Work with existing codebases and understand their architecture

Participate in code reviews and follow established coding practices

Write reusable and maintainable components and services

Test APIs and application functionality

Work with Git and collaborate with the development team

What We're Looking For

Strong fundamentals in JavaScript

Working knowledge of Node.js and React.js

Basic-to-good understanding of REST APIs

Basic understanding of databases, including CRUD operations, relationships, and indexing

Understanding of Node.js asynchronous programming, promises, async/await, and the event loop

Understanding of routing, controllers, services, middleware, validation, and error handling

Basic understanding of authentication and authorization

Understanding of how frontend applications communicate with backend APIs

Basic TypeScript knowledge and understanding of why it is used in larger applications

Familiarity with Git/GitHub, including commits, branches, pull requests, and resolving conflicts

Ability to read, understand, debug, and modify existing code

Ability to use logs, browser developer tools, and API testing tools such as Postman

Strong problem-solving skills and willingness to learn

Good to Have

Experience with any of the following will be an advantage:

Next.js or NestJS

Prisma

MongoDB aggregation and indexes

PostgreSQL

JWT authentication and role-based access control

Redis / caching

Background jobs or queues

WebSockets / Socket.IO

Docker

Basic cloud or deployment knowledge

Third-party API integrations

File storage and upload systems

GitHub Actions or basic CI/CD concepts

The Kind of Developer We're Looking For

We are not looking for someone who only knows how to follow tutorials or YouTube projects. You should be able to explain the fundamentals behind what you build.

You should have a basic understanding of questions such as:

What happens when a request reaches a Node.js server?

How does Express middleware work?

How does a React application communicate with an API?

What happens between a frontend button click and a database update?

What is the difference between authentication and authorization?

Why do we use controllers, services, and modules in a backend?

How does asynchronous code work in Node.js?

What happens when an API returns an error?

How would you structure a small backend application?

How do databases and indexes affect API performance?

You don't need to know everything.

Strong fundamentals, curiosity, and the ability to understand an existing codebase are more important than knowing a long list of technologies.

If you enjoy understanding how systems work, building features, debugging problems, and learning through real-world development, this internship will give you the opportunity to work with a development team and build practical software engineering skills.
