Job Portal

A job application platform where candidates submit applications and admins review, approve, or reject them. Centralizes hiring workflows in one place. Built server-rendered for speed, it tracks application status, manages candidate pipelines, and generates reports for hiring teams.

Build StackNode.js, Express, EJS (server-side rendering), MongoDB, Passport.js, Bootstrap

Challenges

  • Preventing duplicate applications while handling concurrent submissions

  • Tracking application status through multiple stages (submitted → reviewed → approved)

  • Generating reports without slowing down the live application system

  • Managing admin and candidate permissions cleanly without fragmented logic

Solutions

  • Unique compound index on (candidate_id, job_id) to block duplicates at database level

  • Status enum with timestamp tracking; audit trail of state changes

  • Report generation via aggregation pipeline; scheduled background jobs

  • Middleware-based permission checks; conditional EJS template rendering per role
