MERN Stack Internship
One JavaScript codebase from the database to the browser. You build the API, the React front end and the deployment, and you own every bug in between.

Full stack means you cannot blame the other side
When the list renders wrong, it might be the React state, the Express handler or the Mongo query. Learning to find out which is the actual skill this track builds.
- 1You model the collections and design the API contract
- 2You build the Express API and test it independently
- 3You build the React client against your own API
- 4You deploy both and fix what only breaks in production
No prior React or Mongo needed. Weeks 1 to 3 cover JavaScript and both from zero.
// Week 7: client state, cache, error boundaries export function useOrders({ page, status }) { return useQuery({ queryKey: ['orders', page, status], queryFn: async () => { const res = await api.get('/v1/orders', { params: { page, status, limit: 20 } }); return res.data; }, keepPreviousData: true, staleTime: 30_000, retry: (count, err) => err.status !== 401 && count < 2 }); }
Eight things you will actually be able to do
Modern JavaScript
ES modules, async/await, destructuring and the patterns both halves share.
MongoDB modelling
Documents, references, indexes and when embedding beats joining.
Express APIs
Routing, middleware, validation, pagination and consistent error shapes.
React fundamentals
Components, hooks, lists, forms and rendering behaviour you can reason about.
Client state
Server state with React Query, local state, caching and optimistic updates.
Authentication
JWT, refresh tokens, protected routes and storing tokens safely.
Testing
API integration tests plus component tests with React Testing Library.
Deployment
Environment variables, CORS, hosting the API and the client, and CI.
The 12-week plan
Four phases. Each one ends in a deliverable that is reviewed and graded before the next opens.
JavaScript and the stack
The language, then each letter of MERN.
- Modern JavaScript, modules, async/await, npm
- Node and Express: routes, middleware, error handling
- MongoDB and Mongoose: schemas, queries, indexes
- Git branching, pull requests and review
A working CRUD API over two collections, with seed data and a tested Postman collection.
React front end
Turning the API into an interface people can use.
- Components, props, hooks and controlled forms
- Routing, layouts and protected pages
- Fetching, loading, empty and error states
- Styling, responsive layout and reusable components
A React client that lists, filters and creates records against your own API.
Auth and real features
Where the app becomes a product.
- JWT auth, refresh tokens and protected routes
- Roles, permissions and conditional UI
- File uploads, search, pagination and sorting
- React Query caching and optimistic updates
An authenticated app with two roles, uploads, search and a cache that does not go stale.
Ship it
Tests, performance and a public URL.
- Integration and component tests running in CI
- Bundle size, lazy loading and Lighthouse scores
- Deploying the API and client, CORS and env config
- Portfolio case study, CV rewrite, mock interview
A deployed full-stack application with a live URL, CI passing and a public repository.
Every intern ships one full-stack product
You own an entire Ezitech brief front to back: database design, API, React client and deployment. There is no other team to hand the hard part to.
- MongoDB schema, Express API and React client
- Authentication, roles, uploads and search
- Deployed with a live URL and CI







What every Ezitech intern gets
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.
Verified certificate
Issued by Ezitech Institute and verifiable by employers.
Experience letter
On company letterhead, stating exactly what you delivered.
A deployed full-stack app
A live URL, an API and one repository you own end to end.
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 want to be employable as a full-stack developer
- You would rather own a whole product than one layer
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
