$15-25 USD / hour

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.

Beside I have been working as IT engineer since the very start of the internet, back in 1995 when I worked managing the small team that developed the first "internet portal" of Telefónica: TeleLine. After working on the TeleLine project, I had the opportunity to work with payment gateways in the same context: as an employee of Netscape, I developed for Telefónica the first Spanish intenet payment gateway, using PRICE, the Spanish implementation of the ISO8583 protocol used by SEMP (Sociedad Española de Medios de Pago). It was implemented in C language, and I was the only developer in that project. Beside that, what I think qualifies me at least as a candidate to be taken into accunt...I am Spanish, so I speak Spanish as native language. I look forward to hearing from you, Eduardo G.
