Job Board Platform

Part of the Full Stack Developer Roadmap

In short

A job board has two kinds of users who want opposite things. Employers post and review, candidates search and apply. Getting roles and ownership right is the whole project.

A platform with two user types — employers posting jobs, candidates applying — practice for role-based features and more complex, multi-sided data relationships.

The purple blob at a desk matches folders from briefcases on one side and backpacks on the other.

Think of it like this

The college placement cell

Companies drop job details at the placement cell. Students drop their applications. The coordinator makes sure each company sees only its own applicants, and no student applies to the same company twice.

Watch it happen

Two roles, one database

Employer

API

Database

Candidate

POST /jobs

1/6An employer posts a job. The API checks the role is EMPLOYER and saves employer_id with it.

The big ideas

What you need to know

Roles on every route

Each endpoint says who may call it. Check the role on the server, not just by hiding buttons.

Ownership beats role

Being an employer isn't enough. The job must belong to you before you see its applicants.

Search with filters

Location, remote, salary and skills filters with Postgres full-text search or a simple ILIKE to start.

Status updates

Applications move through applied, shortlisted, rejected. Email the candidate on each change from a background job.
