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

Hiring Haskell developers might be an intricate task for you if you are a non-technical manager. Haskell is one of the well known languages used for research purposes and implementing functional programming in applications, and hiring the most skilled Haskell developers among thousands of developers is a challenging task for anyone. So, UltraGenius is here to assist you while recruiting the top talented Haskell 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 Haskell developer – 

Steadfast knowledge of HTML and CSS

Knowledge of HTML (Hypertext Markup Language) and CSS (Cascading Style Sheets) is very important for a Haskell developer. You must hire such a Haskell developer who has practiced and worked deeply with these technologies. Knowledge of Flexbox and CSS Grid, in addition to Bootstrap, Semantic and Structural Styling, and Foundation is a must to a Haskell developer. Along with this, the Haskell developer should be well-versed in Javascript libraries especially jQuery and CSS grid systems.

Javascript fundamentals + ES6

Javascript is most widely used language in developing dynamic web applications and helps Haskell developers integrate back-end with the front-end easily. The Haskell developer must be clear with the fundamental concepts of Javascript language. ECMAScript 6 (or ES6) is the current version of ECMAScript and is widely used by developers up to a large extent. The Haskell developers must be familiar with these ES6 skills –  

  • Arrow functions
  • Blocked scope constructors let and const
  • Advanced object literals
  • Template literals
  • Multi-line strings
  • Modules
  • Module loaders
  • Binary and octal literals
  • Reflect API
  • Proxies
  • Classes
  • Destructuring assignment

CSS Pre-processors and Frameworks

A CSS pre-processor is a program that extends the functionality of CSS and compiles it into regular CSS. SASS, PostCSS, SCSS, and LESS are the extensions of regular CSS and developers use them for useful functions such as math functions, color manipulation, to write better inline documentation, to easily integrate CSS tools and CSS codebase, and much more. It makes developers write lines of code in very less time because of its in-built functionalities.

You must check the Haskell developer’s knowledge of Bootstrap and Material UI, as these components streamlines the development process and ensures that a web application looks best.

Knowledge of Haskell libraries

Haskell libraries helps a Haskell developer while Haskell development. Check if the Haskell developer knows about these popular libraries – vect, vector, binary, Hascore, attoparsec, aeson, stringsearch, moo, and text. Other most frequently used libraries include conduit, functional graph library, graph automorphism library, streams, arrays and references library, edison, Yesod, http-client, Pointless Haskell, GenUtil, hspec, and many more.

Experienced in working with Version Control System (VCS)

Haskell developers need to be very knowledgeable about version control systems, like Git. Developers mostly use Git for their work because it helps them collaborate and organize code by tracking frequent changes that occur in the code. In addition to this knowledge, Haskell developers also need to know how to execute commands such as add, push, pull and commit – these commands allow developers on a team project working independently from one another so they can all do their own thing with some guidance from others when needed. Alongside this knowledge of how git works comes branching techniques and merging which allows different versions of code created by a group of people or individuals- usually programmers-to be combined together without any hassle if something goes wrong at some point during the process.

Excellent understanding of testing frameworks and tools

For skilled Haskell developers, testing has become the most demanding skill. To be a successful Haskell developer you must know about Jest for unit testing, Enzyme for React and Mocha or Chai for other frameworks. For end-to-end testing, Selenium is necessary to master along with Cucumber and Cypress tools; Nightwatch will simplify browser automation in tests that need browsers; Karma is needed for integration tests.

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.

Knowledge of front end technologies like React or Angular

Haskell developers must know about front end technologies and frameworks particularly React.js or Angular.js. These front-end frameworks are greatly required in today’s market. React is popular for its faster development of Single Page Applications while Angular uses interpolation, dependency injection, and eliminates coding mistakes by using the strongly typed Typescript that resolves many challenges faced by the developers.

Ability to cross browser compatible code

You must hire the Haskell 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

Haskell’s core feature 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

Haskell 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 Haskell developers have implemented  map, sort, reduce, filter, and forEach functions and know their utility in programming.

Experience with web markup and UI, UX Concepts

The developer must have a firm understanding of element positioning, displaying the elements, and making components interactive, semantic markup, and other related UX Concepts so they can design the product with the best quality. The developer must be experienced in developing visual effects in presentational markup. For, example – How the heading appears, making text larger and putting weight to it, and giving which color to it, and which markup can include captions, bind columns, and row headings to table cells. 

Familiarity with Immutable objects

Haskell follows OO programming approach which makes every object in Haskell immutable. When you want to change the contents of any object, you have to make a replica (or copy) of that object and replace only the bits which needs to be changed.

Proficient in writing optimized and readable code

To streamline the development process,  the Haskell developers must be proficient writing clean and high-performance optimized code that is understandable by all the team members.
