# nishanthrao01/job-management-system architecture > Architecture diagram of the GitHub repository nishanthrao01/job-management-system, generated by GitDiagram from its file tree, README and a sample of source files (last updated 2026-11-12). It is an AI-made overview: check details against the source. - Interactive diagram: https://gitdiagram.com/nishanthrao01/job-management-system - Repository: https://github.com/nishanthrao01/job-management-system ## Overview Job Management System is a full-stack SaaS platform connecting clients with recruitment associates who manage job-application workflows. Users register or sign in, then role-protected dashboards support job tracking, subscriptions and payments, and chat; administrators manage users and review operational records. The backend exposes REST routes backed by controllers and MongoDB models, with Redis caching documented for dashboard queries. Sampled files show route dispatch, job operations, payment verification, and socket messaging; unsampled subsystems are included only where the README or server wiring establishes them.
