in your project. Why you should hire me ? * As a full time freelancer I have my own PCB fabrication work shop and testing lab. So there is no problem doing live tests with you after the device has been developed. * My workshop is equipped with CNC machine, FDM 3D printer and DLP 3D printer. So there is no problem designing and printing plastic parts you required. Please contact me if you are interested. Thank you Anthony
