I am planning to build a mobile application (android and iOS), but I am confused. my idea is simple: user takes a photo using her/his mobile phone, the photo is sent to the server, server checks if the user has registered or not (user authentication), if he/she is a registered user, his/her photo would be processed (some image processing steps) and finally the processed image would be sent back to user's mobile.
I know I should have a frontend and a backend. what programming languages should I use? I have googled a lot but yet no success. someone suggested using Laravel for user authentication but I am not sure if Laravel could handle the image processing steps as well.
Any help is appreciated.
Being unaware of your experience and preference of programming language, I recommend to start with the Django framework, which is based on Python and receives a growing interest after its release in 2005. Probably the most famous project using Django is Instagram, whose core functionality is close to what you are after.
A good example project for you to start with can be found here:
