Photo Uploading & Editing app + Website: Redevelopment & Improvements

I am looking for someone with experience in handling digital photos web/mobile development. Preferably someone who has an interest in Photography, and an understanding of photo editing and design will be a plus. I have an existing app on iOS and Android ; Postalgia Prints. It allows users to upload photos and make payment through paypal , and we print the photos and mail to them. Currently only available in Singapore. I am currently looking for someone to develop on the existing app to add various features such as: 1) overseas versions (difference being address fields and currency) 2) quality fix. currently my photo upload process shrinks the photo size significantly, causing my prints to be of lower quality. 3) account creation and social media integration (facebook , instagram) for accessing personal details, and in the future syncing of photos from social media as well 4) multiple addresses 5) photo edit filters 6) feedback button 7) UX changes 8) additional photo product size (we currently offer photo prints in 3 different sizes) I am also looking to improve the website [login to view URL] with following features: 1) instagram feed integration .. show latest photos of #postalgia or similar 2) design revamp of website 3) inclusion of testimonials , and static page to showcase our products Thirdly, I will need some improvements on my backend; 1) currently have an error with duplicate photos being created in my backend from certain larger orders. 2) Generation of receipts for orders 3) Revamp customer management system for better searchability/categorization , for easier follow up on existing customers. better link between customers data and order data. filter out junk orders (all orders, even non completed ones are recorded).
