 July 2020 – Ongoing ½ Tunis, Tunisia
- Project: FOTA Step2 (Client: Renault Nissan Alliance)
Context: Integration & Validation of FOTA Step2 features
• Adding the support of flashing single/customized image by recovery stick.
• Adding the boot on recovery mode with a special screen instead of booting
on fastboot when all slots are unbootable.
• Patch review.
• Bug Analysis/fixing of some FOTA Step2 features: Recovery mode, FOTA
IHM, FOTA security check...
• Writing Test use cases for new features basing on requirements.
• Part validation of different modules of A-IVI2 (USB Update Manager, FOTA,
Recovery mode...)
• Sanity check tests of each release delivered by LGE: recovery update, IVI
full update from n to n, IVI fake delta update from n to n+1...
• TOOLS : Embedded Android, C/C++, Git, Confluence, Jira, CANoE ...

Oct 2019 – Juin 2020 ½ Tunis, Tunisia
- Project: SWEET200 ADAS ECU (Client: Renault Nissan Alliance)
Context: Integration/porterage of Matlab/Simulink ADAS modules to be implemented in AUTOSAR architecture
• Comprehension and in-depth documentation of different modules of ADAS
ECU.
• Isolation of different modules of the project to set up a unit functional test
environment. Input/Output data have .mat and .csv format.
• Test isolated module in SCALEXIO with frame send/receive via CAN and via
Ethernet (UDP and TCP).
• Implementation of Sfunction, with matlab script, that links to a static library
(QNX format) and test the generated Simulink model in Dspace.
• Implementation of C++ Server/Client which ensures communication between SCALEXIO and a process in a seperated computer that uses shared
memories.
• Contribution to the development of a Central Database that gather and
unify all information shared between SWCs.
Its integration in CI/CD workflow (Git submodule, filters, Job creation...).
• TOOLS : Matlab scripts, Simulink models, C++, Shell, ATLAS, SCALEXIO,
Git, Confluence, Jira, CI/CD ...

Oct 2018 – Sept 2019 ½ Tunis, Tunisia
- Project: VCM HIGH (Client: Volvo...)
Context: Development/Bug fixing of Telematics features in the automotive
field
• Implementation of a DID (Diagnostic IDentifier) that helps reducing SIM
switch (internal SIM/external SIM) test duration to be compliant to client
requirement.
The idea is to pre-test this feature and save the result in RAM during a predefined configurable time.
• Implementation of a DID that checks the state of health of the BuB (Backup-Battery) of the board. It sets/resets BUB mounted date and BuB lifetime
in persistent memory after battery change.
A DTC (Diagnostic Trouble Code) will be set if BuB lifespan counter reaches
BuB lifetime value.
• Environment setup for worst case analysis tests in order to test Telematic
CPU performance (CPU load, memory usage).
• Code analysis and optimization in order to reduce memory usage.
• Bug fixing in diverse modules such as power management, audio, buttons
and LED:s diagnostics, IMX control ...
TOOLS : C, IAR Embedded Workbench, IAR Visual State, DSA, Tera Term,
Cygwin, Klocwork, SVN, Jira, DOORS, CANoE, IHU client simulator,
ACC...
