Developer with over 30 years of experience working on projects of all sizes, with a “touch” of systems. I feel comfortable working on both creative/visual tasks as well as technical tasks.
I love programming, no matter the language, but I have the strange habit of using paper and colored pens more than the keyboard directly.
Having worked with many different Operating Systems, Databases, Programming Languages and the unique casuistry of each, has led me to have a series of guidelines and premises before starting a project:
- “Possible” means “Economically viable”
- There is no one-size-fits-all solution/technology (the Swiss Army knife)
- For every minute spent on planning and study, you’ll need 2 minutes less of development
- Errors and problems always happen, you must always take this into consideration, and foresee and define how to act
- The end user will do things you can’t imagine, try to imagine them beforehand, or at least be prepared for those “human behaviors”
- Test, test, test… (automated and/or manual testing)

My main task was to test and deploy new services, evaluating new technologies and achieving complete integration: Provisioning, Log management to our customer services platform, management system and monitoring system.
When a new service was needed, not existing, we created custom solutions. All team members (developers) formed small teams to determine the best and most efficient solution, in most cases solutions were hybrid (.net + Java, Java + PHP, .net + PHP, …)
In the R&D department I was in charge of management and maintenance of development servers: Windows, Linux, FreeBSD, NetBSD, Solaris.
Another task of my role was to feed our Data Warehouse with clean data originating from different systems: LDAP servers, Mail servers logs, Radius logs, Webservers log, FTP Logs, Accounting systems.
ReDOC: Internal webapp (PHP 5): An application to dynamically generate contracts (in PDF and Word) of services for our customers, so they always had accessible the contract (at the time of service acquisition) and subsequent versions (changes according to law).
Reports: Internal webapp (Ruby on Rails): Small application that allowed us to display in an organized way different data sources: Logs and statistics of the PBX, provisioning systems, management,…
CreaWeb: Customers app ( PHP ): Web application that allows users, through a Wizard, to create simple and manageable websites, which are automatically uploaded to their web space on Arrakis servers.
All Arrakis websites used MorcegoCMS, a small CMS developed by me (http://sourceforge.net/projects/morcegocms/ ) (outdated)
