Technisys
From 1996 to 2003
- Bansud Direct
- Development of home banking on both the server side and the
front-end side.
- Pagomiscuentas
- Design and implementation of a cryptographic security scheme
with digital signature (public/private key) to allow
the transference of logged users from many sites to PMC
site (single sign-on). It was made in C language using the OpenSSL
library and PKCS standards.
- InfoTrade
- Adaptation of the "Pago mis cuentas" ("Pay my bills") system. At that
time it was necessary to create an interface with Java (using JNI), PHP
(creating a C module so that these functions looked native from PHP) and
with Windows (creating a DLL and invoking it from VBScript/ASP).
- ABN AMRO, Bansud, Deutsche Bank
- Participation in the development of the C broker technology which was
the backend of these home-bankings. This backend used an RPC based technology
to communicate with the clients.
- Bansud
- Participation in the development of a suppliers management system for
Bansud programmed in Oracle's Pro*C/C++.
- Interbanking
- Participation in the development of the Interpyme system for
Interbanking. For that project: design and implementation of a
OO abstraction layer over a relational database (a custom Object-Relational mapper). Adaptation of
the JSP server software used so that it could use M4 preprocessing.
Creation of a high performance connection pool, oriented to
the massive concurrent use.
- Citibank
- Development and maintenance of the salesmen and client-support web
application. Design and implementation of
the insurance portal using Cocoon 1.x. For
that project, development of modifications in Cocoon Apache software (that were
included in the official version). Development from scratch of an
implementation of the TLS protocol (SSL 3.1) in Java. Creation of a
system that automates the RPC using XML-RPC technology. This software,
based on a definition document, generates code that allows a C application
to interact transparently with Java, Perl, PHP, etc. applications
by sending XML-RPC messages.
- Stock market
- Development of the original version in Swing of the "Active Feed"
applet, for displaying stock-market values (Bolsar Vivo). Later
re-engineering of most of its structure. This applet takes care of showing
the prices of the papers online.

using JavaMail and JSP technologies. It supports file attachments and
reception of MIME types, text type text/plain;format=flowed, contact-list, etc.

- Installation, maintenance and problem investigations related
to the application "Visa@Home" (Java over Sun equipment). I developed
a system of backup in tapes in Sun platform.
