About Frédéric

Hello.

I am the author of a book in French on the Go language, published by Dunod in the InfoPro collection: "Programmer avec Go - les fondamentaux du langage"; and I have been teaching Go and production techniques at EEMI since 2018. Discover it at
I am a specialist in backend development in Go and PHP, a Drupal core contributor since 2005, maintainer of the XML-RPC subsystem since Drupal 4.7, the MongoDB module since Drupal 6, and a contributor to the development of Drupal 11.

I have been involved in the French Drupal community since 2008, a founding member of the Drupal France et Francophonie Association, and I speak at most Drupal events in Europe: Drupagora, Drupal Meetup, DrupalCamp, DevDays, Drupal Hack Camp, DrupalCon, mainly on issues of quality, security, and performance.

The missions entrusted to me are mainly of two types:

- Expertise on software and infrastructure architecture designs for backend performance issues, mainly on Go, Drupal, Symfony, or MongoDB. In this capacity, I have acted as lead developer/consulting architect, coach, or auditor on the majority of major French media sites: print, television, radio, pure players. These are expertise missions, occasional and short-term, available urgently 7 days a week.

- More conventional development projects as Senior or Staff Engineer, on a fixed-price or time-and-materials basis, on Go, Drupal 9/10, Vue.js, React, or Meteor.js. Rates vary depending on the technology, project duration, possible publicity, etc.: preferably for medium or long-term missions.

I work throughout Europe and the United Kingdom for occasional expertise missions, and in the Ile de France or Rhône-Alpes region for longer projects.
