Organ, collaborative project management: case study

[01]Context and principle

Organ is a project management platform built by a team of three within Voxel Studio. Each project is divided into "organs": autonomous sub-spaces with their own members, roles and permissions. It includes a Kanban board, a list view, statistics, an audit log and a built-in AI assistant.

Give each collaborator only what they need: a member only reaches the organs where they hold a role. A role can be copied from one organ to another, then its permissions are adjusted organ by organ.

[02]Architecture

Symfony 8 backend, Angular front end, native Android app in Kotlin (Compose).

Polyglot persistence: MySQL for relational data, MongoDB for the audit log. Depending on configuration, attachments are stored in GridFS or sent directly to the user's own Drive.
Real time: Updates pushed through Server-Sent Events (Mercure) to web and Android.
Fine-grained permissions: Hybrid RBAC: global roles plus local permissions for each organ.

Other technical and functional choices

Google sign-in (OAuth 2.0)On the web and on Android.

Built-in AI assistant (commands /create, /edit, /role, /ask)A switch lets the user authorize it to act on their behalf.

"Bring Your Own Storage"Depending on configuration, files are stored in GridFS or go straight to the user's own Google Drive; in that case Organ only keeps the metadata.

Revocable active sessions; account deletionImmediate deactivation, then permanent erasure after 30 days without signing in again (GDPR).

[03]Kanban and tasks

Columns by status, priorities, tags and due dates; task sheet with its activity history.

Kanban: the status changes by drag and drop between columns.

[07]Results and limits

Results

My share of the project is given in the fact sheet at the top of the page: figures taken from the repository, verifiable on the GitHub contributors graph.

Limits

The screenshots use fictional demo data; the video was recorded on a demo account with personal data pixelated.
Commit and code shares describe how the work is split in the repository, not anyone's quality. The code share excludes lockfiles, generated files, migrations, JSON/assets and documentation.
