React JS Internship
Everyone can render a list. This track is about component boundaries, state that does not tangle, and a build that stays fast as the product grows.

Where React apps actually go wrong
Not in the syntax. In state that lives in the wrong place, effects that fire twice, and a bundle that grows to 2MB because nobody checked. Review here focuses on exactly that.
- 1You get a Figma file and a real API to build against
- 2You break the design into components before coding
- 3Your mentor reviews state placement and re-renders
- 4You test, measure the bundle and deploy
No prior React needed. Weeks 1 to 3 cover JavaScript and React fundamentals from zero.
// Week 7: server state separate from UI state export function OrderTable({ status }: { status: Status }) { const [page, setPage] = useState(1); const { data, isPending, error } = useOrders({ page, status }); if (error) return <ErrorState onRetry={refetch} />; if (isPending) return <TableSkeleton rows={8} />; if (!data.length) return <EmptyState label="No orders yet" />; return ( <Table rows={data} onPage={setPage} renderRow={(o) => <OrderRow key={o.id} order={o} />} /> ); }
Eight things you will actually be able to do
JavaScript and TypeScript
Closures, async, modules, and typing components so refactors are safe.
Component design
Composition, props, boundaries and building a component library, not a page of divs.
Hooks and state
useState, useEffect, useMemo, custom hooks, and where state should actually live.
Server state
React Query, caching, invalidation, optimistic updates and stale data.
Routing
Nested routes, layouts, protected pages, loaders and code splitting.
Forms
Controlled inputs, validation, error surfacing and forms that do not lose data.
Testing
React Testing Library, testing behaviour rather than implementation.
Performance
Re-render profiling, memoisation, lazy loading and bundle budgets.
The 12-week plan
Four phases. Each one ends in a deliverable that is reviewed and graded before the next opens.
JavaScript and React
The language first, then the library.
- Modern JavaScript: modules, async, destructuring
- React components, props, JSX and rendering
- useState, useEffect and the rules of hooks
- Vite, npm and Git pull request workflow
Four interactive components built from a Figma file, with proper prop typing.
Real applications
Routing, data and everything between screens.
- Routing, nested layouts and protected pages
- Fetching with React Query, caching and invalidation
- Loading, empty, error and retry states everywhere
- Forms, validation and controlled inputs
A multi-page application running on a live API, with complete state coverage on every screen.
Architecture
Making it survive its own growth.
- TypeScript for components, props and API types
- Custom hooks and extracting shared logic
- Component library, tokens and consistent styling
- Auth flows, roles and conditional rendering
A typed, componentised codebase with a documented internal component library.
Ship it
Tests, speed and a public URL.
- Testing Library, user-event and CI on every PR
- Re-render profiling and memoisation where it counts
- Code splitting, lazy routes and bundle budgets
- Portfolio case study, CV rewrite, mock interview
A deployed React application with tests passing in CI and a measured Lighthouse score above 90.
Every intern ships one real interface
You build the front end for a live Ezitech brief against an API the backend interns maintain. Their contract changes; your code has to cope.
- A typed React codebase with a component library
- Running on a real API with real auth
- Deployed, tested and measured







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 interface
A live React application 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 want the highest-demand front-end skill in the market
- You care how an interface feels, not just that it renders
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
