The short version

Users never see the logic that keeps an application running, but they notice the moment it fails: a login that does not work, a form that loses their data, a page that shows the wrong result. In this internship at SkillzenLoop you will build that hidden layer. You will create APIs, store data safely and add the checks that keep a system fast, correct and secure.

• Week 1: set up the project, run the existing API locally and trace one request from the endpoint to the database
• Week 2: build a new REST endpoint with Node.js and Express, and test it with Postman
• Week 3: connect it to a database, add input validation and clear error responses, and protect the route with token-based login
• Week 4: write tests, document the endpoint for other developers and walk the team through your work in a code review
• Every day: commit your work to Git and share progress in a short check-in
