Experience as an user of several Operating Systems including Mac OS X, Mac OS 9, Windows, Linux, Solaris, and BeOS.
I have been involved in computers since the early 80s.While at the Mathematics Department at IVIC I acted as the de facto Network and System Administrator. Later on I was named coordinator of the Network Advisory Committee of IVIC, managing and securing a network of over 600 computers. At Patilla.com I acted as System Administrator of a small office network (6 to 8 computers, including a Windows 2000 Server).

Programs

I have real world experience with TeX, Wolfram Research Mathematica, Microsoft Office, Microsoft SQL, Macromedia Dreamweaver, Macromedia Fireworks, Adobe Photoshop, among others.

Internet

Basic web page design (HTML), administration of web, mail, ftp servers, basic database management. At Patilla.com I acted as Webmaster of the e-commerce site. I also managed the design, programing and development of the site. I became very interested in usability problems. I trained, supervised, and provided technical support for our customers. I was in charge of internet security and made all the technical decisions. I currently work in a bank that will open soon and publish a monthly security and IT newsletter in spanish.

 

Project Management

I have taken courses and work towards learning Project Management techniques. I have been the Project leader in several Projects involving Web and internet technologies. I am training to become a Certified PMP.
