What is Scala and who is a Scala Developer
The word Scala has been derived from Scalable Language. It is a general programming language used for many functions including web development and processing of data. Scala has qualities of both functional programming (FP) and object-oriented programming (OOP). OOP refers to a programming model based on the idea of objects. Objects hold both code and data. Functional programming involves building programs using mathematical functions.
A Scala developer is someone who can design, create and maintain applications based on Scala. Big data engineers, data scientists and application developers use Scala. Also, the language is used by many big companies because it is scalable.
How to Hire Scala Developer
There are many steps involved in hiring Scala developer for your team. One of them is to list out the company’s requirements. The next step is to take a look at their technical skills such as knowledge of Scala development. Also, look at the experience of the Scala developer before you hire.
Aspects to Consider Before You Hire Scala Developer
One of the first things to consider before you hire Scala developer is the scope of the project.
You could hire Scala developer to develop applications for small businesses. Or you could hire Scala developer to work on a large project where you need scalability. You could use Scala to speed up development and enter the market quickly to gain a competitive edge. Hire Scala developer depending on your needs.
Understand how Scala is used in businesses and industries. For instance, Scala may be used for deploying microservices. Microservices are tiny applications where each service works independently. Although every service may operate its process on its own, these services communicate with each other and clients. Microservices are used in a variety of industries, from entertainment to payment platforms or apps. Knowledge of the target audience helps both the Scala developer and the business.
The recruiter and the developer need to be aware of development trends. Here are some examples:
- Cloud computing is being adapted by most businesses. As developers use cloud platforms, Scala has come to be their preferred language to interact with the cloud system.
- Artificial intelligence (AI) is another hot trend in web and app development. Scala offers the right libraries and tools to ease artificial intelligence development.
- Machine learning (ML) is a kind of AI wherein apps are able to predict an outcome with the help of historical data. Scala, because of its functional programming quality, is used widely in machine learning.
Skills to Consider When You Hire Top Scala Developer
Hire top Scala developer with a combination of technical and soft skills, apart from experience. When you hire top Scala developer, consider these skills:
Hire a candidate with knowledge of Scala libraries and frameworks such as Play, Scalatra and Cats, among others.
Also, knowledge of testing tools that Scala offers including Specs2 and Scala Test helps. Developers can test both Java and Scala code with these tools.
Familiarity with Java Virtual Machine (JVM), which helps systems run a Java program is useful. Knowledge of JVM is important as Scala is built on it.
Hire a professional with skills in other programming languages like Java and Python.
Check if the developer has knowledge of structured query language (SQL) databases like MySQL. SQL is a set of tables which stores specific data sets.
Further, experience in building application programming interfaces (APIs) help. APIs enable applications to interact with each other. Developers can build APIs with Scala.
Apart from these, check the communication skills and presentation abilities of the potential Scala developer.
Steps to Hire Scala Developer
- Assess the resume of the candidate.
- Check for skills by asking questions about Scala development.
- Find out about work experience of the developer.
- Check if the candidate has any Scala certifications. This helps you understand the candidate’s level of expertise in the language.
How to Identify an Experienced and Reliable Scala Developer
-
Ask for references from ex-employers or team mates. Assess the Scala developer’s ability to work in a team. Also, find out about the leadership qualities of the developer.
-
Look for samples of past work to judge the problem-solving ability of the candidate.
-
Also, assess the candidate’s ability to meet deadlines, which is a sign of reliability.
-
Evaluate the ability of the Scala developer to think innovatively.
If you are convinced that the candidate is a good match for your business, you may begin the hiring process.
