Take over existing PHP project - analyze code, document, and enhance

We have an existing payment processor gateway written in PHP (OOP) and MySQL. This processor gateway has an API so that shopping carts can be connected to it and then it brokers transactions to various banks via their respective APIs. There is also logging and reporting features, settlement features, etc. It is a somewhat large platform. The task is to analyze and learn the existing code (the current developers are no longer available), document how the code works (modules, execution flow, etc), then begin maintenance and enhancement tasks as directed by us. Given the unknown scope this project will be best done on an hourly basis. Person doing the work must be very familiar with reading and analyzing other people's code, debugging and testing, etc.

Habilidades: Javascript, MySQL, PHP, Arquitetura de software, SQL
