I will use nodejs + javascript ,angular 1.x and database will be mongodb ,given that those API services provide front end javascript or backend node SDK for using their api .Also estimated time is 15 days, given that I don't know much about the API's you want to integrate. Also I have experience in php mysql ,in case your website is in php ,I still fit that person you are looking for.I look forward to your reply .Thanks for considering my bid.
