Build a Job Application Tracker with MongoDB

In today’s job market, managing multiple applications can be difficult. This project builds a job application tracker using MongoDB and mongosh to manage a hiring pipeline from the terminal. Each application is stored as a flexible document, similar to how data engineering workflows handle irregular, semi-structured data that does not fit traditional tabular formats.

As we work through the project, we practice every core MongoDB CRUD operation: inserting documents with insertOne() and insertMany(), filtering results with find(), modifying records with updateOne() and the $set operator, and removing entries with deleteOne(). By the end, we bring it all together in a formatted application board that reads every document in the collection and displays only the fields present on each record, putting MongoDB's schema flexibility on full display.
