Outcome
Still in production eight years later, extended by the INRAE team; cited in 2 articles and 2 theses

Starting point

INRAE researchers modelled fruit metabolism with a single-file MATLAB program. Its single licence limited it to one user at a time, on one dedicated machine.

The delivery

EasyReg, an R web application with a Shiny interface, built with an Agile methodology during a final-year Master’s internship.

  • Reachable from any machine, unlimited simultaneous users.
  • Results displayed immediately, no code to write for the researchers.
  • Modular architecture designed for maintainability.

Today

The tool is still online, maintained and extended by the INRAE team eight years later. It is cited in two peer-reviewed articles (The Plant Journal, New Phytologist) and two doctoral theses.
