(Paris,
France)
Pixium vision Freelance software architect
Project : Vision Restoration System through retinal implants.
A camera sends an image to a pocket PC running linux on an ARM
processor. A DSP processes the images and formats them before sending
laser pulses that stimulate the implants and generate electrical impluses
on the optical nerve.
Tasks :Design, implementation and documentation of a multi task,
multi-processors software architecture.
This architecture controls, transfers and formats camera data. These
data are used by a µMirror array to focus a laser beam onto an implant. It
also guarantees the safety of the implanted patients.
Implementation of system tasks, interfaces and tests using a message
and shared memory IPC.
Linux driver and interfaces for PCIe, DMA, SPI, UART, I2C and SD cards.
Impement the boot loaders for the various HW platform
Web interface written in CGI to control and test the system.
Trained the SW engineers in the team.
Interfaces with the engineers involved in the project (HW, optical, etc.)
Achievement : Created the project’s architecture , implemented a
viable system and delivered it for the first integration milestone.

HORIBA JOBIN-YVON R&D electronics contractor
Projects : Infra red spectrometre for medical devices.
Automated board for SPR imaging devices: Motor drivers, temperature
control, etc.
Automated board used on several devicesfor multi-instruments
(glowing device and mass spectrometer)
Tasks :Designed the architecture, captured the schematics and routed
the PCBs (Up to 6 layers, mixed signals and Fine Ball Grid Array
technology).
Coded the firmware in VHDL and C for the ARM and FPGA on the
boards.
Created a test bench and coded the softwares in C and Delphi.
Designed life time test scripts.
Interface with suppliers and other engineers involved in the projects.
Took other the DLL interfaces for USB and Ethernet.
Achievement :Designed a better and more versatile electronic than
the competitors in a relatively short amount of time.
Debugged the firmware issues that were stalling the project.
Reverse engineered and debugged old code.

ELTYS KHI3 Project Manager
Project : Web-based Reporting tool, for analysing SQLs data.
Tasks : Designed, coded, tested and deployed the application.
Architecture of a Graphical user Interface for web pages.
Data mining of SQL cubes via complex MDX requests and conversion of
the data into several formats: HTML tables and Open XML that could be
reloaded and saved on the server or on the user’s computer.
Achievements :Creation of a web application with SQL processing.

Sequans Communications Freelance integration Engineer
Project : ASIC design for mobile phones using LTE and Wimax
Tasks : Creation of tests harnesses, integration and validation of LTE
and WiMax chips.
Coordinated several teams to solve the bugs (DSP, ASIC, etc. )
Analysed and developed the MATLAB models for the LTE transmission
chain.
Achievements : Interfaced with Motorola to setup the first uplink tests
against an eNodeB

(Toulouse,
France)
Freescale Ltd Freelance DSP Engineer
Project : Design of HW accelerators for the GSM mobile phones.
Tasks : Design, simulation, integration and tests of new algorithms.
Performance evaluation of a GSM Hardware accelerator for all the traffic
and signalling channels.
Achievements : Redesigned and coded parts of the EDGE equalizer
(channel estimate, and time of advance). This algorithm improved the
performances of all 8PSK sensitivity tests (14.18.1). One test case was
failing with 10.14 % of BER and passed with 6.61 % of BER.
Produced performance evaluation documents that led to the correction
of design flaws. Contributed to the design and coding of an algorithm
that removed spurs generated by the radio.
