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 Java 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.

Quick Facts about Java
Java: A Cup o' Joe That Revolutionized Code
Once upon a time in 1995, a quirky language sprung out of Sun Microsystems' brain trust. Helmed by James Gosling, Java's dad, the language aimed to be the 'write once, run anywhere' poster child. With its platform-independent JVM (Java Virtual Machine), it quite literally broke the mould, turning into every developer's go-to for cross-platform shenanigans. Celebrated for its OOP (Object-Oriented Programming) purity, it's like LEGOs for grown-ups, letting devs construct and manipulate their object world.
Generics: Java's Gift to Typecasters Everywhere
Fast forward to 2004, Java 5.0 brought Generics to the party. Why care? Well, picture this: you've got a collection of rubber ducks, and you only want rubber ducks, no bath plugs or boats. Generics let you specify that – "This collection is solely for ducks!", preventing coding faux pas and keeping your bath time blissfully on-brand.
ListmyDucks = new ArrayList ();
myDucks.add(new Duck("Howard"));
// Compile-time error on the next line - no unwelcome guests in the duck pond!
myDucks.add(new BathPlug());
Java and the Android Takeover
In 2008, a green robot took over our pockets, and guess what it was stuffed with? Java! Android apps thrived on Java code, injecting Java's tendrils further into tech's fabric. Who knew that coffee-inspired bytes would empower everyone to chalk up high scores in mobile games while waiting for their actual coffee?
