• High School Diploma in 1978.
• Two-year intensive program preparing for the national competitive exam for entry to engineering schools.
• Top French engineer school : École Centrale de Paris (Diploma in 1984).

"Le meilleur développeur de France" is a programming challenge,
that took place in the 42 school founded by Xavier Niel

CodinGame Contests are online programming competitions,
where software developers / programmers from all over the world
can compete.

When constructing a building, what is most important to you?
Foundations will you answer me ... and you're right!

YAK Pro – Web Portal System, if we keep the analogy, is the foundation, but also
all the hard work, bearing walls, piping and wiring, everything that makes the result well designed and functional.
You just have to take care of the decoration and of the furniture ...

The software supports the whole content management and infrastructure part of your site.
A graphic designer and a Webmaster are enough to manage and maintain your professional website!
This allows you to save a whole team of developers.

Analysis, design and implementation A to Z of an inventory management software.
(Groupware, CRM, Quotes, Orders, Processing, Audits, Billing, Accounting, Customer Portal,
Internet base real time team management, codebar scanning software, etc.)
Each module was created as follows:

• Understanding the existing company process model, its data flow, interactions.
• Propose solutions to optimize the business processes.
• Validation with the company manager.
• Functional specifications, coding, testing, validation.
• Deployement.

A compiler translates a program source code in a binary form which can be directly be executed by the target processor.(e.g., C ).

An interpreter, as its name suggests, interprets the source code at run time. (e.g., Basic).
It can also compile the source code into an intermediate processor independant code named P-code,
that will be interpreted at the run time (e.g., Java).

A meta-compiler helps to conceptualize and modelize a programming language
using another language that is called a grammar.

It generates the lexical analysis, the syntaxical parsing, and the semantic analysis part of a compiler from the grammar.

A programming language needs also:

• a runtime environnement.
• a standard library that interfaces with the operating system.

It was a multiple challenge:

• both prove to the management that the team skill level was much further than bug correcting,
• and also allow porting external programs on our system..

The Basic 8000 interpreter compensates the too modest performance of the virtual machine.
It make possible the succes of the IN8000 machine.
It also enables the sale of IN2 to Siemens.

This Rapid Action Force, consisting of the most responsive and competent developers,
had been introduced for the release of the new range of machines, to act quickly to large account customers,
in order to diagnose the cause of complex problems and coordinate the work of teams.

In a joint project with an American company based in Boston,
I was sent 1 month in the United States to interface and negotiate
features between american and french teams.

After the acquisition of IN2 by Siemens
I regularly performed trips to Germany and worked with German teams on projects.

Be exhaustive over 30 years of software development is not such an easy thing.

On this site you will find a list of the most representative projects of
the skill mix I was able to develop during my career.

A huge variety of projects helped me to familiarize myself and to master many
areas, concepts, languages and tools.

That enables me to have an overall view of the problems encountered in software development.

My ability to apprehend new environments, new languages, new areas
were the reasons that led my line managers to choose me for innovative projects requiring the acquisition of new knowledge.

What do you think of this system?
Would there be a smarter way to organize my database,
to optimize development time and/or response time?

Wondering questions, facing a technology, architecture, design,
model, infrastructure, or tool choice is a common thing for developers.
It is crucial to avoid making mistakes , as it engages the future of a project.

Once the project committed and the development started, other questions arise:

• I have a bug, I do not understand why?
• How to implement this feature without compromising anything that has already been done?
