Karavel, a major actor in online tourism, has proceed to the entire remake of its information system. The project's stake is to set the system more agile and performant to absorb the society large expansion.

The applicative architecture study end with the decision to develop specificaly several applications for a total of 4000 man/day. The applications differentiation is the generalized use of a business process-driven approach - BPM - and service oriented architecture -SOA. This approach aim to increase the flexibility of the provided applications and allow the offshore software development (spain).

As a technical architect, I defined the solution responding to the business, organizational and technical requirements. I notably realized :

Keywords : UML with PowerAMC 11. BPM/Workflow and EAI with Weblogic Server and Integration 8.1. Cluster Weblogic. Oracle 10g. J2EE. J2EE, EJB, Struts, Spring, Hibernate 3, Subversion, Maven.

The french culture minister has taken on the EVE project with the aim of remake several applications that manager cultural events in France. Pilot and innovative project, EVE implement the MDA - Model Driven Architecture - approach. This approach put the accent on system modelization and allow a high-level of abstraction aiming to bring productivity and quality benefit.

Within EVE, my technical architect role is centered around the activities of :

Gestitres is accompanied by Sopra Group within the context of his technological bend toward Java J2EE Technology. An asset allocation management for mutual funds selling project was initiated as the first project of this bend. It makes use of a multi-layer architecture with SOAP Web Services publishing and Mainframe integration. My intervention within the context of this technological bend and project was the following :

After this first experimental project that end up at a success, Gestitres decided to study the generalization and industrialization of the J2EE platform uses. I take the responsability of preparing the architecture's works : I identify and describe the tasks to be done, assess the charges and prepare a first planning.

Keywords : J2EE: EJB. SOAP Web Services with IBM Websphere 5.1. Persistence with Hibernate. Oracle 9i. Framework and Design Patterns implementation. Unit and functional testing with Cactus. Ant/Maven. Continuous Integration with Cruise Control. Training.

CVOO offers Online Content Management and Production tools and incentive campaign online management tools (point account, product catalog and online order). In the context of these projects, I defined and implemented a J2EE multi-layer architecture and the functional and technical design.

My work on the software architecture enabled the company to improve quality, shorten the development time while ensuring easy maintenance. I also managed schedules, budgets and customer relationships. These projects bring me about managing a five person team and supervising contractors work.

In addition to the implementation phase, I took part in the upstream phase of these projects that involved pre-sales, product line definitions and request for proposal responses. I also took part in the downstream phase by defining and running the productions procedures along with our services providers.

Keywords : J2EE: EJB/JSP/Servlet (Jboss cluster, Weblogic and Resin). MVC avec Struts. XML/XSL. Oracle 8i. Ant/Maven. Design Patterns. Unit tests. Aspect-Oriented programming. Project and team management.

For the “world capital increase” web application, a system intended to manage clients companies capital increases, I designed and developed the reporting architecture with the J2EE integration of Business Object’s Web Intelligence reporting system. I also designed and developed an alternative Java based solution for the performance critical part of the reporting.

I created the technical architecture for building a risk analysis tool including DCOM and J2EE interconnection.

In parallel to development I enhanced the common J2EE framework (set of J2EE design patterns, unit testing usage, build and development environment).

Keywords : J2EE. EJB (Weblogic 5.1 and 6.1). JSP/Servlet. Rational Rose. Sybase. Design Patterns. Unit tests. Ant.

Member of the “Risk Management” team of the Concorde Java application project (70 people, a structurally complex trade, position and risk management system supporting the markets business of JP Morgan. This product is installed all over the world and used by more than 800 people). My work was to specify and develop new functionality, such as:

I also performed bug fixes and enhancements to different versions of the application, which gave me a very good insight and understanding of the overall architecture. Also I wrote and ran several short courses to train my team on component design and compiler techniques.

Keywords : Java JDK 1.2 and 1.3. Swing + specific framework. Sybase. Sun Solaris. 3-Tiers architecture. XML. Clearclase.

Research on component methodology and development for my master's thesis (see “education” below for details): to complete this work, I investigated the latest component technologies (EJB, CORBA) and methodologies and applied my ideas to a prototype for a billing system, using EJB and CORBA with Java.

All of this work gave me a in-depth knowledge of component-based development. My Master's thesis placed first at the University Panthéon-Sorbonne.

Keywords : Catalysis method. UML. EJB: Jonas. CORBA (Orbacus). Swing. PostgreSQL 7.0.

My work was to specify and develop a Java CORBA component for a DataMining application. This component's role was to supply aggregate data to a set of neural networks and to manage data persistence.

Keywords : DataMining. CORBA (Visibroker 3). Java (JDK 1.1). JDBC. Oracle 7.

First, I had to analyse and model the Information System of the company using UML and Rational Rose. Secondly, in the development team for a nuclear power station inventory control managing system, my work was to do business development on GUI and application server part (we developed the application server from scratch). I also produced a user query engine linked to the Versant ODBMS. Finally, I made a document generation and printing component.
