Current Projects

View all my code here and some of it also there. See also my profile on GitHub.

Deuxfleurs, a self-hosted platform for chat, email, collaboration and file storage, where we use techniques from distributed systems to build fault tolerance. Main page.

Garage, a work-in-progress distributed object store, meant to run on commodity hardware and provide integrity, redundancy and fault-tolerance. Code.

Bottin, a LDAP server used on Deuxfleurs, that stores its data in Consul’s highly available key-value datastore. Link.

Easybridge, an easy to set-up bridge for talking to all your IM contacts through Matrix (currently supports XMPP, IRC, Mattermost and Facebook Messenger). Currently on hold, has many bugs. Code., a Cryptpad instance hosted on this server. Link.

Dancing: Rock 4 temps, rock 6 temps, west coast swing.

Music: I’d like to play more, but I’m lazy.
