There are many reasons to hire a Haskell developer. Here are just a few: - Haskell is a very concise language, which can lead to more efficient code. - Haskell developers are often very experienced in functional programming, which can be beneficial for code that needs to be highly parallelizable or have other strict performance requirements. - The type system in Haskell is extremely powerful, which can help catch bugs early on and prevent errors in production code.
