How statistics are calculated
We count how many offers each candidate received and for what salary. For example, if a Full Stack Web developer with Redux with a salary of $4,500 received 10 offers, then we would count him 10 times. If there were no offers, then he would not get into the statistics either.
The graph column is the total number of offers. This is not the number of vacancies, but an indicator of the level of demand. The more offers there are, the more companies try to hire such a specialist. 5k+ includes candidates with salaries >= $5,000 and < $5,500.
Median Salary Expectation – the weighted average of the market offer in the selected specialization, that is, the most frequent job offers for the selected specialization received by candidates. We do not count accepted or rejected offers.

What is a Full-stack Developer?
A Full stack developer is a technician skilled in both front end and back end of a software application. Full-stack developers have thorough knowledge of technologies used to implement features in different components or layers of a software product.
Full-stack Developers should have an understanding of the following:
Presentation Layer
The layer deals with the front end part of the application, i.e., user interfaces
Business Logic Layer
The business logic layer represents the application backend part, for example, the data validation, the messages going from the front end to the back end and vice versa.
Database Layer
This layer deals with the database connectivity with the application’s front end.
So, being a Full-stack developer does not mean you need to be expert in all these technologies; but you should be having an idea of how client as well server side things are working in the technologies that you are using to develop your app.
Business has started in for services called Full-stack development giving up the thought to hire different professionals to develop a software app.
Front End Technologies
As front end technologies are becoming more and more vital in product development, while the speed of demands on digital solutions has been skyrocketed, the world is no longer asking “what?” to analyze if a product was successful or not. Instead, it asks “how did it feel?” to evaluate the same.
Front end technologies are leveraged for the front end part of a software product, by the user. Full-stack developer needs to have clarity regarding what an application should look like and what is the flow of an app.
HTML/CSS
HTML was created for representing web apps and web pages by using an impression called Hypertext Markup Language. CSS was created for representing how HTML events should be shown on the screen by an impression called Cascading Style Sheets. And sometimes CSS can control the layout of multiple web pages at once.
Bootstrap
Bootstrap is an responsive, multi-purpose, mobile first CSS framework used to develop websites and web applications. It allows websites to adjust gracefully to fit any screen sizes and devices. This open source tool provides lots of CSS, JavaScript based design templates to facilitate the development by saving developers time of writing codes.
AngularJS
AngularJS, which uses JavaScript, is an open source framework that can overcome many obstacles that present themselves in building single-page applications.
React
React is a JavaScript library for the development of user interfaces, which is fundamentally equipped to offer very good rendering both on the server and on the side of the client.
Backend Technologies
Every software application consists of two sides: frontend and backend. More often than not, the app that you see in front of you is merely a frontend. The rest of it – what enables organized storage of data, robust functioning of the application on client side, etc – is the backend.
Backend is the one that communicates with the front end and transfers information to be displayed on the web app. If you fill out a form in the app, request to buy an item or save an item in your card, front end of the app sends the request to the back end, which fetches that data and returns it.
PHP
This it does, by parsing the incoming request (the query string or the body of the POST request) and executing the specified program, much as any general-purpose programming language would for any such task – such as generating dynamically a page for a website or web app, receiving form data, setting session cookies, etc.
Java
Java is an object-oriented language that runs on multiple platforms such as Windows, Linux, MAC and so on. The language can be used as a development environment for mobile app, web app, desktop app, games, database connection , web servers and application servers as well.
Python
Python is a general purpose and interpreted language and used by its developers to design web applications and link to database systems. It is human-friendly because it enables programmers to write less lines of codes with respect to other languages and is similar to English.
.NET
.NET is an open-source cross-platform that is used by developers to create web apps, mobile apps, desktop apps, microservices and gaming apps, and IoT apps. .NET requires the C#, Visual Basic or F# programming language to build apps.
NodeJS
NodeJS is a application that used to create network applications with the ability of scaling. NodeJS is also a javascript runtime that built into an open source, cross-platform server environment capable of running on Linux, Mac OS X, and Unix platform.
Go
It’s an open source Google programming language for development of general-purpose programming language that write a simple and efficient software applications.
Database
It’s pretty exceptional for existing software products to function without having some sort of database to store the actual data. If you’re a Full-stack developer, you should know about at least one or two database systems, and how to talk to it.
MySQL
MySQL is a free RDBMS (Relational Database Management System) that uses SQL to insert, retrieve and manage data stored in the database.
MongoDB
MongoDB is an open-source cross-platform document-oriented database which belongs to a class of databases called NoSQL. It provides high performance, high availability and easy horizontal effortless scalability, The MongoDB coding is performed in C++.
PostgreSQL
An open-source RDBMS is known as PostgreSQL. It can accommodate workloads, from a single machine app to data warehousing or distributed web services, with many concurrent users.
SQL Server
SQL Server is a relational database management system that maintains and retrieves data based on requests made by application software running on the same system, or on a system across the network.
DevOps
The term ‘DevOps’ is a hybrid blend of two words – ‘development’ and ‘operations’ – with a specific interpretation. Used as a set of software development practices, it means uniting development and operations teams to get code into production faster in an automated and repeatable manner.
It helps developers to play their full role in the complete development cycle of any software from design and development to delivery of the same.
It also helps organisations to improve their pace in delivering digital solutions and applications.
A Full-stack developer should understand the DevOps lifecycle and the DevOps process versus traditional process he participated in the development of it.
Understanding of horizontal concerns within the application
Request/Response Tracing
Request/response tracing will allow the developers to see what is happening to a particular request to the software application.
File Storage
A file storage system is a service that stores data stored in files and folders in a hierarchical order. The system retrieving it and the system storing it the same format in which it is presented. A Full-stack developer needs to know different kinds of file storage services such as Google cloud, Microsoft Azure, AWS and other for store the data in specific format.
Security
In developing any type of software, security is the most important thing to make your software application secure and not breaking any security standards. As a Full stack developer you should know about encryption, public and private key cryptography, SHA 128 and decryption etc.
Logging
The technical definition of logging is to record processes, input and output of data and actions, which an application executes. Whenever we develop any software product, we barely think about logging or don’t have any technical knowledge about logging. A core duty of a Full-stack developer is to create log file and store logs in it.
Understanding of Compliances
While developing a software application, different types of data are involved such as personal, financial, audit, transactional, high sensitive. Therefore, identification and grouping of data are the two mandatory activities of software development. Since software-based applications are critical for modern businesses. It’s extremely important to protect the various types of data such as financial and personal data. Finally requirement of the organisation also include the compliances of different regulatory bodies like SEC, ISO and SOC 2.
So, Full-stack developer yourself need to learn about the compliances and regulations.
HIPAA
Full stack developers help to make healthcare apps secure and protect privacy of medical records under HIPAA compliance to safeguard patient information. HIPAA compliance guarantee patient’s right to have access over their medical records. HIPAA stands for Health Insurance Portability Accountability Act. If you are a Full-stack developer, you must be able to explain how you are going to add HIPAA compliance to your healthcare apps and how you will make it HIPAA compliant.
PCI DSS
PCI DSS is short for Payment Card Industry Data Security Standard, a suite of regulations that have to be met for maintaining compliance in applications that handle credit card details for the card schemes Visa, Discover, American Express and MasterCard. Consequently, it is obvious that a developer must be familiar with the PCI DSS requirements in order to make a payment app regulated.
FISMA
Federal Information Security Management Act (FISMA) is a compliance framework where a developer can concentrate on implementing computer and network security to support the US Federal Government and its contractors and affiliates. By working towards FISMA standard, the developer will improve security of software.
It is important to understand all the above skills and technologies to become a Full stack developer. LeewayHertz has a team of Full stack developer who can build a digital solution as per client requirements.
Where is Redux used?
State Wrangling in React Rodeos
- Imagine a wild herd of states in a React app, Redux lassos them for an easier roundup.
Time-Travelling Debug Delight
- With Redux, developers don the hat of a chrono-detective, stepping through state changes like a walk in the time park.
Consistent State Across Cosmic Components
- Developers use Redux to whisper sweet nothings to components, keeping their states in a harmonious dance across the cosmos.
Scaling Mount Performance
- When apps hit puberty and grow big, Redux pumps up their performance muscles, making them lean mean state-management machines.
Redux Alternatives
Context API
Built into React for state management, simplifying component-state sharing without 3rd-party libraries.
// Context creation
const MyContext = React.createContext(defaultValue);
// Context Provider
{/* Components */}
// Context Consumer
{value => /* render something based on the context value */}
- Integrated in React, no extra library needed.
- Ideal for small to medium-size apps.
- Simpler API compared to Redux.
- Lack of middleware support.
- Not as scalable for complex state management.
- Less dev tools compared to Redux.
MobX
Reactive state management solution leveraging observables for automatic updates of the UI responsive to state changes.
// Defining an observable state
const store = observable({
count: 0,
increment() {
this.count++
}
});
// Reacting to state changes
autorun(() => {
console.log(store.count);
});
// Triggering state changes
store.increment();
- Simple and effective for complex states.
- Automatic reactions to state changes.
- Less boilerplate code than Redux.
- Less predictable state mutations.
- Can be overkill for simple state management.
- Potential performance issues with large object trees.
Recoil
A state management library for React providing a more granular approach to state updates with atoms and selectors.
// Atom definition
const textState = atom({
key: 'textState', // unique ID
default: '', // default value
});
// Component using atom
function TextInput() {
const [text, setText] = useRecoilState(textState);
return (
setText(e.target.value)} />
);
}
- Granular control over state and re-rendering.
- Components can subscribe to only parts of the state.
- Built-in async queries support.
- Still in experimental phase.
- Smaller community and ecosystem.
- APIs may change, as it is not fully stable yet.
Quick Facts about Redux
Redux: The State Wrangler
Once upon a time in 2015, two JavaScript cowboys, Dan Abramov and Andrew Clark, corralled the chaos of state management into a harmonious library known as Redux. Inspired by Facebook's Flux and the functional fervor of Elm, they concocted a single source of truth that made state mutations in the web dev saloon predictable and trackable. Behold, the Redux revolution began!
The Immutable Time Machine
Redux brought a sherif-like order to the Wild West of states with its unchanging, or 'immutable', state containers. Every action was like a "Wanted" poster, telegraphing the wanted changes without a single tumbleweed of state being altered along the way. Time-travel debugging? Yep, that futuristic voodoo was baked right in, allowing developers to rewind and replay application states faster than a gunslinger could draw!
The Version Saga
Since its inception, Redux has been through a saga of versions, each more refined than the last. Beginning with its beta release faster than a jackrabbit, it sprinted past v1.0 in the same year of its birth. The community lassoed in with creative addons like Redux-Saga, and like a beloved folk hero, Redux has become an essential tale in the developer's lore, with its epic last stand at version 4.x.x as of my update, holding the fort with new features and fixes.
Here's a snippet of Redux in its natural habitat, taming a wild action in the vast plains of an app:
const ADD_TODO = 'ADD_TODO';
function addTodoAction(text) {
return {
type: ADD_TODO,
text
};
}

Top 10 Redux Related Tech
JavaScript
Imagine trying to dance without music; that's coding Redux without JavaScript. This programming language is the salsa sauce to your nachos, the foundation of all things Redux. Without it, you're just wiggling your fingers on a keyboard making magic spells.
const action = { type: 'DANCE', steps: 'salsa' };
React
React and Redux are like Batman and Robin, peanut butter and jelly, weekends and sleeping in. This library is essential for rendering dynamic UI with states managed beautifully by Redux. It's like having a genie to maintain your app's views while you focus on granting wishes.
import React from 'react';
import { useSelector } from 'react-redux';
const DanceMoves = () => {
const moves = useSelector((state) => state.moves);
return <div>{moves}</div>;
};
Redux Toolkit
Redux Toolkit is like your Swiss Army knife in the wilderness of state management. It packages simple patterns and best practices into one delightful bundle. RTK slices, dices, and makes managing Redux state as easy as pie (mmm, pie...).
import { configureStore } from '@reduxjs/toolkit';
import reducer from './reducer';
const store = configureStore({ reducer });
Redux DevTools Extension
Ever wanted to be a time traveler? Redux DevTools is the closest thing to a DeLorean in the Redux universe, allowing you to jump to different states faster than Marty McFly says "Great Scott!" It's a must-have for nipping bugs in their buggy buds.
import { composeWithDevTools } from 'redux-devtools-extension';
const store = createStore(reducer, composeWithDevTools());
Redux-Saga
Picture Redux-Saga as the orchestra conductor for the asynchronous symphony in your app. It makes async flows (like data fetching) as elegant as a tuxedo-clad Maestro waving a baton at a room full of musical prodigies.
import { call, put, takeEvery } from 'redux-saga/effects';
function* fetchUser(action) {
const user = yield call(Api.fetchUser, action.payload.userId);
yield put({ type: 'USER_FETCH_SUCCEEDED', user });
}
function* mySaga() {
yield takeEvery('USER_FETCH_REQUESTED', fetchUser);
}
Redux-Thunk
Need to kick back and dispatch actions with delayed gratification? Redux-Thunk is like that friend who tells you, "Chill, I got this," and then actually does. It's middleware that allows you to write action creators that return a function instead of an action.
const fetchUser = (userId) => {
return (dispatch) => {
dispatch({ type: 'USER_FETCH_STARTED' });
fetchUserById(userId).then(user =>
dispatch({ type: 'USER_FETCH_SUCCEEDED', user })
);
};
};
Reselect
Imagine having a personal assistant who remembers all your preferences. That's Reselect in the Redux world. It’s a selector library for Redux, optimizing state computation and giving your components what they need without breaking a sweat.
import { createSelector } from 'reselect';
const getMoves = state => state.moves;
const getRhythm = createSelector(
getMoves,
moves => moves.filter(move => move.isRhythmic)
);
Immutable.js
With Immutable.js, your state's untouchability rivals that of King Tut's tomb. It helps keep your state read-only, leading to fewer bugs and a happier coding life (And fewer curses than King Tut's visitors).
import { Map } from 'immutable';
const initialState = Map({ isDancing: false });
function danceReducer(state = initialState, action) {
switch (action.type) {
case 'START_DANCING':
return state.set('isDancing', true);
default:
return state;
}
}
Typescript
Ever wanted a bouncer at the door of your code checking types like IDs? Enter TypeScript—the strongly typed bouncer for JavaScript. It adds a layer of type safety, reducing runtime errors and making refactors less scary than clowns at a birthday party.
interface DanceState {
isDancing: boolean;
}
type DanceAction = { type: 'START_DANCING'; };
const danceReducer: Reducer<DanceState, DanceAction> = (state = { isDancing: false }, action) => {
// reducer logic
};
Webpack/Babel
Webpack bundles your assets like a financial advisor consolidates your investments. Pair it with Babel, the translator who turns your modern JavaScript into something even Internet Explorer can understand (almost a miracle worker).
module.exports = {
entry: './src/index.js',
output: {
path: __dirname + '/dist',
filename: 'bundle.js'
},
module: {
rules: [{ test: /\.js$/, exclude: /node_modules/, loader: 'babel-loader' }]
}
};
