Good Evening Sir,
Here is Michele Cimmino from Italy I'm the owner of an individual software firm.
I can provide more than 10 years of exp and passion in IT and web-mobile technologies.
About your project i totally agree with you that the developer you are going to hire must be an expert.
What I can say is that I started to develop in PHP when I was only 15 years old. 10 years later, the way to code in PHP is significantly changed and I have been keeping up with the times to be at the forefront. According to the principles of the software engineering I can provide you also an object oriented, modular, scalable approach in the software architecture but also in the development.
I know how to interact with css3, html5, mysql, xml, json, ajax, javascript, jquery and any other metalanguage, front end and back end language.
The quality of projects that I product is the strength of my company, because software, per definition, is the most maintainable and obsolescent product that exists.
Pls take a look to my CV on my profile to understand the quality of works that I made.
As you can see I passed with good marks a lot of exams on freelancer, this is a garancy of my skills.
Feel free to contact me, anytime, for any question.
Regards, Michel
