Developer

4/2007 – 10/2007

Employed to design, implement, document and test processes for a WiFi
communication system that is a union of several client/server modules in a
communication chain and involves the provider, the user, a central unit, the DB, etc.
Invented, designed and implemented a smart idea to transform all the huge and
unreadable communication C state machines into simple and user-friendly dedicated
functions: a solution based on a matrix of C pointers to libraries and condition maps
to move within the states.

6/2003 – 3/2007

Contracted to modify, add-modules-to and make-Linux-compatible, a C++ bank
cheque and signatures reader program. Contracted also to design, create or modify
several C++ processes/programs/libraries making them Linux compatible and
adding " circularity " capability to most of them (documents viewable from all the
bank´s branches) by Tuxedo modules.
Contracted also to design and develop (full life-cycle) Pro*C++ and PL/SQL
programs for DB management; new DB tables, triggers and stored/time functions
have been designed and created when needed.

Oracle Database, UNIX, Linux (Kernel), Bash (Shell), C, C++, PL/SQL, Public Relations, Design (allg.)

9/2002 – 5/2003

Contracted to design and develop mobile-fraud handling software. C++ full life-cycle
programs, shell and PL/SQL scripts, designed and created to retrieve db data, create
HTML reports, send retrieve information by ftp shell script (Unix <=> Windows) ...
Modified a DWH Pro*C++ statistic program with speed enhancements - Oracle hints
and C++ tricks – and adding an auto-expanding memory to it, as a "fetched record
history". Invented, designed and created a smart way to avoid the Oracle
"rollback segment error" when fetching big Vodafone DB tables with Pro*C++
programs, using parallel C++ process implementation.

2/2002 – 7/2002

Analysis and development of the C and Pro*C programs and PL/SQL scripts for DB
data handling. Conception and creation of the working ambient: directories, environment variables, makefiles, creating/populating scripts, etc. Monitoring process (shell script) creation. Unix HP and C/Pro*C language teaching and supporting towards internal members.

10/2001 – 1/2002

Mobile data handling, PL/SQL scripts' conception, creation and optimization.
Analysis and development of the programs to interface Oracle.
Designed and implemented concurrent and parallel C++ processes to fetch large 's DB
tables "asap". Windows NT clients created using Borland C++ Builder 5.0 and
Visual Basic.

3/2001 – 9/2001

Responsible for all the Unix/Oracle project's part, full life-cycle: working ambient
conception and creation, C/Pro*C client/server designing and building,
environment/db creating scripts, stored procedures, triggers and time functions
creating scripts, testing scripts.

4/2000 – 2/2001

Initially programmer for a porting of all the C/Embedded SQL code and the database,
from Tandem OS/DB to a Unix/Oracle client/server system. Later
analyst-programmer to optimize the C client code and the DB queries.
Then, still analyst-programmer, modified and installed a Borland C++ client application for non computer-oriented staff to handle the phone cards data/events.
