A full-stack SaaS platform that delivers real-time project intelligence by reading movement, pressure, and authorship of work over time rather than reporting static task status. Built end-to-end with deliberate architectural decisions: PostgreSQL row-level security, broker-free real-time synchronization via database primitives, multi-tenant isolation enforced at the schema layer, and a contrast-measured design system. PULSE demonstrates comprehensive full-stack engineering when nothing is inherited from templates and every architectural choice is made intentionally.
