Smart Contract: Create and Apply for Jobs

Explore how to extend a Solidity smart contract to enable users to create and apply for job listings in a decentralized job board. Understand profile validation, job offer creation, application tracking, and implementing enums and events. Test these features within the Remix IDE to build a functional, full-stack dApp.

We'll cover the following...

In this lesson, we’ll focus on adding extra features to our smart contract. Currently, we can create profiles; now we’ll extend this to let users create listings for jobs or apply for them.

Creating a job offer

We’ll begin with the function for creating job offers. Paste the updated code ...
