Backend Development Internship

In this backend development internship you design the API, model the database and handle the auth. Then watch the front-end interns build against it and tell you what you got wrong.

The work

Your API has real consumers in the same building

This is the difference that matters: the front-end and mobile interns build against your endpoints. Ship a bad contract and you will hear about it in the same afternoon.

  • 1You design the schema and endpoint contract first
  • 2You publish the API docs before writing the handlers
  • 3Front-end interns integrate and file real bugs
  • 4You version, fix and deploy without breaking them

No prior Node needed: weeks 1 to 3 cover JavaScript, Express and SQL from zero.

src/modules/orders/orders.controller.js
// Week 5: validation, pagination, real error codes
router.get('/v1/orders', auth('staff'), async (req, res, next) => {
  try {
    const { page = 1, limit = 20, status } = req.query;
    if (limit > 100) return res.status(400).json({
      error: 'LIMIT_TOO_LARGE', max: 100
    });

    const { rows, total } = await orders.list({
      page: Number(page), limit: Number(limit), status
    });

    res.set('X-Total-Count', total);
    res.json({ data: rows, page: Number(page) });
  } catch (err) { next(err); }
});
Skills

What you will be able to do after this backend development internship

01

JavaScript and Node

Async/await, modules, error handling and the runtime model behind it.

02

REST API design

Resources, verbs, status codes, pagination, versioning and a contract that lasts.

03

Database modelling

Normalisation, relationships, indexes and queries that stay fast at scale.

04

Authentication

JWT, refresh tokens, password hashing, roles and route-level permissions.

05

Validation and errors

Request validation, consistent error shapes and never leaking stack traces.

06

Testing

Unit and integration tests against a real test database, run in CI.

07

Deployment

Environment config, Docker, migrations and deploying without downtime.

08

Performance

Query profiling, N+1 problems, caching and knowing what to measure.

Curriculum

The 12-week backend development internship plan

Four phases. Each one ends in a deliverable that is reviewed and graded before the next opens.

Foundations

JavaScript, Express and SQL from the ground up.

  • JavaScript and Node fundamentals, async/await
  • Express routing, middleware and project structure
  • SQL basics: select, join, group, index
  • Git branching, pull requests and code review
Deliverable

A working CRUD service over a three-table schema, with seed data and a Postman collection.

The capstone

Every intern ships an API someone else depends on

You own the backend for a live Ezitech brief. Front-end and mobile interns build their capstones on top of your endpoints, which means your contract has to hold.

  • Documented REST API with real consumers
  • Modelled database, auth and role permissions
  • Deployed, tested and monitored

The Ezitech model

What the backend development internship includes

Three things that make this different from a course you watch on a screen.

Live client briefs

You work on real Ezitech projects with real deadlines and real revision rounds, not recycled practice exercises.

A mentor, not a playlist

Weekly reviews with someone who does this work for a living, plus a team of interns around you to build with.

Portfolio and experience letter

You finish with shipped work you are allowed to show and a letter that says exactly what you delivered.

And you leave with

  • Verified certificate

    Issued by Ezitech Institute and verifiable by employers.

  • Experience letter

    On company letterhead, stating exactly what you delivered.

  • A deployed API

    A documented, deployed service with a public repository.

  • Interview preparation

    CV rewrite, portfolio case study and a technical mock interview.

  • A route into the team

    Top performers are considered first for paid junior roles.

  • Confidence in review

    Twelve weeks of defending your own work to a senior practitioner.

Built for you if

  • You are an undergraduate or fresh graduate in CS, IT or SE
  • You know basic programming logic in any language
  • You prefer data and logic to pixels
  • You want a deployed service on your CV, not a localhost demo

Not a fit if

  • You want a certificate without doing the work
  • You cannot give 25 hours a week for 12 weeks
  • You are looking for a purely theoretical course
  • You want to skip review and work alone

Contact Ezitech
Do I need to know Node.js or SQL already?
No. Weeks 1 to 3 cover JavaScript, Express and SQL from the ground up. If you can write a loop and a function in any language, you can start this track.
How many hours a week does it take?
A minimum of 25 hours across 12 weeks, split between onsite sessions, mentor reviews and independent work. Interns who treat it as full-time finish with noticeably stronger portfolios.
Is it remote or onsite?
Hybrid. Onsite days run at the Ezitech office in Rawalpindi; the rest of the week is remote with scheduled check-ins. Candidates outside Rawalpindi and Islamabad can complete the track fully remotely if they attend the weekly review calls.
Will I actually deploy the API, or just run it locally?
You deploy it. Week ten covers Docker, environment configuration and a real deployment with migrations, logging and monitoring. A live URL is part of the deliverable.
Can final-year students apply?
Yes, and many do. The capstone is regularly used as a final-year project because it is built from a real brief with real requirements. Agree the scope with your mentor in week one if your university has a set submission format.
How do I apply?
Register on the Ezitech intern portal, choose the Backend track, and complete the three-step form with your education details and CV. Shortlisted candidates get a short screening call before the intake starts.
