I started working with Postgres in 2013 at a web hosting provider of educational solutions. Seduced by the features of the engine and the community I joined Dalibo in 2015 to devote full time to PostgreSQL.
Here you will find articles (mostly in French but I try to translate them) about PostgreSQL (but not only 😄). As well as the presentations that I could make during conferences. Feel free to open an issue on github ;)
