Work Experience

[Feb.2006 - June.2007] Engineering Manager, Core Labs. Mandriva, Paris, France.
Head of Mandriva Core Labs which consists in Core Engineering, HW Quality Assurance and HW Enabling. In direct relation with key hardware vendors: AMD, Intel, ATI, nVidia. Still in charge of Mandriva Linux 64-bit ports and the compilation toolchain.

[Jan.2004 - Jan.2006] Team Leader, Core Engineering. Mandriva, Paris, France.
Manage the Core Team, a small group of 5 people in charge of low-level projects at Mandriva: Linux kernel, compilation toolchain, ports to other architectures, Linux Standard Base, localization and internationalization.

[Jul.2001 - June.2007] Software Engineer, Core Engineering. Mandriva, Paris, France.
Maintain the compilation toolchain, namely GNU Binutils, GNU Compiler Collection, GNU C Library.
Lead developer and architect of 64-bit Mandriva Linux distributions (ia64, ppc64, x86_64).
- Adapt installer to the new architecture needs and create ISOs.
- Review and fix packages generally from compile logs and code inspection, covering 64-bit, multiarch, ISO C & C++ compliance.
- Contribute to porting small to larger scale applications like the Kaffe JVM, Dietlibc, Mozilla, OpenOffice.org.
- Developed Mandriva Linux multiarch support for 32-bit run-time and development on x86-64 platforms.
- Developed one of the first complete 64-bit Linux distributions available to the x86 architecture.
- Gave talks about software porting to 64-bit architectures at the AMD Developer Symposium 2002 (Frankfurt, Germany) and Linux Solutions 2003 (Paris, France).

[Jul.2000 - Aug.2000] Intern. IRISA, Rennes, France.
Worked within the Compiler and Architecture for Superscalar and embedded Processors (CAPS) group at IRISA, a public funded Research Institute. Developed a retargetable graph coloring register allocator in C++ with the LEDA graph library. In addition to that, the implementation was modular for easy integration and testing of various spilling heuristics (e.g. Chaitin, Briggs).

[Oct.1999 - May.2000] University project. INSA, Rennes, France.
Co-developed COCA, a debugger for C based on fine grained control flow and data events. COCA uses a query language built on top of Prolog and instruments C code. Also worked on an extension for memory bounds checking and studied the upcoming ISO C 9899:1999 standard and its implications for support into COCA.

Personal Projects

[2005 - Present] nspluginwrapper.
Author of nspluginwrapper, a proxy plugin and a viewer for Netscape 4 compatible plugins. It makes it possible to use 32-bit x86 plugins like Macromedia Flash Player and Adobe Acrobat Reader with x86-64 compiled Mozilla browsers. Gained experience in Netscape Plugin API.

[2003 - Present] SheepShaver.
Contribute to SheepShaver, an Open Source PowerMacintosh emulator. Author of the first PowerPC G4 CPU emulator with just-in-time translation. Also gained experience in X11 clipboard management for exchanging text between MacOS and the host OS.

[1999 - Present] Basilisk II.
Contribute to Basilisk II, an Open Source Macintosh 68k emulator. Merged and improved a high-performance just-in-time translator with lazy translation cache invalidation for a near 80% speed improvement. Ported the JIT to x86-64. Also improved video screen refreshes by a factor of 2.
