Scala is known as a powerful programming language that amalgamates object-oriented and functional programming paradigms. It is regarded for its high scalability as well as expressive syntax. It is used on a large scale to handle complex software projects.
Therefore, more companies are adopting Scala and hunting for skilled developers. Finding the right Scala developer has become quite important. The fact cannot be ignored that it has turned out to be a challenge because of the specialized nature of the language.
The content outlines the excellent qualities to look for when you are on your way to hire scala developers. These qualities help you to find the ideal candidate for your office.
Proficiency In Scala And Its Ecosystem
You must check out if they have a deep understanding of the Scala language. The syntax is quite complex in comparison to languages such as Java or Python. Developers need to have excellent coding and problem-solving skills. Moreover, developers must be good at functional programming and object-oriented programming as Scala supports both paradigms.
What About The Key Skills
It needs to have excellent proficiency in object-oriented programming and functional programming.
- It requires a deep understanding of the Scala standard library.
- They should also have experience with collections and error handling in Scala.
- They should have deep knowledge of Scala frameworks such as Play or Spark.
Important Tip
The most important thing is that a great scala developer must be comfortable with tools. They should also be informed about the prominent libraries within the Scala ecosystem.
Having Experience With Java and JVM
Scala works on the Java Virtual Machine. Moreover, many organizations use Scala in conjunction with Java. This means it is familiar with the JVM and quite essential. A professional Scala developer must have a strong background in Java development. It plays a huge role in helping them understand JVM internals. They also get help to optimize Scala code for the platform.
Holding knowledge of JVM is quite important. They should also be aware of memory management as well as garbage collection. It is quite important when they develop applications that need high performance.
What Makes It Important
Knowing Java and JVM is important since a variety of Scala projects are integrated with existing Java systems. They need to know Java to have a smoother transition between the prominent two languages. A deep understanding of JVM helps to optimize the entire application’s efficiency.
Understanding Of Concurrency and Parallelism
Scala holds excellent strength to handle concurrency and parallelism with ease. Akka is known for being a popular framework built for Scala. It allows developers to create highly scalable as well as distributed systems. Hire Scala developers are quite important to ensure they understand how to write as well as manage concurrent applications intelligently.
It is important to be proficient in the context of tackling concurrent operations. They must be good at working with threads. The most important thing is that managing distributed systems makes them different from others. Professionals should have an understanding of the Actor model on which Akka is based. It makes them good at handling projects that need high availability and fault tolerance.
What About The Areas Of Expertise
- Knowing multi-threading as well as asynchronous programming is important.
- They should have experience with Akka, Akka-oriented streams, and other familiar frameworks.
- They must be good at how the actor model works and how it helps with concurrency.
Holding Familiarity With Big Data Technologies
Scala has turned out to be synonymous with big data. It happens because of its close integration with Apache Spark. We all know it is a powerful big data processing framework indeed. There are a variety of organizations that pick Scala for their huge data projects.
The reason is that it is good at performance and expressiveness. While hiring Scala developers, it is quite important to assess their experience following big data technologies. It also holds the ability to work with huge datasets.
Do you have a big data-oriented project? The developer must be comfortable with using Spark with Scala. They should also be well-versed in data processing and data pipelines.
What About The Relevant Technologies
- They should know Apache Spark and Hadoop
- Professionals should be good at building and managing data pipelines
- Experts must be good at handling large-scale distributed systems
Problem Solving and Analytical Thinking
Scala developers generally have to solve complex problems. These issues are associated with scalability and system architecture. And that is why it is quite important to have problem-solving skills. They should be good at breaking down issues into manageable parts. It helps them to figure out the effective solutions. And it is one of the key traits of a successful Scala developer.
Moreover, analytical thinking plays a huge role in creating efficient systems. Developers must be good at analyzing issues from different angles. They should apply excellent practices of functional programming and understand when it needs to align with object-oriented concepts.
What You Need To Hunt For
- Find out what sort of aptitude they have to tackle complex coding challenges.
- What is all about the ability to design scalable as well as efficient systems
- Do they have strong analytical and logical thinking abilities? If yes, they are worthy to choose.
Holding Knowledge Of Microservices Architecture
There is no doubt that Microservices are gaining popularity. It happens because of their scalability and flexibility. It helps to improve software maintenance. Moreover, Scala comes up with its frameworks such as Akka and Play. They play a huge role in building Microservices architectures.
You must hire scala developers who understand this sort of architectural style. They should also be aware of building and deploying microservices-oriented applications.
What Skills Need To Assess
- They must have experience in designing. Building Microservices using Scala frameworks can do wonders for you.
- It is important to hold an understanding of Restful services. An understanding of API development also adds more value to it.
- Professionals should also be aware of containerization tools such as Docker and orchestration platforms such as Kubernetes.
Test-Driven Development Expertise
We are living in a modern era. Ensuring code quality is quite important in today’s software development. Test-driven development has truly turned out to be a widely adopted practice to ensure that code is completely reliable and bug-free.
A good Scala developer must have experience in TDD. They should be aware of unit testing and integration testing. Professionals should have a robust testing approach. They should ensure that the code aligns with the project’s quality standards.
What About The Key Testing Frameworks
- For testing Scala applications, ScalaTest or Specs2 are good to go ahead with.
- It is important to have knowledge of mock objects and testing with Akka/Play. Proficient knowledge makes things easy in an incredible way.
- Holding proficiency in continuous integration/CI/CD pipelines
Summary
Hiring an ideal Scala developer loaded with the right blend of technical and soft skills can truly take your project to the next level. Professionals know how to solve issues quickly and ensure effective communication. So, what are you waiting for? It is time to hire the best developer to lift the value of your business.
