About Joëlle

I have concrete expertise in software testing:
- Unit and functional tests on Back and Front-End using Jest, Flutter test, Dart test,
- MBT development, scenario writing, and test automation.
I developed these skills at olome, a company that develops industrial management software.

I also know how to develop software:
- Requirements elicitation
- TDD development, unit tests with unittest
- Python development with the use of libraries for geographic information systems (GIS) pyshape and rasterio.
- Interface testing with Robot Framework.
This was achieved through the development of software for FORESTY (a consulting firm for foresters).

I am familiar with Web development, using PHP with SQL database queries and creating a suitable graphical module.
I learned this while developing a web page for VigieNature Ecole (part of the National Museum of Natural History in Paris).

My initial mathematics education taught me to work rigorously and in a structured manner, and it enables me to understand certain mathematical aspects of requirements (especially for GIS).

My years of teaching have given me skills in adaptation, teamwork, and pedagogy.
After a career change, I hold a Master's degree in Software Development and Validation from the University of Bourgogne Franche-Comté.

I am also ISTQB certified at the foundation level.
