Project History
Dec 1998 Mar 1999
Software developer consultant
FICS, Brussels (Belgium)
I worked as C++ Developer for a financial Windows application using the Borland 4.52 compiler. I implemented 4 DLLs related to new specifications in the product. The DLLs were called from a Visual Basic application and they generated messages after reading the appropriate data in a database. These messages used the SWIFT inter-banking tag protocol system wrapped with EDIFACT headers and trailers. The development was done using object oriented techniques. It used the open database connectivity (ODBC) libraries for Windows.
Mar 1997 Nov 1998
Analyst/programmer consultant
Belgacom, Brussels (Belgium)
I worked for the Customer Oriented Billing System project. I developed part of a police investigation application consisting on the server side of a system for searching telephone numbers. The application received messages containing telephone numbers to be scanned. These were stored in a database. My program searched for those numbers in the telephone calls data files, retrieving the results back to the client.
I wrote a general ledger aggregator application that added the amounts coming from the billing system according to the criteria defined in the bill, producing reports for accounting. These applications required high performance due to the volume of data to be treated and the response time to be given. I did the development in C++ under Unix (NCR and HP machines). I worked with the Rogue Wave Tools.h++ library, PRO-C/C++ and PL/SQL for accessing Oracle and Top-End as middleware for inter-process communication.
Jun 1995 Nov 1996
Software specialist consultant
INSA, Madrid (Spain)
I worked within the Off-Line Processing and Product Archive Group at ESA (European Space Agency) satellite tracking station of Villafranca del Castillo for the Infrared Space Observatory. My main task was the operation of the off-line processing system. During the development and test phases, I wrote operational procedures and developed some software in C and some UNIX and VMS scripts for data processing automation. I worked with astronomical databases under SYBASE.
Jan 1994 Dec 1994
Ph.D. Student
Cadiz University, (Spain)
I followed Ph.D. courses in the physics department of the University of Cadiz. My main subjects where material properties. I worked with X-Ray diffraction equipment and software packages for material structure determination in amorphous silicon. I also took a course in satellite technology applications using GPS. I started to use a new generation of internet applications.

Trainee
ESA, ESTEC, Noordwijk (The Netherlands)
I was granted a scholarship to go to the European Space Agency Technology Center (ESTEC). I worked within the mathematics and software analysis section (WMA), which was involved in modelling the space environment.
I wrote around 10 reports presenting results of analysis in different orbits and for different satellites for space debris impacts, radiation doses and atmospheric tables. The analyses were done with ESABASE after introducing a spacecraft model.
I wrote my MSc thesis on the number of impacts on a satellite and one Working Paper containing tables of the expecting radiation doses in different conditions in Low Earth Orbit.
I did programming in FORTRAN to test new software and I learned about the ESA software engineering standards.
