Full-Stack Developer fresher requirements (2026)

These are the published requirements FresherHub scores a Full-Stack Developer against (role version 2). The weights are fixed in the role definition; AI never changes them.

The short answer

A requirement counts fully only when there is proof you can point to, such as a repository, a deployed project or a notebook. A skill you only list counts for much less.

How the score is weighted

Full-Stack Developer score weights
Area	Share of your score	Requirements
Fundamentals	10%	2 (1 must-have)
Frontend	20%	2
Backend	20%	3 (1 must-have)
Databases	15%	2 (1 must-have)
Production	20%	4 (1 must-have)
Professional	15%	3

Within an area, each requirement has its own weight. Your readiness is the weighted sum, so the share shown on each requirement below is how much of the overall score it carries. How scoring works explains the formula.

Requirements, area by area

Fundamentals · 10% of your score

JavaScript & TypeScript proficiency

Must-have

6% of the overall score

Comfortable with modern JavaScript/TypeScript across both client and server code — async/await, error handling, and types.

What counts as proof

Resume lists JavaScript or TypeScript under skills or experience.
Public repositories show meaningful JavaScript or TypeScript usage.

How to close the gap

Share a TypeScript type/interface between your frontend and API code

Git & version control

4% of the overall score

Regular, incremental commits and branch hygiene visible on GitHub.

What counts as proof

Consistent recent contributions (not a single bulk dump).

How to close the gap

Keep small, descriptive commits across your primary full-stack repo

Frontend · 20% of your score

React UI connected to a real API

12% of the overall score

Builds a usable React UI that reads and writes through a real backend API, not static/mock data.

What counts as proof

Resume claims React with project or internship context.
Repositories depend on React in package manifests.

How to close the gap

Confirm every screen in your primary project reads/writes through your own API (no leftover mock data)

Client state & data fetching

8% of the overall score

Manages server data with a real client-side pattern (React Query, Redux) so loading/error states are handled deliberately.

What counts as proof

Resume lists a state/data-fetching library.
Repos depend on a state/data-fetching library.

How to close the gap

Replace a raw useEffect fetch with React Query (or equivalent) in your main project

Backend · 20% of your score

Node.js API design

Must-have

8% of the overall score

Builds a REST (or GraphQL) API on Node.js with clear routing, request handling, and resource design.

What counts as proof

Resume claims Node.js with project or internship context.
Repos depend on Express, Fastify, or NestJS.

How to close the gap

Document your primary API's routes, auth, and example requests

End-to-end authentication

7% of the overall score

A real login flow that works front-to-back: client auth UI, server-side session/JWT issuing, and protected routes on both ends.

What counts as proof

Project shows a login/register flow with token or session-based protected routes on both client and server.

How to close the gap

Document how auth works end-to-end (client token storage, server verification, protected routes)

Request validation & error handling

5% of the overall score

Validates inputs server-side and surfaces structured errors that the frontend actually displays, instead of silent 500s.

What counts as proof

Code or docs show schema validation (Zod, Joi, class-validator, etc.) with matching frontend error display.
Repos depend on a request validation library (zod, joi, class-validator…).

How to close the gap

Add request validation on the API and render the resulting errors in the UI

Databases · 15% of your score

Relational database / SQL

Must-have

9% of the overall score

Practical PostgreSQL (or strong SQL) evidence backing the app's data — schema design and real queries, not resume-only claims.

What counts as proof

A project uses PostgreSQL, Prisma, Sequelize, Knex, or raw SQL migrations.
Resume claims PostgreSQL/SQL — alone is weak without project evidence.
Repos depend on a relational driver or ORM.

How to close the gap

Document your PostgreSQL schema (tables, relations, indexes) in the project README

Document database usage (MongoDB)

6% of the overall score

Models data with MongoDB/Mongoose (or similar) where a flexible/document shape fits the project.

What counts as proof

Projects use MongoDB client or ODM with real schemas.

How to close the gap

Document schema design decisions for any MongoDB collections in the README

Production · 20% of your score

Automated testing (frontend + backend)

6% of the overall score

Automated tests on both the API (unit/integration) and the UI (component tests) — not manual clicking only.

What counts as proof

Repositories contain test files and a test runner configuration.

How to close the gap

Add at least one API test and one UI component test to your primary project

Containerization (Docker)

4% of the overall score

Dockerfile (and ideally compose) so the full stack — API, DB, and optionally frontend — runs outside the laptop.

What counts as proof

Repository includes Dockerfile or docker-compose.yml.

How to close the gap

Add a docker-compose.yml that runs the API and database together

Deployed full-stack app

Must-have

6% of the overall score

The whole app is deployed and reachable — frontend and API both live, not just a backend health check.

What counts as proof

Project has a live URL or deploy platform evidence for both frontend and API.

How to close the gap

Deploy both your frontend and API and confirm they talk to each other in production

CI/CD basics

4% of the overall score

Automated checks on push (tests/lint) via GitHub Actions or equivalent, across the repo(s).

What counts as proof

Repository has CI workflow configuration.

How to close the gap

Add a GitHub Actions workflow that runs tests on push

Professional · 15% of your score

GitHub project presentation

6% of the overall score

Strongest repo is evaluable quickly: README with setup, architecture, and both API and UI overview.

What counts as proof

Primary full-stack repo README covers setup, architecture, and API/UI overview.

How to close the gap

Rewrite your strongest full-stack README for recruiters
Add a GitHub profile README oriented to Full-Stack Developer

Resume project positioning

5.3% of the overall score

Project bullets convey full-stack ownership (frontend, API, database) and outcomes, not only 'worked on a project'.

What counts as proof

Resume project section names the stack end-to-end and impact, not generic phrasing.

How to close the gap

Rewrite full-stack project bullets to show ownership across the stack

LinkedIn role positioning

3.8% of the overall score

Headline/About and featured work signal Full-Stack Developer, not a generic student profile.

What counts as proof

Headline or About names the full stack and target role.

How to close the gap

Update LinkedIn headline to Full-Stack Developer + stack
Rewrite LinkedIn About with real end-to-end projects and target role

Listing a skill vs proving it

Each requirement is scored by the best piece of evidence for it. A skill named in your resume's skills list is a claim and counts for 25%. Work we can see counts for more: observed 60%, demonstrated 80% and strong 100%. Read Am I job-ready? for a self-check you can do today.
