How to Become a Backend Developer in 2023
Do you know that, on average, a Backend developer in US makes $133,000 yearly? It is one of the highest-paying developer roles in the world. Maybe you are in for the passion. Maybe your passion is the $ itself, or maybe you are bored and just want to learn something new.Irrespective of your cause, this blog introduces Backend development and guides you on how to become a Backend developer.
#Step 1: What is Backend Development?
Knowing what duties fall under "How to become a Backend Developer" is a major confusion for newcomers. Also, how does it vary from Frontend Development?Let’s address the query.When you visit a website, everything you see and interact with is part of Frontend development also referred to as client-side or browser-side development. It covers how the content is present on the website, including minor user interfaces elements like menus, dropdowns, transitions, and models.On the other hand, Backend Development deals with code that runs on the server. It is all the behind-the-scenes stuff that happens on the servers that the user never sees and focuses on securing and managing the data. The quality of the user experiences a website provides depends on Backend programming.For example, a Backend developer would write the code that interacts with the database to get a list of images, and the Frontend dev. would write the code that displays the photos in a gallery with a slideshow.Handling Website design, building templates, CSS, HTML, javascript, etc., are generally considered Frontend. Working with Databases, APIs, web development, PHP, and related languages are all considered Back end.
#Step 2: Understanding the Roles and Responsibilities of a Backend Developer
With Backend, Power comes responsibilities. Let’s look at some of the roles and responsibilities of a Backend Developer:
- Supporting existing Backend.
- Creating and maintaining web applications with clean codes.
- Working with Frontend Developers to define goals and integrate user-facing aspects with server-side logic.
- Developing and Maintaining APIs.
- Management of hosting environments.
- QA testing.
- Troubleshooting and fixing bugs.
- Development of site architecture using appropriate methodologies.
#Step 3: Learning Backend Development
Everyone starts somewhere, don’t worry if you’ve never coded before. Here is a roadmap on how you can become a Backend Developer.Here are the steps you will need to follow:
- Learning the fundamentals of the Web
Understanding the fundamentals of the Web is essential. Get familiar with HTTP, DNS, Browsers, Domain, Hosting, etc., and understand how they work.
- Basic Frontend Development
It’s important to know how Frontend development works. Knowing even the basics can help ease your process of mastering and understanding Backend development.You can start by learning CSS and HTML.
- Learning a Programming Language
Knowing how to code is essential for a Backend developer. Choose a programming language and learn the fundamentals of programming language:
- Variables
- Functions objects
- Data types
- Core principles of OOPS
- Execution.
Some Popular Programming Languages for Backend Development are JavaScript, PHP, Python, Ruby, and C#.
#Step 4: Learning a Backend Framework
A framework is a well-organized collection of tools and libraries that assist you in accomplishing tasks in a specified manner, sometimes with less code.For example, if you’ve built websites with PHP and MySQL, you’ve probably worked with SQL queries to retrieve data from a database. You can use frameworks to query databases without having to write SQL queries. So, learning a framework will help you develop Backend applications faster.There are several Frameworks available. You can choose a framework depending on the programming language.Some popular Backend frameworks are Node.js, Django, Ruby on Rails, ASP.NET, and Laravel.
#Step 5: Databases
A database is a system for classifying and storing data.There are two types of Databases.SQL - SQL databases store the data in tables.SQL databases: MySQL, PostgreSQL, SQLite.NoSQL - NoSQL databases store data in a document.NoSQL databases: MongoDB, CouchDB, DynamoDB.Developers like to argue about SQL and NoSql and which is better, but it’s like arguing about Coke and Pepsi. They’re both good for different reasons, and in many cases, either will do.
#Step 6: APIs
Application Programming Interface. It allows you to access the data from another application and is a way for applications to communicate with each other.A Backend with API helps developers to interact with Backend services and applications, which helps them improve the user experience on the website. Some of the APIs to learn are: REST, JSON, AES, GSON, SOAP, XML-RPC.
#Step 7: Advanced Topics
Once you understand the programming language, frameworks, databases, and APIs, you get a good understanding. You will come to advanced topics like Hashing, Caching, Web Security, Web servers, Rate Limiting, Backend Testing, etc. Learning never stops. And it should never stop. Learning is a continuous process, especially in web development.
Level Up
After you’ve finished all these steps, it’s time for practice. Being a good developer takes time; getting used to languages, frameworks, concepts, etc., doesn’t happen overnight.Learn by doing. Start developing projects on your own. Nothing will improve you as a developer than building a project from scratch.
Get a Job
Get a Job or an internship. Depending on your command, that can be an entry-level job or an advanced position. You will gain experience on real projects backed by an organization which is ideal for a new learner.
There you go. You are a Backend Developer now.
Soon you will have the confidence and proficiency with Backend development. Now depending on your goals, you can become a freelancer. Or build personal projects. Or continue working for an organization. We wish you all the luck!

What is Concurrency and Parallelism in Python
Suppose you are familiar with coding in the Python programming language. In that case, there must have been many instances where you just wanted to speed up the entire process by executing multiple tasks at once or by interleaving numerous tasks. Both approaches are possible in Python and are known as Concurrency and Parallelism.There are two extents to which you can speed up your processes – I/O and CPU Consumption. If your code involves a lot of files accessing and similar repetitive tasks, it is I/O bound. On the other hand, if your code includes a lot of heavy computations, it is indeed CPU bound.Both types of tasks differ in terms of the resources they require. When an I/O bound code is running, it is not using the CPU’s core that much because it is sitting idle waiting for the responses to be received. We cannot improve this process by adding more computational power. The reverse is the same for CPU-bound code.To remove either of the bottlenecks, we use two mechanisms, i.e., Concurrency & Parallelism.
Concurrency v/s Parallelism
Concurrency means doing multiple things at once. However, Concurrency takes up a slightly different approach in python programming. Concurrency in Python is managing alternate jobs at the same time. It means that the python runtime executes not all jobs or tasks at once; instead, they alternate to achieve optimum efficiency. Concurrency involves multiple tasks taking turns accessing the shared resources.While, on the other hand, Parallelism does mean that multiple jobs or tasks are executed simultaneously by the python runtime. In Parallelism execution, several tasks are allowed to run side-by-side on independently partitioned resources.Concurrency and Parallelism both have different aims and solutions that they bring to the table. Concurrency’s goal is to prevent various tasks from blocking by switching among them while waiting on an external resource. To achieve Concurrency, the Python runtime completes multiple network requests.Usually, when the user launches one request, it takes time to finish, which is the waiting period, and then the next one is launched. A concurrent way of doing this is to launch all requests simultaneously and switch among them as we get the responses.Contrastingly, Parallelism maximizes the hardware used. For example, if you have eight cores in your CPU, you do not want to maximize on one while the other seven cores sit idle; you would like to launch processes that utilize all eight cores at once.
Implementing Concurrency & Parallelism in Python
Python permits the usage of both Concurrency and Parallelism with its syntaxes and uses cases. In Python, Concurrency is implemented by threading and coroutines, or async. And Parallelism by Multiprocessing.Let’s have a look at the advantages and disadvantages of all three methods:
Python Threading
Threading helps you create multiple threads across which you can distribute I/O bound workload. One noteworthy thing about threading is that it does not work the same way it works in other programming languages like Java. For example, Java’s Global Interpreter Lock (GIL) ensures that only one thread is in processing at a time and memory usage is thread-safe.Advantages of Python ThreadsThreads in Python are a convenient and well-understood way of running tasks that waits on other resources. Apart from this, Python’s standard libraries have high-level conveniences for running operations in threads.Disadvantages of Python ThreadsPython threads are cooperative, which means that the Python runtime divides its attention between them. As a result, Threads are not suitable for a task that is CPU intensive because if we run a CPU intensive task in threads, the runtime will pause it while switching to a different thread so, there is no performance benefit overrunning that task outside of the thread.Another disadvantage of using threads in Python is that the developer needs to manage the state between them. We must manually synchronize different threads to expect the desired results, an overly complex task.
Python coroutines, or async
Coroutines or async is an alternate method of running tasks simultaneously in Python. Instead of using multiple threads, coroutines use special programming constructs and all the tasks run on a single thread.Advantages of Python coroutinesWith Coroutines, you can quickly tell which programs are running side by side by looking at the syntax. With threads, this is not possible; any function might be running in a thread.Another advantage of Coroutines is that they are free from architectural limitations faced by threads. Switching between many coroutines in a program is easy and requires less memory than threads.Disadvantages of Python coroutineWriting code for Python coroutines is a little complex as it requires the programmer to write it in its distinct syntax, making its mingling impossible with synchronous code design-wise. Using coroutines can be a little tricky for programmers who are not used to writing their code asynchronously. Also, you cannot run CPU-intensive tasks side by side efficiently.
Python Multiprocessing
Multiprocessing in Python allows us to run numerous CPU-intensive tasks simultaneously by launching multiple, independent copies of Python runtime. Multiprocessing leverages each core in your CPU by creating a python interpreter for each process.Advantages of Python MultiprocessingMultiprocessing is better than async or threading because it sidelines their limitation of the python runtime forcing all the operations to run serially by giving each process a separate python runtime and an entire CPU core.Disadvantages of Python MultiprocessingThe first downside of Python Multiprocessing is the additional overhead associated with creating the processes. Another downside is that each subprocess requires a copy of data sent from the primary process.
Best Method to use
If you are dealing with long-running, CPU-intensive operations, use multiprocessing. If you are dealing with long-running, CPU-intensive operations, use multiprocessing.On the other hand, if you perform functions that do not involve CPU but wait on external resources, use threading or async. Async is favorable to threads for long-running IO operations. And, if your IO-bound operations are fast, go with multi-threading.As of today, Python programming language is the most preferred language for Artificial Intelligence, Robotics, Web Development, and DevOps.Hope you found this blog useful. Cheers and good luck with your future.

How to Prepare for a Full Stack Developer Interview in 2023
In full-stack technologies, technical interviews are the final barrier for most full-stack software developers before accepting a job offer. Each stage of the hiring process serves a specific purpose: phone screens determine general fit. Interpersonal skills are assessed through behavioral interviews. A full-stack developer interview assesses how well your programming talents meet the firm's needs and the post's duties.Fortunately, things have altered dramatically in recent years. Instead of the old-school Google brain puzzles (such as “How many golf balls could fit in this room? “), You’re more likely to get a take-home assignment or have a collaborative conversation if you whiteboard “Hello, World!” in 10 languages. These are assessments that more closely mimic the kind of work you’d be doing if hired in your full-stack developer interview round.Interviewers are rooting for you to succeed. Hiring you allows them to return to their real occupations, the organization becomes more productive, and everyone benefits financially and professionally.
Get the valuable basics right for the interview
Interviews are about demonstrating what you can do, rather than telling someone what you can accomplish.
Step #1: Be prepared for the Interview
The plan should be the same no matter what your interviewer asks you; understand the problem, design a solution, explain it, and implement it. To put it another way, being a good engineer is the greatest way to prepare for your interview.That isn’t to say you shouldn’t prepare for a technical interview with some homework. Begin by looking through the company’s stack. If it’s a Ruby shop, you should be familiar with the language. Use StackShare and any company-owned public GitHub repositories to determine what languages and libraries they use.
Step #2: Be Presentable
Dress comfortably and professionally whether you attend the office or video chat in from home. If your shoes are too tight or you’re concerned about a sloppy collar, you won’t be able to think clearly.Once you’ve started, remember that if you freeze up, make a mistake, or don’t know an answer, you can just be honest and admit it. Don’t be concerned about wasting time or seeming stupid. If you need a moment to think, take it and then rejoin the conversation.Discuss the issue with your interviewer, ask questions, and reconsider your strategy. This is similar to showing your work on a test for half credit, and it can help you out.
How to Prepare for (and Ace) 4 Types of Technical Challenges
Not every full-stack developer interview is conducted in person. Some of these don’t even require coding. It all depends on the business and the position.Each of the four types of examinations analyses various skills you’ll need on the job, so you’ll need to approach and prepare for each one separately.1. Exercise in Live CodingThe classic technical interview looks like this: Within 30 or 40 minutes, you will have written working code.If you’re given some faulty code, for example, you’ll need to find the bug, fix it, pass the test suite, and then explain what you did. You’ll most likely be requested to modify something minor in this type of technique, which is popular among Test-Driven Development (TDD) teams. It’s basically a duo programming activity. Your interviewer may be present in the room with you or participate by video chat from afar. You’re unlikely to have access to your ideal development environment, which adds to the stress. You could have to work with a limited Integrated Development Environment (IDE) or a strange laptop.Even if you can’t fix the bug, your method is important. When you’re stuck, ask questions and explain your strategy to the interviewer.2. Homework AssignmentTake-home tests provide all of the advantages of the real world, including access to Google, Stack Overflow, and your own computer, while still assessing your programming abilities. You prepare for them in the same way that you would for live coding, but you’ll deliver your work in a different way.For instance, you might be requested to read a brief product specification and develop a Sudoku validator with a test suite. You’ll organize a meeting to present your work after you’ve submitted your code. Validating Sudoku boards isn’t tough, but how you do it reveals a lot about how you think about problems, follow directions, and interpret criteria.Companies usually give you a set amount of time to complete your take-home assignment, whether it’s a deadline (present your code within three or four days) or a time limit (complete the task in no more than 4 hours). Give yourself time to evaluate and modify your work in either situation, just as you would if you were writing a critical report or sending a private email.Remember that there is no “correct” method to solve a problem, however, the interviewer may be interested in your knowledge of specific ideas and will likely inquire about them throughout the interview.3. Design ProblemPractical exams include live coding and take-home tasks, but theoretical tests are also popular. That’s where having a whiteboard comes in handy.You’ll be given some broad boundary conditions (for example, make it web-based and text-only) and an initial prompt, such as “What kinds of data will you need to manage and how would you model it?” You’ll have to design something—perhaps a messaging application—and you’ll be given some broad boundary conditions (for example, make it web-based and text-only Your interviewer may gradually broaden the scope of your questions, asking you to consider the interface, networking, and refactoring as you progress from a simple notion to a full-fledged software, based on your responses.4. Trivia ContestIt doesn’t matter if you have 10 months or 10 years of experience at some companies—all it’s about is the fundamentals. And nothing is more fundamental than computer science knowledge.“What is bigO notation and why does it matter?” can be a conceptual inquiry. or “How would you recursively implement this program?” for inquiries regarding a particular language I’d recommend brushing up on the current ECMAScript release features and browser oddities if you’re interviewing for a job writing JavaScript, for example.Smaller businesses, where the tech stack is limited and new workers must hit the ground running, are the most likely to have language-specific queries. This can be difficult if you’re new to the language, but as Juan Müller, lead engineer at Greenhouse, points out, “what interviewers are looking for is your ability to reason about code, even if you’re not prolific in the language in which you’re being tested.” Most languages will use similar constructs, and logic will remain constant.”
Conclusion
If you have more experience, your full-stack developer interview will have a slightly different purpose. Employers will look at how adaptable you are, how current your abilities are, and how well you fit in with the team.Although uncomfortable, a brief technical interview—in whatever shape it takes—can spare you and your employer months of frustration due to misaligned expectations. So figure out what kind of obstacle you’re up against, do your homework, go in confidently, use what you’ve studied and prepared for, and leave knowing you gave it you’re all!
