- Origalys Electrochem SASDevelopment of software for controlling measurement instrumentsRESEARCHApril 2024 - Today (2 years and 2 months)Rillieux-la-Pape, FranceProject Context and Objectives:Design and development of a complete software solution for controlling electrochemical measurement instruments such as potentiostats/galvanostats. This project aims to provide researchers and industry professionals with a tool for conducting electrochemical experiments, acquiring real-time data, and performing analysis.Technical Architecture:- Core functionality in C++ ensuring communication, real-time data acquisition, and critical scientific calculations.- Modern Web User Interface (HTML/CSS/Javascript)- Web server in Python/Flask serving as an intermediate layer between the user interface and the C++ DLL.
- Origalys Electrochem SASAudit of memory leaks and implementation of fixes in legacy C++ applicationsSOFTWARE PUBLISHINGMay 2025 - July 2025 (2 months)Rillieux-la-Pape, FranceContext and Objectives:Identifying slowdowns and random crashes in two legacy C++ MFC software applications. This mission includes the use of specialized tools to precisely identify memory leaks, and the implementation of sustainable fixes to restore performance and stability, while minimizing impact on existing code.Tools Used:PVS-Studio -> Static code analysis for highlighting potential leaks.Dr Memory -> Dynamic analysis of running applications to detect memory leaks.
- Origalys Electrochem SASAutomation of functional tests for measurement instrumentsSOFTWARE PUBLISHINGJanuary 2024 - March 2024 (2 months)Rillieux-la-Pape, FranceImplementation of an automated functional test suite to validate the behavior of electrochemical measurement instruments (potentiostats/galvanostats).Before this mission, validation relied entirely on a manual process: an operator connected cables, ran measurements, and visually compared results with expected values — a long, time-consuming, and error-prone process.Result: 85% reduction in validation time, from ~2 hours to ~20 minutes per test day, with reproducible coverage and no manual intervention.
