## Backend-Focused Full-Stack Mobile Developer Internship

We are looking for a Backend-Focused Full-Stack Mobile Developer internship to help build and take ownership of a production-ready mobile application.

### What you'll work on

Design and develop scalable backend architecture and APIs.

Work with Node.js, TypeScript and PostgreSQL/Supabase.

Set up and manage Supabase Authentication, Database, Storage and Realtime.

Design database schemas, relationships, indexes and secure data access.

Implement authentication, authorization, business logic and API integrations.

Connect backend services with a React Native + Expo mobile application.

Ensure application features work end-to-end with real data.

Handle file uploads, notifications, realtime functionality and other backend services where required.

Test APIs and complete application flows, identify bugs and fix them.

Debug frontend-backend integration issues.

Perform basic performance and scalability checks and identify potential bottlenecks.

Ensure the application works reliably across Android and iOS.

Follow good practices for security, error handling, setting management and deployment.

Use Git/GitHub for development and collaboration.

### What we're looking for

Good understanding of backend development and APIs.

Practical experience with Node.js and TypeScript.

Valuable understanding of PostgreSQL and database design.





Hands-on knowledge of Supabase or willingness to work with it.

Basic-to-good understanding of React Native / Expo and how mobile apps communicate with backend systems.

Understanding of authentication, authorization, API security and data validation.

Ability to test, debug and troubleshoot backend and mobile integration issues.

Basic understanding of mobile performance, networking and device limitations.

Ability to think about scalability, reliability and production readiness, not just getting features to work.

Comfortable taking ownership of backend-related implementation from development through testing and deployment.

### Good to have

Experience building and deploying production mobile applications.

Experience with realtime systems, notifications, file storage and third-party APIs.

Experience with automated testing.

Understanding of CI/CD and cloud deployment.

### Important

This is not a backend-only role where you simply build APIs and hand them over.

You will be expected to understand how the backend works with a mobile application, integrate it properly, test the complete functionality, debug issues, and help ensure the application is reliable and production-ready.

Primary focus: Backend + Database + Mobile Integration + Testing + Production Readiness

Tech Stack: React Native / Expo • TypeScript • Node.js • PostgreSQL • Supabase • Git/GitHub
