Hi,
I have checked your requirements and after that i have checked twitter adv API carefully. I found there are options to manage adv campaign through API. also there are options to set target criterion ex. location, interest, keyword, gender etc. So i think its possible to develop such thing that you are looking for. S i am confident that i can do your job perfectly.
I am very much interested to work with you to make a good relationship for long term opportunity.
I have experience in working with native android, php, codeigniter/laravel framework, mysql, mariadb, jquery/angularjs/vuejs, amazon web services, cross-platform framework ionic for both android and ios, redis, html, css, bootstrap, stripe, paypal, facebook, twitter etc.
I am a Web and Mobile app expert with over 5 years experience dealing with small to large scale application. Although i am new in freelancer.
So if you give me a chance then i will try my best to prove myself and delivery you the quality work that meets your needs perfectly. I will work until the complete satisfaction from you.
At least wish to get a reply from you.
Thanks
Al Amin
