A full-stack web app that enables team members to maintain private, personal journals within a collaborative workspace. Built using Next.js App Router and powered by Supabase, the app supports secure user authentication, journal entry creation, optional image attachments, and fine-grained access control using Row-Level Security (RLS). This app addresses a key gap in team tools: giving individuals a private space to reflect, document work, or note personal insights—without relying on task-based or public platforms.
