How To Hire Elixir developers?

Elixir is a general-purpose programming language developed by José Valim in 2011 to address two main goals: allowing developers to design and manage large-scale projects while maintaining scalability and increasing productivity. Elixir inherits all of Erlang's advantages, which include being a dynamically typed, concurrent, functional general-purpose programming language that is one of the finest for constructing real-time systems.

Codementor is a platform that allows you to connect with an expert developer for live mentoring on your projects, but it is much more. As a client, you'll get access to some of the most talented Elixir developers on the planet. In addition to Elixir, Codementor provides competent mentors and freelance developers for projects using a variety of technologies, including web, data science, mobile, and more.

Why Do You Need To Hire an Elixir Developer?

Companies are actively trying to employ Elixir developers right now since the language has grown in popularity over the last few years. The quantity of intuitive features and functionalities is one of the reasons why it is one of the go-to languages for developers.

Elixir was created to combine the best of Ruby, Erlang, and Clojure into a single platform, and it succeeded. Elixir has several advantages that make it an appealing programming language to use, some of which are listed below:

Elixir's scalability is one of its main advantages, as it allows you to scale your programs as your organization grows while also making the maintenance process easier for developers. Another advantageous feature of Elixir is that it is quite simple to iterate, allowing you to spend less time coding and more time developing your concept. Elixir also supports concurrency. , allowing you to run thousands of processes at once without experiencing any delays.

Skills Required For an Elixir Developer

1) A sense of scale and concurrency

What is concurrency, exactly? Consider computing to be a race in which the winner is determined by the completion of the course by all competitors. The runners (processes) are usually bound together with a rope so that if one fails, the others are unable to continue any further. What if you untie the racers and let them finish in whichever order they want, regardless of the result?

Concurrency isn't normally the first or third thing new developers learn, but Elixir developers should start learning about it as soon as possible. Elixir has a variety of uses, but when you need to accomplish a lot of things at once, it's where the magic happens. Unlike the more connected ways other systems function, Elixir may scan through multiple processes flopping at the same time, with dozens more running in the background.

Without this linkage, an Elixir system can have self-healing properties, and its processes are small enough to execute on all CPUs at the same time. In this way, Elixir is similar to its father, Erlang, which is characterized by the phrase "write once, run forever." They both use a concurrency mechanism that is much distinct from traditional threading.

2) HTTPS and server-related issues

Web apps will be a big part of your Elixir work in the future. As a result, it will be governed, at least in part, by the HTTP protocol and server infrastructure.

Elixir comes with a slew of excellent web frameworks, like Phoenix and Absinthe, to mention a few. However, you won't be able to accomplish anything with them unless you have a fundamental understanding of how the internet works.

To begin, I would suggest a few things. To begin, familiarise yourself with the basic request-response communication cycle, which is well-explained here. Not only should you be aware of HTTP status codes, but also what to do if they occur. The distinction between POST and PUT methods is useful, and there is an excellent explainer thread over there.

Learn about DevOps practices and philosophy if you have most of the above covered and want to make a case for future promotions. You may find beginner-level training on YouTube, as well as dozens of free or low-cost courses on Udemy or Coursera. This will be useful for both Elixir and server work.

3) Databases

If you have trouble with databases in your prior technology, don't fret; Elixir will make things easier for you. Elixir will not toss many logs beneath your legs during the learning process if you have no relevant experience.

Don't get too excited just yet - Elixir isn't for individuals who want everything right away, as I'll explain in the last point of this list. A standard Ruby deployment will take care of several things for you when it comes to databases, such as creating and seeding the initial database. However, with Elixir, you are responsible for some of it.

After the initial stumbling block, Elixir performs admirably. Ecto, the database wrapper, supports both SQL and NoSQL databases. It's even more than that because it's a language-aware question.

Because you'll be spending a lot of time developing apps with PostgreSQL or other SQL databases for data storage in your project, knowing how Elixir works with them will come in handy during the interview.

4) Data processing in the style of a pipeline

Because Elixir is a functional language, it encourages data processing in the form of pipelines, which are made up of functions that modify immutable data structures. You will feel at ease if this method of data processing appeals to you. As you gain experience, libraries like GenStage or Flow will let you implement Elixir in a distributed context, which is one of Elixir's key advantages.

On this topic, there are several interesting case studies and workshops to listen to and watch. Try listening to ElixirConf recordings or watching this brief lecture for a reliable source.

5)Become an expert tinker

What exactly is a tinker? In other words, it's a person who, upon encountering an unknown button or dial, will press it just for the pleasure of pressing it. A person who is eager to learn more about a subject and is relentless in seeking out solutions, even if none are currently available.

The whole point of Elixir is that it has a robust core that needs to be reinforced by libraries that provide the "extra" features. This was done to keep processes light and speedy while reducing bloat. This idea extends to the library's creators as well.

So, when you're looking for a highly particular library for a niche task, this isn't Java or Ruby, where a quick search on GitHub yields 20 potential answers. Prepare to write stuff on your own in some circumstances. Elixir is incredibly extensible. BEAM VM's core and underlying power are intended to be suitable for a wide range of use scenarios.

6) Make Elixir-based projects

Alchemist Camp is a free resource for follow-along projects using Elixir whenever you're ready to start using Elixir to create projects. After you've gotten comfortable with those kinds of instructions, you'll want to go out and create your project. Unfortunately, when compared to tackling a problem from the beginning, follow-along tutorials can only teach you so much.

Find Hackathons, if any are available, to gain experience cooperating with a team of developers. Hackathons are events where people in the IT industry come together to "hack" a product in a short period, usually 24–48 hours. Working in a group will teach you things that you wouldn't have learned if you were working alone.
