FinTech is the widely used term denoting all the technologies, tools and software apps facilitating financial transactions and management. From simple mobile banking apps to investment and stock apps to insurance apps to payment gateways and mobile wallets to cryptocurrencies, all come under the broad umbrella term of fintech.

The global FinTech market is continuously growing and expanding bringing more and more conventional transactions within fintech solutions. According to a Statista forecast, the fintech sector is likely to experience a yearly 12% growth in the coming years creating a market valuation of 188 billion euros by the end of 2024.

Do you want to develop a unique fintech app? Supposedly, you have already validated the app idea and decided on your target platform. You need to take a call on the most relevant technology stacks that fit your fintech app project. Let us guide you here regarding this.

Frontend Stack for Fintech Apps

The frontend or the client-side refers to the representation layer that the app users mainly interact with. Since the frontend deals with the elements for the look, feel user experience and user interactions, choosing the right frontend tech stack to engage users.

The key frontend technologies used in fintech app projects includes the following.

• Hypertext Markup Language (HTML): HTML is mainly used to show content in an accessible and interactive manner on web pages. HTML for years happens to be the most reliable language for showcasing text content on web pages. Now the latest version of HTML5 further extends the original capabilities through a set of dynamic features.
• Cascading Style Sheets (CSS): The CSS is used by web projects to incorporate various elements corresponding to the look and feel such as font sizes, font styles, color, layout, and several other visual elements.
• JavaScript: JavaScript is the dynamic programming language that allows web developers to incorporate interactive elements. JavaScript is used in web projects through several leading frontend frameworks such as jQuery, AngularJS, ReactJS, VueJS and a few others. JavaScript frameworks by using JSON format further make things easier for the developers to understand and use the code.
• TypeScript: TypeScript is many webs developer's new trending programming languages. The language is as dynamic as JavaScript with a few pros and cons in comparison

Backend Stack for Fintech Projects

Backend or the server-side of a web project refers to the configuration and tools used to facilitate faster and desired server response against the user queries from the frontend of the app. Choosing the backend stack for fintech web projects is essential to ensure faster loading time, robust security and ease of transactions and interactions.

Some of the leading backend programming languages include the following.

• Python: For most FinTech apps, Python is regarded to be the most popular programming language because of its easy coding approach, a wide range of open-source libraries full of reusable fintech components, and transparent and straightforward syntax leading to fewer errors and bugs and robust community support. No wonder Python is now used by most of the leading fintech apps, including Zappa, Robinhood, Figo, and many mobile banking and e-wallet apps.
• C++: C++ is another leading programming language used widely for fintech app development. C++ is particularly preferred because of its core capabilities in handling quantitative finance and analytics. It is also regarded as one of the most efficient languages to ensure high-speed execution and quicker time to market.
• C#: C# can be regarded as the advanced version of C++ offering a more equipped object-oriented programming language for developing highly dynamic fintech apps using the Microsoft ecosystem of technologies. The language created mainly for the .NET framework of Microsoft ensures optimum security and ease of development powered by a large developer community and a robust repository of tools.
• Ruby: Ruby has been famous as a programming language across many banking software app projects. The popularity of Ruby for fintech projects lies in the ease of asset management, dashboard development, e-wallet and mobile wallet development and several other fintech solutions. Ruby also offers some inbuilt security features popularly sought after by fintech projects.

Database Solutions for Fintech Projects

Apart from the frontend and backend development, the database is another key area of the technology stack for any web app project. Now, when it comes to fintech apps, the choice of database technology is not just crucial for smooth app performance but also for robust and uncompromising app security.

The leading database technologies used across fintech app projects includes the following.

• SQL Database: SQL comes as a relational database and it uses its SQL language for making data queries. For fintech app projects, SQL is considered a better option as it uses a highly structured format ensuring easier access and categorization. The stringent data structure of the SQL database is also helpful in improving app security.
• NoSQL Database: NoSQL comes as a non-relational database and in contrast to the SQL database, it doesn't store data in a structured or predetermined format. Though this database technology ensures more storing capacity because of doing away with structure, it doesn't fit well into fintech app projects. This means that NoSQL databases easily store unstructured data and don't have some predefined schemas.
• PostgreSQL: It is the most widely used database technology for most fintech apps. It is popular because of its lightning-fast response time to queries. On top of that, this database technology provides an array of additional features and capabilities for improved security such as transparent data encryption, data masking and several others.

Several full-stack development options for Fintech apps such as MEAN, MERN and MEVN. Allowing two-way data binding MEAN stack is particularly helpful for fintech app projects. Look at this comprehensive guide on MEAN stack developers for a better idea about the pros and cons.

Summing It Up

Fintech apps, after bringing a revolution to the way we make transactions and make financial planning have become staple components of personal and business finance. While the growth opportunities with the fintech apps are relentless, your scope to take on this opportunity largely depends upon the execution and choice of technology stacks.
