Mercury Embroidery

Task assignment, revision history, designer timing and submitted artwork need to live in one reliable workflow. Manual tracking cannot show the true time spent per designer, client and period or safely preserve every version of the work.

A React SPA backed by a secure Spring Boot modular monolith. REST remains the source of truth, STOMP WebSocket events trigger live refetches, PostgreSQL stores the complete workflow history, and local or S3-compatible storage retains submitted files.

Keeping timing correct through concurrent task opens, approved breaks, manager pauses, submissions and multiple revision rounds — while ensuring each designer can have only one active round and can access only their own work.

Server-time calculations merge every pause window before subtracting it from elapsed time. Database constraints enforce one active round, submission is the only event that stops the timer, and task totals are recalculated as the sum of every completed round.
