Librezo gives you back control of your data:

• Take them out of private data smugglers thanks to open source solutions.
• Get them out of datacenters thanks to our self-hosting solutions.
• Secure them like never before thanks to our OpenPGP solutions.

Managing GauSSIan GNU/Linux Operating System and its ecosystem:

• Build and maintain hundreds of packages.
• Design and implement an Internet-Of-Things Proof-Of-Concept (thingworx).
• Invent and maintain a simplified build system, producing ISOs and packages (repobuild).
• Administrate dozens of services and improve coherence with their hosts.
• Set up tools to automate tasks.
• Set up and maintain a Public Key Infrastructure.
• Invent and maintain a lightweight solution to manage thousands of system configurations.

Designing and implementing protocols and Proof-Of-Concept. Some ideas behind this project were taken up in Cesium to build a libre currency. Alas, not all of them. Especially those of using and extending OpenPGP to:

• Deploy strong and non centralized authentication over Internet (Extending HTTP protocol).
• Establish cryptocurrencies where monetary creation is achieved from the existence of authenticated individuals.

Embedded Linux and Set-Top Boxes Expert:

• Identify, prevent and resolve issues concerning millions of deployed devices.
• Advise R&D and projects Leaders.
• Review feature requests, technical and functional studies, technical implementations.
• Build customized Set-Top Boxes for specific tests or Proof-Of-Concept.

Designing and building software architectures and applications around embedded web browsers, mainly webkit-based, on ST7109 then BCMxxx chipsets:

• Benchmark, study and fix issues with JavaScript engines, chipset drivers or infrared control.
• Redesign the API of a JavaScript middleware.
• Build and support dozens of prototypes for our various European partners.
• Invent a browser-independant middleware, using binary cgi-scripts.
• Demonstrate how to use this middleware to browse and play YouTube, DailyMotion and AlloCine content on Set-Top Boxes.
• Build a complete HTML/CSS/JavaScript Proof-Of-Concept of a music application, in partnership with Deezer. For Pace’s stand at the IBC 2009 (Amsterdam).

I was hired for my GNU/Linux skills to help their project of a Linux based mobile phone. Unfortunately this project has been abandoned 2 months after my arrival. I didn’t understand this decision and I hope the ones who did now regret, since the tremendous success of (Linux based) Android smartphones. As I had still many things to learn in this company, I moved then in their retrofit and secure boot teams.

• Choose and customize a GNU/Linux Distribution (Mandriva) for Sagem’s developer’s need.
• Set up tools and procedure for workstation installation: dual boot, with each OS able to run in a Virtual Machine hosted by the other.
• Contribute to the Linux Bluetooth stack BlueZ, and integrate it on the Sagem Embedded Linux OS.
• Retrofit and secure boot: developer on C code with high constraints: criticality, security, ascendant compatibility.
• Retrofit and secure boot: support and expertise for other R&D teams.

3-month mission to finish a LabWindows/CVI tool to manage and update software configurations on heterogeneous Windows machines (NT, 98, XP).

Updating training materials and training professionals, about shells or C/C++ programming, or configuring network and services (Apache, bind, MySQL, samba, ssh, NFS, ftp, rsync, etc.). At that time, I had almost no idea about customer’s professional lives, so I couldn’t meet their expectations, and this 4-month experience was a failure.

Designing and building a multimedia domestic server (Set-Top Box concept) using Open Source software:

• Choose software and hardware platforms for prototypes (Gentoo Linux and Asus Digimatrix).
• Configure and customize software components: drivers (Lirc, Tuner TV), front-end (MythTV), etc.
• Market analysis, partnership and funding research.

Open Source solutions of video streaming for military remote operation. Constraints: rate, quality, latency.

• Benchmarks, profile, test and functional analysis of existing solutions.
• Customize the chosen one (MPEG4I): C/C++ Development, Tests, Validation.

Study standards ISO 7816-x, then develop a ANSI C library and a Borland C++ GUI to manage smart cards like PayFlex or Visa.
