Hire top talented Clojure developers with UltraGenius

Clojure is a robust and Lisp dialect functional programming language used for providing Big Data solutions and social networking security. Clojure has a functional programming way of writing code which provides several tools to avoid mutable state, implements functions as first-class objects and iterate loops in a recursive manner instead of side-based loops. It is best used for data mining and large scale predictions.

Want to hire Clojure developers on your own? Here are the skills you must look for while hiring a Clojure developer

Hiring Clojure developers might be an intricate task for you if you are a non-technical manager. Clojure is a robust, lisp-dialect, functional programming language designed for providing big data solutions and dealing with massive amounts of data. Clojure is a functional programming language and has the concept of immutable objects, embeds functions as first-class objects, and provides recursive iterative loops instead of side-based loops providing more security.  But, hiring the most skilled Clojure developers among thousands of developers is a challenging task for anyone. So, UltraGenius is here to assist you while recruiting the top talented Clojure developers on your own. UltraGenius understands your job requirements and gets you only the top developers who have in-depth knowledge of software development.

The following skills you must look for while hiring a Clojure developer – 

Knowledge of Java Virtual Machine (JVM)

Clojure programming language provides the Java Virtual Machine (JVM) type system for hosting programs, threads, Garbage Collection, etc. The functions are compiled to JVM bytecode. Java Virtual Machine is a run-time platform that provides the Clojure developers achieve platform-independent code by compiling code first to Java bytecode which can be run on any platform.

Understanding of LISP

LISP stands for list processing and is a set of programming languages designed for data manipulation of strings. LISP supports the software implementation computing symbolic expressions. Clojure belongs to lisp-dialect. As lists are present in LISP, the maps, sets, and vectors are present as first-class data structures in Clojure programming language.

Knowledge of Concurrent programming

One of the greatest advantages of Clojure is its multi-threading way of programming and execute programs in parallel with reducers with clojure.core.reducers/fold. As the core data structures such as map, vectors, and sets are immutable, they are easily shared between multiple threads avoiding race condition. On the other side, Clojure allows Clojure developers to change the state but maintains the consistency when it does so.

Knowledge of Clojure libraries

Clojure provides a vast set of libraries which are very helpful to Clojure developers while Clojure programming. Clojure provides a continuous data inter-change in backend with ClojureScript in the frontend through a very popular library and format to set up data serialization. Clojure Spec library is used to generate comprehensive data for testing and define data specifications and functions to test data.

Experienced in working with Version Control System (VCS)

Clojure developers must know how to use Git, the most popular version control system. It is this system that helps teams in collaborating and organizing your code as well as maintaining frequent changes that occur in the code-git has helped with reviewing old codes and comparing them with new ones by pulling files from it’s repository or managing commit history. Alongside this should have knowledge of adding (with git add), pushing (add + push = upload), pulling (pull + delete=upload) & committing besides branching & merging which allow developers to work independently on a piece of code.

Understanding of Clojure testing frameworks and TDD style

Clojure provides a set of APIs called clojure.test testing namespace for using the Midje framework testing classes. Midje provides top down and bottom up test driven development (TDD) styles. Midje has powerful in-built features such as tabular facts, meta-constraints, checkers, etc. Apart from this, the Clojure developers must be aware of the popular Clojure libraries like Lacinia, HoneySQL and HugSQL, Ring, Compojure and Bidi, danielsz / system.

Good grasping on functional programming

Functional programming is a paradigm of building software by composing pure functions without mutating state and data. Functional Programming enhances the productivity of the program. It provides immutable data structures that are not faced with race conditions and thereby employs safe multi-threading. Functional programming comes under the “Declarative Paradigm” in which the program logic is written without explicitly describing the flow control.

Clojure's Runtime Polymorphism

The core data structures in the Clojure Runtime are defined by Java interfaces. Using proxy, Clojure provides support for implementing Java interfaces in Clojure. Moreover, Clojure supports polymorphism along both  custom hierarchies and class with multi-methods. Clojure provides a faster form of Polymorphism with protocols but also they are limited to class polymorphism only, taking the advantage of JVM’s existing potential for invocation.

Ability to cross browser compatible code

You must hire the Clojure developers based on their ability to write cross browser platform compatible code. With cross-browser compatibility, your website will have an increasing traffic and it will deliver the best user driven experience, independent of the browser on which it is running on.

Well versed using Lambda expressions

One of the core features of Clojure is functional programming and lambda expressions. Lambda expressions provide one line concise syntax for writing functions. These functions are not named and hence cannot be called but they can be passed as parameters to higher order functions such as map, reduce, sort, zip, and forEach are some examples of higher order functions.

Experience implementing higher order functions in code

Clojure uses higher order functions which makes your code more abstract without affecting the internal functionality. A higher order function takes another function as an argument and returns the output in the form of a function. Higher order functions make the code concise which improves its readability. Check if the Clojure developers have implemented  map, sort, reduce, filter, and forEach functions and know their utility in programming.

Familiarity with ClojureScript and ClojureCLR

ClojureScript is a powerful tool and target environment for Javascript. ClojureScript provides a compatible platform for with an advanced compilation mode. The code gets first compiled to Javascript and then runs in any web browser or Node.js runtime. Clojure also provide its own Common Language Runtime (CLR) which is written in C# and utilizes Microsoft’s Dynamic Language Runtime (DLR).

Familiarity with Clojure's dynamic compilation

Clojure exhibits dynamic code development that means you can grow your program with loading data, add features, correct and fix bugs, test the code without any interrupt. To enter and execute commands in an interface, Clojure provide REPL (Read-Eval-Print-Loop) interface, which is a simple programming interface that allows Clojure developers to enter commands, execute them, and examine their results. Anything you load using load-file or enter using REPL is compiled to JVM bytecode automatically and can be even compiled ahead of time if required.

Proficient in writing optimized and readable code

The Clojure developer must have a strong problem solving skill because it helps developers to utilize existing solutions for the projects more efficiently, thinking abstractly, and enables them to write pseudocode for their project. The developer must know how to debug the code as well. Also, check if the Clojure developer is able to write clean and concise code and can fluently communicate with other team members while explaining the code.

Connect with the top 1% Clojure developers of the world at the lowest prices

Clojure is a robust and general-purpose functional programming language featuring a vast set of immutable data structures. Clojure follows code-as-data strategy of LISP programming languages which is used in symbolic interpretation in AI and is helpful in data mining. But, recruiting the best Clojure developers is not an easy task when a large no. of Clojure developers are competing to grab the job opportunities.
