Dear Sir,
I carefully reviewed your project requirements and I'm available to complete the work quickly and professionally.
I'm very skilled coder (php, javascript, python) with previous experience with Ecommerce and CMS platforms (WordPress, OpenCart, Prestashop, Magento, Joomla and so on). I will code your application in python since it will perfectly fit with arduino. I need specs of any sensor connected to arduino and also I need to know arduino board version you need to use.
Project seem to be very interesting.
Please do not hesitate to contact me for any question and hopefully to immediately start working on your product.
Best Regards
Andrea
