SOF and Zephyr developer. SOF maintainer for bash, Python and others. Co-maintainer of Zephyr's west meta-tool.Migrated the SOF logging system and SOF build system to Zephyr.Led the effort that fixed validation and achieved Continuous Integration for SOF. Relentlessly triaged, debugged, analyzed and fixed countless false positives and false negatives across the product stack: in sof-test code, automation, build systems, Linux driver, Zephyr and SOF code. Added static analysis and linters and transformed the automation and development processes into a reliable and trusted workflow that catches most regressions immediately and boosts development velocity.Worked with Fedora and Ubuntu audio maintainers to refactor the sof-bin release process for Linux distributions.

Feasibility explorations based on open-source firmware. Fixed and upstreamed reproducibility issues in the Zephyr build system (later automated in SOF).

Backported about 1500 Linux drivers commits to stable git branches used in Google's Chromebooks product line. Debugged kernel issues and reported them upstream.Trained and led a small team of engineers that scaled this process and provided the main technical point of contact for Google's team.

Trained, led and mentored the team of Linux engineers that implemented and delivered the first public releases of Yocto/Linux software support for Quark, up to the v1.0, first "gold" release.Designed and co-implemented the internal, continuous integration of the Intel X1000 Quark SDK, including UEFI firmware and secure boot.Provided 3rd level support to Intel X100 Quark internal and external customers.Designed and partly implemented the internal, continuous integration of the Quark software build, including UEFI firmware and secure boot.Technical relationship with first rank Quark customers and partners inside and outside Intel, including 3rd level support.

Made diversifEye's, core client-server networking technology robust against network failures and compatible with firewalls and NATs. Reversed-engineering, fixed and enhanced diversifEye usage of Java RMI.Main developer of the network monitoring product servicEye spider: implemented about 80% of the software not coming from previous Shenick products.Implemented in C the DNS client and test server of the real-time, light-weight, DPDK-like TCP/IP stack which powers the core of diversifEye and other, Shenick products. Ported that TCP/IP stack to Linux 64 bits (CentOS).

Removed the Java-based serialization part of the Sequoia JDBC driver, replaced by a binary protocol designed for C++ compatibility. Co-author of the Carob C++ client library. Ported carob and libmysequoia to FreeBSD and MacOS X. Wrote the ODBSequoia ODBC driver.Significant contributions to the build & QA framework. Shell and Ant scripting, JUnit. Automated the system administration of a cluster of 60 Linux hosts.

Research on congestion, flow control and performance in TCP/IP/Ethernet networks, involving Linux kernel programming. Implemented the Solaris kernel driver of the "Clint" FPGA prototype network interface.http://marc.herbert.free.fr/noq/https://labs.oracle.com/pls/apex/f?p=labs:40150:0::::P40000_PUBLICATION_ID:1793

Developement of CADP, a model-checking toolbox. C programming in Solaris, Linux environments. Porting to Windows with MinGW (Solaris to Windows cross-compilation).
