Entreprises

  • ENovance - System engineer & LDAP expert

    2009 - 2009 • Project quality & industrialization:
    Introduced methods and tools to attain controlled quality levels on internal development projects. This included extensive use of continuous integration, version control best practices and some methods of 'agile' development.

    Industrialization was improved with pre-configurable software packaging for fully automated installs (for Debian systems, via debconf and LDAP).

    • LDAP & Identity Management:
    For customers and internal projects, I studied identity availability requirements, and designed LDAP directory specifications (DIT, ACL and schemas), proofed using OpenLDAP.

    Projects included a strong focus on integration, including synchronization with existing repositories (databases, directories and flat files) and transparent SSO using Kerberos.

  • Normation - CTO / Owner

    Paris 2009 - maintenant In 2009, I co-created Normation.

    Normation is a software company based in Paris developing software to run and manage IT infrastructures, and providing expertise in the configuration and identity management fields.

    2006 - 2006 I designed and implemented a communication protocol with high availability and failover as priorities. Using the C language, I programmed it for a multi-threaded environment, sending and handling various system signals and multiple network sockets. All work was done in a Linux development environment (glibc, gcc, autotools, Makefiles …)

  • PraKsys - Automating server configuration with LDAP directories

    2006 - 2006 Designed specifications to automate and centralize configuration of multiple network services on Debian Linux, particularly well-known open source servers. This included an advanced self-generating web administration interface for LDAP directories (LLAZY), integrating software configuration in OpenLDAP schemas and system scripting in Python and Bash.
