Hello Sir/Madam,
I am Anthony Perera from Sri Lanka and I have multiple degrees on Engineering field.
Why you should hire me ?
* I am a FULL TIME freelancer and once a project is awarded to me,all my time will be dedicated to
that specific project so you will get fast and quality work.
* I have been in the field of product designing so if you are developing a commercial device I can
help you to design it at very low cost and also can get into contact with Chinese manufacturers
who I work with. Very reliable and fast.
* I have my own PCB printing facility and also a workshop where I can design and manufacture
any number of samples/prototypes. In that way you don't have to find some one else to test my
work.
* My prices are very fair and can be negotiated all the time. I am very flexible and very
understanding.
You can see my reviews. Check my profile. See for your self.
