Work is organised as Workspace → Projects → Tasks. Tasks have a status, a priority, an assignee and a due date, and are shown on a Kanban board. Each workspace has members with a role: owner, admin, member or guest. There is a chat per workspace and direct messages between users.

The backend is Flask, split into blueprints (auth, workspaces, projects, tasks, direct messages). It talks to PostgreSQL 17 with plain SQL through psycopg, and uses Socket.IO for the chat. The frontend is HTML, CSS and vanilla JavaScript with no build step. Passwords are hashed with Argon2, sessions are cookie-based, and Redis backs the rate limiter. In production it runs on Docker Compose behind Caddy, with Gunicorn serving Flask.

Status: not finished. It is the project for my RNCP5 certification file, due 31 December 2026, and a demo is online. The tests use test doubles for the database: they cover selected authentication, permission, validation, messaging and health-check paths, but not the PostgreSQL queries or the browser rendering, which still need a running database and manual checks.
