At the first time, I was associated with Javier Cárdenas and Manuel Monarrez for the creation of a new platform that allows store bills in an automatic way processing the (CFDIs) issued by different suppliers or companies.
The project was called RexBackup and it was about create an e-mail account for each client, it could receive the XML file of the bill (including their corresponding PDF) or a ZIP file with both files, so the system could process and store it in a secure way inside a digital compiler, in this way, we could show a list of the issued / received bills each month.
While Javier was in charge of the project finance and Manuel of the commercial aspect, I was in charge of the complete software building on each one of their versions, from the planning, analysis and optimization to the coding and maintenance.
The project was build on Google App Engine and was coded in Java, working with the frameworks: Spring MVC, Tiles and Spring Security and my own encapsulation libraries for Objectify
Based on the first project, there was a commercial version called 'Recopiladores Digitales¿, it was builded using the RexBackup library extending their functions.
As principal features, it counts the ability to limitless store files on cloud, just like DropBox
Even when the original domain it's expired, it's possible found the demo version, to get access, use the: User: demo and Password: demo
I build a new project called SatMan based on the RexBackup library, which promised to perform the accounting of each client, and allow the bills issue and not only their storage. For this, I build new modules.
During this project, there was more people included on the development team, so I took care of training and directing.
