Frontend vs backend developer: where to start

What a frontend developer does and what a backend developer does

A frontend developer builds what runs in the browser. A backend developer builds what runs on the server: the code that stores data and decides what the browser gets back.

MDN draws the line clearly. Client-side code is "written using HTML, CSS, and JavaScript" and "run inside a web browser", while server-side code handles "validating submitted data and requests, using databases to store and retrieve data and sending the correct data to the client" (MDN Web Docs).

The feedback loop is the biggest practical difference for a beginner. On the frontend you save a file and see the result. On the backend you send a request, read the response and check the database, which takes longer to get used to.

Do frontend or backend developers earn more in India?

Neither, reliably. Indeed India's averages, from salaries people reported themselves, currently put frontend ahead, which is the opposite of the usual claim that backend pays more.

Both samples are under 100 people, so treat the gap as noise rather than a trend. The city matters far more. Indeed's backend average for Hyderabad is ₹18,72,537 a year, against ₹6,55,308 for Delhi, a gap bigger than anything between the two roles.

So don't pick a side for the money. Pick the one you'll stay with long enough to build something good.

How many developers work only on one side

Few developers stay on one side. In the Stack Overflow Developer Survey 2025, 27% of the 43,560 people who answered called themselves full-stack, 14.2% back-end and only 4.3% front-end.

The India figures follow the same pattern. Of 2,536 respondents in India, 25.3% said full-stack, 14.7% back-end, 5.9% front-end and 19.6% were students.

Job titles blur in practice. A "frontend" intern still calls APIs and reads error responses, and a "backend" intern still has to check what the user sees. Go deep on one side and learn enough of the other to finish a feature end to end.

Which to learn first: a rule by background

Start from what you already know, not from salary charts. Use the row that fits you best.

If two rows fit, pick frontend. You'll need a page to show off a backend project anyway, and a deployed page is the quickest thing to put on a resume.

What interviews test on each side

Large companies test fundamentals on both sides as well as your framework. Amazon's prep page for student front-end engineers says interns get "one round of two interviews", each about 45 to 60 minutes, and the technical part covers "Data structures and algorithms" alongside "Front end tech (JavaScript/CSS/HTML)" (Amazon Jobs).

So choosing frontend doesn't get you out of algorithms at a company like that. It changes the second half of the interview: CSS layout and the DOM instead of database design. How much DSA you need for an internship covers the coding test itself.

For backend work, be ready to explain your HTTP status codes, how you modelled your tables and what happens when two requests change the same row. Have one project where you can answer all three from your own code.

What to build first on each side

Build one small project that a reviewer can open in under a minute. The first project matters more than the side you chose.

On the frontend, start with a responsive page and then a dashboard that loads data from a public API, with loading and error states. The frontend projects for your resume post lists five builds in order.

On the backend, build a small REST API with sign-up, login and three endpoints backed by PostgreSQL. A hostel mess-menu API works well, because you can explain every rule in it:

import express from "express";

const app = express();
app.use(express.json());

app.post("/menu", (req, res) => {
  const { day, meal } = req.body;
  if (!day || !meal) {
    return res.status(400).json({ error: "day and meal are required" });
  }
  // Save to PostgreSQL here, then return what was stored.
  res.status(201).json({ day, meal });
});

app.listen(3000);

The status codes are the point of that snippet. A bad request should get a 400 and a created item a 201; an API that answers 200 to everything is the first thing to fix.

How DevIt's Frontend and Backend tracks differ

DevIt runs both as separate online internship tracks, and the prerequisites follow the rule above. The Frontend Developer Internship needs no prior coding and starts with HTML, CSS and JavaScript, with React and Tailwind CSS on the 3-month plan. Its 1-month plan has 5 projects and 5 quizzes.

The Backend Development Internship expects basic JavaScript first. It covers Node.js, Express, PostgreSQL with Prisma, and authentication, and its 1-month plan has 3 projects, 1 quiz and 1 coding exercise.

Both are paid training programmes with no stipend. On 18 October 2026 each track page listed ₹199 for the 1-month plan and ₹299 for the 3-month plan, paid once. The internships page lists the other tracks, and are virtual internships worth it covers what to weigh before you pay for any online programme.
