Middleware explanation assistant
Auchan reported rewriting approximately 30% of its middleware in 3 months with Gemini assistance
Problem
Legacy code lacked documentation.
Approach
Auchan built a Gemini assistant using middleware code and its existing documentation to answer developers' questions about logistics workflows and the effects of code changes. Developers rewrote approximately 30% of the middleware and deployed the rewritten flows during the summer.
Results
3months rewriting approximately 30% of middleware; unaided year was estimated
Takeaway
The assistant helped developers understand poorly documented code before rewriting it. Auchan estimated that the work would have taken a year without generative AI.
