about this room

Three Java talks at Spring Meetup Paris, hosted by Doctolib.

Abadallah Ghdiri explains (in English) how Doctolib's teams migrated 60 microservices to Spring Boot 4.0 without every team doing it service by service, and what Claude Code did and didn't help with. Max Tekpa covers Project Leyden and JEP 483, Java's answer to slow start-up. Victoire De La Charrière shows why test coverage isn't enough and how mutation testing tests your tests.

At Doctolib, 54 Quai Charles Pasqua, Levallois-Perret. Doors 18:30, talks 19:00, buffet after. Free on Meetup. Bring photo ID to get in. Two talks in French.
