As the necessity for FinTech services grows, businesses in the sector must respond to the demand and grow with it. That’s why they’re turning to Python, C++, Kotlin, Ruby, Go, Swift, and Java development services. Why are these languages ideal for FinTech?

Java

Java has been the go-to programming language for FinTech for much of the sector’s existence. That’s largely because it’s extremely secure, thanks to features like the Java virtual machine (JVM), which prevents the program from performing insecure or malicious functions. Security is, of course, a fundamental concern for banking operations.

Java runs in a virtual environment, making it highly accessible and compatible with multiple platforms and devices. It’s high-performing, an essential feature where money is concerned. Java also has longevity on its side and is perfect for large, long-term projects, making it ideal for well-established banking institutions and newer, popular apps and tools.

Python

This efficient, high-performance language is steadily increasing in usage across FinTech. With readable, concise code and scalability, it’s easy to turn around projects quickly and keep up with customer demands and the competition.

Developers use the language for many different applications, such as web-based services, cryptocurrency, and data science and analysis. With a vast library full of resources and frameworks, it’s also a good choice for open-source projects.

C++

This general-purpose language has been around for three and a half decades, meaning it’s stood the test of time. Its super-fast speed makes it suitable for FinTech applications — after all, people need to access and use banking services quickly. C++ comes with a vast library and reusable code to facilitate easier programming.

While it’s not as widely used as it once was in the sector, it’s still the language of choice for areas like quantitative and qualitative finance and analytics, as well as other complex, advanced projects.

Go

Go, short for Golang, is one of the newer FinTech languages, released by Google in 2009. The language shares a lot of similarities with Java, such as its high performance and speed. It is also lightweight and simple.

Go can handle multiple tasks simultaneously, making it the perfect language for apps and programs that need to handle many different requests at once without risking performance issues or, worse, crashing.

Kotlin

A solid, newer alternative to Java, Kotlin is used to create Android applications. Because it is interoperable with Java, many developers choose it for standard FinTech tools and programs. While Java is the better choice for backend development, Kotlin is excellent for frontend development.

One way it beats Java is that generally speaking, it makes fewer errors — an essential facet of a FinTech language. It can also compile to the JVM, so you can easily swap out Java for Kotlin and take advantage of the security it offers. You’ll find plenty of tools and support for the language, too.

Ruby

Ruby is most well known for its widely-used framework, Ruby on Rails, which facilitates easier writing of code and expedites the development process. Many FinTech businesses, including the popular Square, use Rails, which makes it possible to build secure and reliable products.

Both the language and framework are highly stable — a must for banking and any financial process — and come with plenty of support, both in terms of tools and a large community that’s eager to provide additional resources and help with troubleshooting. Ruby is flexible and allows for easy, fast development.

Swift

Reliable and comprehensible, Swift was developed by Apple, but it is used by iOS and non-iOS developers alike. In terms of FinTech, it’s a great choice for large projects that need to be completed quickly. With its readable, easy-to-understand syntax, developers can build products in a short timespan.

Often considered an alternative to Objective C — this is, in fact, why it was initially created — it is both significantly faster and less prone to errors than its older counterpart. These qualities are necessary for building quality FinTech products.

FinTech has become such a pivotal feature of the modern world that it’s a wonder how we ever got by without it. Now, in the midst of an unprecedented global pandemic, we need efficient, accessible banking services more than ever before, especially with so many people stuck at home but still in need of support in the financial sector.

It’s essential, then, that software developers work hard to create FinTech products that people want and need. This requires leveraging the best tools to build these platforms — including the right languages. When choosing a language and development service for your project, consider the requirements and the features that best support them. You have a wide array of possibilities — these are only some of the many choices out there.
