Hello Sir,
Glad to see your project on Freelancer.com and and the good part is this makes us connect here ;)
To start off, let me introduce myself to you, I am an Adobe Certified Developer with more than 10 years of experience working across the globe, and the language I use would prove the same (just in case, as many have this common communication issue)
Talking straight to the point, I have developer a couple of similar working apps and it would a matter of pride to work on this with you.
Following would be the benefits which make me stand out:
1. Availablity of around 12-16 hours a day
2. Sharing of messenger ids for faster communications
3. Located 5.5 hours ahead of you, so we have most of the work ready before you start your day
4. Am working on almost all technology you mentioned since past decade now.
5. Command over language.
6. I can do a small demo for you to win your vote of confidence.
Please let me know if you need to look into the site I have which resemble your requirements. Will be more than happy to assist you on this.
Looking forward to work with you,
Thanks,
Bhavesh
