Kotlin is an open-source programming language that is used not only for Android app development but also for web and server-side development and more. Kotlin in fintech gained popularity because of the multiple benefits it has to offer the financial services industry:

  • Safety. Kotlin’s strong type system and null safety feature reduce the risk of programming errors that could cause financial losses. The type system also provides more robust type inference, which helps the compiler catch errors earlier. Together with its clean syntax, Kotlin is a great choice for developers who prioritize safety and reliability.
  • Expressiveness. Kotlin’s type inference and higher-order functions allow developers to express complex financial algorithms and business logic that are easy to read and maintain. This is especially helpful for complex financial systems.
  • Conciseness and reduced code. Kotlin’s concise syntax, extension functions, and lambdas reduce the code needed to perform complex operations, making it easier to maintain and debug.
  • Interoperability. Financial legacy systems built using Java are challenging and expensive to replace them. As an alternative, organizations choose to update and modernize these systems to integrate with new ones. Kotlin allows for modernizing legacy systems without starting over because it can easily integrate with existing Java codebases.

Considering all of the above, Kotlin is an excellent choice for building fintech applications, particularly when in the hands of experienced specialists. Hence, it’s no wonder that when it comes to fintech development Kotlin is one of the most sought-after programming languages. This can make it difficult to find suitable engineers. To help you find the perfect tech partner for your project, we have compiled a list of the top 10 fintech development companies offering developers on various terms – go check them out.
