Project:

Design and development of the back-end for an energy optimization system based

on AI for an industrial site Schneider Electric. The system collects real-time field data

and exposes it to the AI module and the user interface via a robust back-end layer.

⎯ C++ development of the back-end: design of data collection and exposure modules,

implementation of functionalities, unit and integration tests, bug fixing

⎯ PostgreSQL database design and administration: table modeling,

integration of TimescaleDB for time series, development of PL/pgSQL functions

with triggers, implementation of asynchronous notification systems

⎯ Administration of a hybrid Linux Debian 11 environment: orchestration of native processes and

Docker containers for service deployment

⎯ Writing Python scripts for test automation, data validation, and development tooling

⎯ Code quality assurance via Coverity (static analysis) and SonarQube (quality metrics); dependency management and compilation with Conan

⎯ Project management using Agile (SAFE) methodology via Azure DevOps, Jira, and GitHub (code reviews, pull requests, sprint management)

Environment:

Linux Debian 11, Docker, C++, Python, PostgreSQL, TimescaleDB, Conan, Coverity, Azure DevOps, Jira, GitHub

- Definition of the device error management architecture

- Development in C++/QT under embedded Linux (Yocto)

- Development of a QT/QML/C++ application for a test bench

- Code testing on the device or simulator

- Development of Python scripts for parsing Excel documents or analyzing data

- Analysis of bugs reported by users

- Code review for firmware and software

- Use of SVN, GIT, and Jenkins

- Performing unit and functional tests

- Writing documentation and specifications

- Use of Agile methodology on the project

- Working in a team of about fifteen people from various disciplines.

Role: Embedded Systems Engineer

Technical Environment: Windows, Linux, C Language, E2Studio, VSCode, Makefile JIRA, git, Confluence, GitLab

Languages Used: C, Python, Bash and UML (QM) RTOS: FreeRTOS, QP Framework

Summary: Participation in the development of a tracker for vehicles (cars and two-wheelers)

Project:

- Maintenance (improvement and bug fixing) of the current version (QP Framework and RX100)

- Migration of the product source code following the microcontroller change (Renesas RX100 to Renesas RA2L1) and update of the QP Framework. Development of the low-level layer and readaptation and improvement of the application.

- Development of a new version of the tracker (development on STM32L4 with FreeRTOS RTOS)

- Definition and implementation of the application architecture, project tree, and compilation tools.

- Development of low-level layers (Drivers and libraries) and the application part.

- Implementation of unit and functional tests

- Code optimization and use of microcontroller mechanisms to reduce consumption as much as possible.

- Use of computer-programmable power measurement tools (NI DMM).

- Implementation of SigFox and LoRaWan communications using Semtech's sx1272 and lr1110 modems

- Use of classic GPS and "GNSS RAW DATA"

- Implementation of communication via LTEM.
