Expérience professionnelle

Company eProseed Europe SA
Period June ‐ August 2011
Role
Brussels XML & SOA Expert
 European Commission – Directorate General Research & Innovation (abbreviated RTD): Florent conducted an audit of the Common Data Model, developed by a join working group between DIGIT, RTD and INFSO. The CDM is the central piece of the SOA initiatives in the several Research DGs at the European Commission, providing a standardized data model in XML Schema and a series of common Web services. The audit aimed at advising the working group on technical aspects (mainly XSD and WSDL) as well as potential SOA governance issues (like versioning, releases, discoverability, SOA goals & concepts, and documentation).

Company Organisation for Economic Co‐operation and Development
Period May 2011
Role XProc trainer
Paris  The Organisation for Economic Co‐operation and Development (also known as OECD, in French OCDE) is an international economic organization of 34 countries, based in Paris. A large part of their objectives is publishing documents and statistics. They naturally use more and more XML to represent their content, and wanted to start a first project using XProc to leverage its integration of several core XML technologies in order to represent their XML processing pipelines. Florent wrote and gave a training on XProc, from the very basis to setting up the architecture of the project.

Company EMC²
Period December 2010 – May 2011
Role XML & XQuery Expert
Paris
 Credit Agricole Group – CEDICAM: CEDICAM is the « Cards & Payments » entity of the Credit Agricole Group, and as such has to implement the new European Directives relative to financial transactions and payments in the SEPA zone. This represents a huge volume of heterogeneous data, received and stored in an EMC native XML database (also known as XDB), and accessed and modified using XQuery. Florent worked on the XQuery layer (principally designing the query generation, and the optimization of queries on large data streams).

Company John Wiley & Sons
Period 2010
Role XQuery & XSLT Expert
London
 Wiley is one of the largest publishing companies in science and academics.
Wiley Online Library is its subscription‐based, multidisciplinary digital library.
According to Wikipedia, « Wiley Online Library delivers integrated access to over 4 million articles from 1500 journals, 9000 books, and hundreds of reference works, laboratory protocols and database ». All the publications are stored in a MarkLogic native XML database. Florent worked on the XQuery and XSLT layers, in particular on the query optimization on large documents volumes and sizes.

Company European Commission – Directorate General Research & Innovation
Period April 2008 – December 2009
Role XML Expert & Application Architect
Brussels  Business Analyst and Architect: The Directorate General Research & Innovation (abbreviated RTD) is responsible for the founding of research in Europe. It has one of the largest budgets of the European Commission, and handles XXXX of new contracts a year, with Universities, Consortia, SMEs, and individuals. The processes involved are complex, and sometimes participants want to submit requests for redress.
The handling of such requests for redress used to be manual. This project was aimed at developing a new web application accessible to the participants (frontoffice application accessible from the outside world). Florent was the Business Analyst from the very beginning and the Java EE Architect. The technologies used were Java EE 5 on Oracle WebLogic, using Oracle database through Hibernate, with JSF for the front‐end and Spring for the bean container.
Integration with the participant portal was achieved through Web services.

 Project Manager and XSLT/XSL‐FO expert: The RTD has to evaluate all requests for founding through committees of experts (the domains of the proposals is broad and can be as complex as nuclear research). Those evaluations last from a few hours to several weeks or months; they can involve a few experts to hundreds of them. This project provided a distributed application to help the executives to manage the evaluations, the experts, the buildings and the rooms where they take place, and the facilities they provide. PDF plans and tables are generated through XSLT and XSL‐FO using a homemade SQL‐to‐XML bridge.

 Business Analyst and XSLT and XSL‐FO expert: A new application was created at RTD in order to allow participants to fill in several forms online. Florent analyzed the original forms with the business, helped the business to rationalize them and factorize them out, and wrote a set of XSLT stylesheets to generate them back in PDF.

 XML Expert: A new system was developed to handle the negotiations between RTD and participants in order to define the exact terms of the contracts. The system used Orbeon Server (providing XForms) for the front‐end, eXist for the database, XPL for the XML pipeline language, and used intensively XSLT and XQuery to access and transform data.

Company Acheron Capital
Period December 2007 – April 2008
Role Project Manager – Technical Leader
London
 Acheron Capital is an investment found company based in London. Due to a very fast growth, their IT was not able to cope with the changes in the company.
The project was to analyze, design and implement an entirely integrated custom back‐office, based on SOA principles in order to enable the IT to rapidly adapt to futures changes (at the time, other companies were being seen as potential acquisitions).

Company Atos Origin Belgium
Period March – November 2007
Role SOA Specialist
Brussels  Mobistar: The ability for a customer to look at his/her consumption in real time on the Mobistar portal was the opportunity for Mobistar to have a first shot at the SOA technologies and principles. While they had already a range of Web services, they were used principally as a mean of integration. Mobistar was interested in particular in the various WS‐* specs and the concept of an ESB to provide a standardized communication and integration facility accross the whole enterprise. Florent designed the contract of several independent Web services and implemented them using Java EE, and he took part in the design of the whole SOA solution and of the ESB implementation.

Company ING Lease Belgium
Period July 2005 – February 2007
Role XSLT and XSL‐FO Expert
Brussels  Result of several merges and acquisitions, ING Lease Belgium decided to build a new back‐office application for its employees. In order to leverage legacy systems, SOA was the natural approach. It was also the opportunity to rework all the documents (from quotes and invoices to contracts and reminder letters).
Florent analyzed those documents, coming from several different entities, in close relationship with the business, factorized them out, modeled them and implemented them, from generating an abstract XML representation out of the database, transforming it using XSLT to XSL‐FO, to finally generate PDFs.

Company European Organization for Nuclear Research
Period February – May 2005
Role Developer
Geneva
 The European Organization for Nuclear Research (also known as CERN) is the biggest nuclear physics research center. Its major tool is the LHC (a ring 27 km in circumference, composed of large magnets, the world’s largest and highestenergy particle accelerator). The AT/MTM group (Accelerator Technology
Department / Magnet Tests & Measurements) was responsible to test every single magnet built to compose the LHC. The group used a homemade application to present digits (stored in a large relational database) to pysicists and let them make some computations.
The application was build using OOC (Object‐Oriented C), a homemade layer on top of standard ISO C to provide the developer with object‐oriented facilities.
The role of Florent was to design the data‐access library for OOC (a JDBC‐like library), and to implement it for Oracle (using OCI).
