Hi Sr,
I'm Teachnical and Electronic engineer with more than 15 years of experience.
I'm Argentine, but now I'm near to Reggio Emilia, Italy. I have a good english for telephonic conversation.
I can solve the problem that you have. As you can see in my portfolio, I was working in the past in a naval company, designing equipment and giving technical service. I know how to read and understand circuits.
Please any question, feel free to contact me.
Best Regards.
Eng, Juan M Garin
