How statistics are calculated
We count how many offers each candidate received and for what salary. For example, if a iOS with Firebase 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.

Quick Facts about Firebase
Firebase: A Dev's Swiss Army Knife Since 2011!
Imagine a world where setting up a backend is as simple as microwaving popcorn. That's Firebase for ya! Created by a couple of clever humans named James Tamplin and Andrew Lee in 2011, it was made for developers to build web and mobile apps without the server-side hustle. Google couldn't resist its charm, so they adopted it in 2014. Firebase started like a cute baby real-time database but has grown into a full-grown platform with muscles like authentication, hosting, and even machine learning. It's like watching your little code grow up!
Realtime Database vs. Firestore: Dawn of Data
Once upon a time, Firebase offered a Realtime Database that was all about delivering live data across devices lickety-split. But then in 2017, a new challenger approached: Firestore! With superpowers like indexing, querying, and offline support, Firestore swooped in, promising better scalability for the data-hungry apps of tomorrow. Devs were faced with the ultimate choice: stick to the OG Realtime Database, or level up with Firestore. Epic!
Version 9 and the Modular Web SDK
Step aside, every other SDK, Firebase Version 9 entered the chat in 2021, and it was all about being nimble on its feet. This version brought a modular approach, meaning you could pick and mix the bits you need, like a techy version of candy shopping. This made web bundles lighter than ever, as if they went on a code diet, and load times got faster than a cheetah on a skateboard. Check out the sleek import:
import { initializeApp } from 'firebase/app';
import { getFirestore } from 'firebase/firestore';

Top 10 Firebase Related Tech
JavaScript: The Chatty Scripter
Imagine a party where everyone is silent—quite the snooze fest, right? That's a dev party without JavaScript, the life of the Firebase fiesta! This ubiquitous language is the backbone of web and mobile app development. It's like the Swiss army knife that can chat with Firebase as smoothly as a charming diplomat.
// Here’s a little snippet of JS talking Firebase
firebase.database().ref('/path/to/resource').on('value', (snapshot) => {
console.log("Got some fresh data!", snapshot.val());
});Node.js: The Backend Beast
Cue the dramatic entrance music—Node.js makes server-side scripting sexy again! This runtime lets you use JavaScript to write server code, and when paired with Firebase, it's like peanut butter and jelly: a match made in heaven for building scalable, real-time apps.
// Node.js + Firebase = Party Time
const admin = require('firebase-admin');
admin.initializeApp();
// Let's get this server-side party started!React: The UI Magician
Need a dazzling user interface? React's got you. Picture a magician pulling rabbits out of hats—that’s React conjuring up UI components. Combine it with Firebase, and you've got an app that's as responsive as a cat on a hot tin roof.
// Summon a React component with Firebase
class CharmingComponent extends React.Component {
componentDidMount() {
this.magicListener = firebase.firestore()
.collection('spells')
.onSnapshot(this.onSpellUpdate);
}
// ...
}Android Studio: The Android Alchemist
It's time to transmute ideas into gold on Android! Android Studio is the philosopher's stone for app developers, turning basic code into treasured apps. Crafting Firebase-backed Android apps is like potion-making—mix the right ingredients, and poof! Instant hit on the Play Store.
// Alchemy in action: Android + Firebase
FirebaseDatabase.getInstance().getReference("alchemy").setValue("gold");iOS Development: The Apple Whisperer
Do you hear that? It's the sweet whisper of Swift and Objective-C calling the shots in the orchard of iOS devices. Developing for iOS with Firebase is like knowing the secret language of Apple trees—you ask, they deliver juicy apps.
// Whispering sweet nothings to Firebase
let ref = Database.database().reference(withPath: "whispers")
ref.observeSingleEvent(of: .value, with: { snapshot in
// Listen to the rustling leaves (data)
})Flutter: The Cross-Platform Conjuror
Flutter waves its magic wand, and voilà! Your single codebase morphs into apps for iOS and Android. This SDK is the cross-platform wizard, and once it joins forces with Firebase, the spell is complete—universal apps that run like a dream.
// Flutter utters a spell for Firebase Firestore
Firestore.instance.collection('incantations').snapshots().listen((data) {
// Magic happens here!
});REST APIs: The Diplomatic Courier
REST APIs are the tireless postal workers of the internet, delivering JSON packages between Firebase and your app. These messengers ensure that regardless of your tech stack, the Firebase data reaches its destination safe and sound.
// Send a POST request to Firebase
fetch('https://your-firebase-app.firebaseio.com/messages.json', {
method: 'POST',
body: JSON.stringify({ text: "Hello Firebase!" })
})Google Cloud Functions: The Cloud Conjurer
Google Cloud Functions is like a reclusive wizard that emerges only when an event in your Firebase kingdom occurs. It weaves spells of logic in the cloud, reacting to authentication, database changes, and more, without you needing to maintain a server.
// A simple Google Cloud Function charm
exports.magicOnWrite = functions.firestore
.document('wands/{wandId}')
.onWrite((change, context) => {
// Magical cloud things happen here
});Authentication Services: The Bouncer
Authentication services are the burly bouncers of app security, checking IDs at the Firebase door. They work tirelessly, ensuring that only legitimate users can enter and mingle at the exclusive data party happening inside your app.
// Authenticate with Firebase using Google SignIn
firebase.auth().signInWithPopup(provider).then(function(result) {
// Credential check passed, welcome to the VIP section!
});Redux: The State Sorcerer
In a land of fickle UI states, Redux stands as the grand sorcerer, maintaining order in the chaos. When used with Firebase, it ensures that your app state doesn't turn into a pumpkin at midnight by keeping it predictable, so go ahead, keep that ball rolling!
// Spellbinding Redux with Firebase
store.dispatch({
type: 'CAST_SPELL',
payload: firebase.database().ref('spells').once('value')
});
