Backend Developer Virtual Internship

Backend postings ask for the same handful of things: clean API design, a schema that survives real data, authentication done properly, tests, and a service that can be deployed and observed. Your project is generated from those requirements for the industry you choose, and a technical lead who has shipped enterprise systems approves each sprint.

Reviewed by technical leads who have built and deployed enterprise applications on .NET and cloud

What you will work on

  • REST API design and versioning
  • Relational schema design, migrations and indexing
  • Authentication and authorisation
  • Validation, error handling and logging
  • Automated tests (unit and integration)
  • Containerised deployment with a CI pipeline
  • PRD and HLD approved before coding

Sample project brief

Illustrative — your project is generated for you

Order and inventory service for an e-commerce seller.

A mid-size seller runs on spreadsheets and oversells during sales. Build the service that takes orders, reserves stock atomically, handles cancellations and returns, and exposes reports to a dashboard.

  1. 1

    Sprint 1 — Schema and core API: design products, inventory, orders and customers; implement create/read endpoints with validation and migrations.

  2. 2

    Sprint 2 — Correctness under load: atomic stock reservation, idempotent order creation, auth with roles, and integration tests that prove no oversell under concurrent requests.

  3. 3

    Sprint 3 — Ship and observe: containerise, add a CI pipeline, structured logs and health checks, and write the deployment runbook.

Questions about the Backend Developer internship

Which language and framework?

The brief lets you choose from supported stacks (for example Node.js/Express, Python/FastAPI, Java/Spring Boot or .NET). The reviewer evaluates design and correctness, not the language.

Do I deploy to a real cloud?

You deploy inside the platform's environment; the sprint is scored on whether the service runs, passes its tests and is documented well enough for someone else to run it.

How long does it take?

Three sprints per project, two projects for the certificate, around 60–80 hours per project at your own pace.

What does the certificate show?

Score across sprints, reviewer sign-off, project summary and a public verification URL.
