We are looking for a skilled programmer for devoloping two layers of software system for a new payments startup..
1. Application for androids and iphones which will have to connect to the server and communicate with it. You need to program a special library for live (no picture taking) camera recognition of our own "qr" code (special circular code). After the user approaches this code with phone and camera recognizes it, it pulls more data from server, like recipient, value to transfer, info about product and other purchase details. User then clicks on authorize button and
the funds have to be transfered from his credit card to our merchant account and then on to the final recipient (This is already 2nd layer). On the mobile app side option will have to be that user also authorizes every transaction with a PIN code. Mobile app should also have the option to add more credit cards, change data and pull transaction history or logs from database with additional info. It would be great if this could be done on a single platform which could be scaled to both systems (android, ios) but if not we would opt only for one in the begining.
2. Second layer is the php backend program which is quick and critically secure. Programmer will have to set up a solution for transactions through communication with mobile apps. This backend will store personal data and credit cards of our customers. Another critical feature is connection with api of our merhant account provider. Backend will in essence receive data from apps and move money from credit cards to our bank account thru merchant account. It will have to assure that funds are then moved to other bank accounts (api), fees are reserved and positive balance on our side always kept, risk-marked accounts are sorted out and rejected. The larger part is backend, but there will also be a little php interface where circol barcode images(jpg) will be generated from a random number assigned to merchant and inserted into database.
Finally I would like to ask that only those who are experts at building fast, mission critical, very secure php applications and also have knowledge of programming on mobile platforms with insight into camera and imaging libraries. This is only the beginning, because there will be a lot more work in the future with the possibilty of partnerships or stronger commitments.
p.s.: sample of circular code is attached..
