The Ultimate Finance Tech Stack for 2024

The fintech world is growing fast, with innovative minds shaking up traditional banking and transforming the way we manage our money.

Choosing the right tech tools is key, as it influences the product's security, its ability to grow, and how well it performs. In this post, we'll dive into how to pick the right tools for success and explore the core components of a fintech tech stack. 

Welcome to your guide on fintech technology.

What's in a Fintech Tech Stack?

Think of a fintech tech stack as the combination of programming languages, tools, and technologies used to build financial apps. It's like a three-layer cake:

• The front end is the part that interacts with users.
• The back end is the engine that runs everything on the server.
• The data layer is where all the app's information lives. 

On top of these, there are APIs, cloud services, containerisation, DevOps tools, and security frameworks that make up the rest of the fintech stack. With our user-friendly approach, building your fintech solution is easier than ever. Dive into banking technology solutions that make for a smooth and efficient fintech tech stack.

Why is the Tech Stack so Critical for Fintech Innovation?

By 2026, the fintech market is expected to balloon to $324 billion, transforming how businesses operate and how customers access services. In this rapidly evolving landscape, staying ahead with the latest technologies/trends is vital for developing modern, secure, and robust financial tools and solutions. 

The fintech sector is always on the move, pushing the boundaries with technologies like blockchain, artificial intelligence, and the Internet of Things. As these technologies become more integrated into financial services, understanding and choosing the right tech stack in 2023 will be more important than ever for innovation and growth.

Choosing the Right Tech Stack for Your Financial Business

Picking the perfect tech stack for your financial venture is all about finding the right balance. It's a mix of being in tune with the latest trends and taking a good, hard look at what you really need.

Consider Your App's Features and Focus

Before jumping in, it's crucial to think about what your project aims to achieve. Look at the features you want to include, how complex the app will be, and who it's for.

The fintech world is vast, covering everything from managing personal finances and making payments to banking. Lately, there's also been a boom in insurance tech and regulatory technologies.

While there's no one-size-fits-all answer in software development, many fintech apps share common features like:

• User dashboards for financial insights and reporting.
• Some level of automation.
• Push notifications.
• Payment gateways or digital payment options.
• Robust security measures to safeguard sensitive information.

Ensure Regulatory Compliance

For fintech companies, staying on the right side of regulations is crucial for protecting both users and the business itself. With the industry being a prime target for cyber threats, including data breaches and fraud, it's vital to guard against these risks.

Developing your financial software means keeping various regulations in mind and making sure your tech stack aligns with these requirements.

Technologies in machine learning can be pivotal in spotting unusual behaviour patterns that might suggest fraud, such as money laundering.

Put Security and Scalability First

Your tech stack choice significantly influences your app's ability to scale and stay secure.

Given that fintech apps handle sensitive data, prioritising security is non-negotiable. The technologies you choose play a crucial role in how effectively the system can protect against cyber threats, such as SQL injections/cross-site scripting (XSS). Opting for security-enhanced libraries, focusing on data encryption, and picking frameworks known for their security features can mitigate these risks.

But scalability is about more than just handling big numbers. 

By establishing a solid infrastructure, fintech companies can focus on innovation without being bogged down by the need to keep the app running smoothly and efficiently.

The FinTech World's Top 7 Game-Changing Technologies

Intelligent Gadgets and Secure Payments:  The future is bright for IoT (Internet of Things) as more smart devices connect us in ways we've only imagined. The focus is on enhancing contactless payments; with smartphones leading the charge today, many more devices could soon join the fray.

Tailored Experiences: Personalization is shaping the financial industry, pushing FinTech companies to craft services and communications that resonate on a personal level. This means everything from customised websites and emails to apps, notifications, and even chatbots are being designed with the user in mind, especially in retail banking.

Digital-First Banking: The rise of challenger or non-traditional banks is changing the game. They're winning over customers with their tech-savvy, lower fees, and better interest rates, all without the hassle of traditional banking processes. 

Neo banks like Mercury and Brex are:

• Examples of this shift.
• Offering banking services that are just a click away.
• Making the idea of visiting a physical bank obsolete.

Challenger banks are growing, shaking up the financial landscape despite scepticism from traditional banking. With a significant portion of millennials distrustful of traditional banks and open to switching to FinTech solutions, the narrative that FinTech might replace banks is gaining ground. 

However, many startups are open to partnering with banks to access their customer base, offering innovative solutions in return.

AI and Automation Revolution: The adoption of FinTech globally is pushing banks to evolve. From chatbots taking over customer service roles to robots boosting efficiency, AI is making its mark. For instance, the Mizuho Financial Group in Japan is planning a significant shift towards digitalisation, replacing thousands of jobs with AI by 2026.

The Cloud Era: Cloud computing revolutionises managing and delivering financial services. FinTechs leveraging the cloud can scale quickly, process vast data, and access powerful computing without heavy physical infrastructure. This move enhances security and real-time data analysis and ensures seamless integration of services, offering scalability and flexibility.

Blockchain's Breakthrough: Blockchain is transforming financial transactions with transparency, efficiency, and security. This technology allows for decentralised transactions, cutting costs and removing intermediaries. It's being applied across various FinTech areas, from supply chain management to digital currencies, for secure and efficient operations.

RegTech's Rise: Regulatory technology, or RegTech, is becoming indispensable in navigating the complex banking and finance regulations world.

RegTech solutions streamline compliance, enhance risk management, and improve operational efficiency by utilising AI, machine learning, and big data. This helps financial institutions manage risks, comply with regulations, and navigate the regulatory landscape more effectively.

By embracing these technologies, the FinTech sector is innovating and creating a more transparent, cost-effective, and secure financial ecosystem.

Selecting the Right Tech Stack for Fintech Software Development

HackerRank, a tech job platform, lists the top six programming languages for financial firms as C++, C#, Ruby, Java, C, and Python. When deciding on the best technology stack for the backend of a fintech application, it's essential to weigh the pros/cons and consider how they fit with the app's requirements. 

The choice of programming language should be guided by both the technical demands and the business objectives of your project.

From what we've seen, pairing the Django framework with Python often hits the mark perfectly. Here's why:

Python is the go-to programming language in the fast-evolving fintech sector, setting it apart from the banking world, which traditionally leans towards Java and C++. Python stands out as one of the most adaptable and dynamic languages, rapidly becoming a favourite among fintech innovators compared to more conventional choices.

This shift towards Python and Django reflects a broader trend of digital transformation within the industry. For instance, Bank of America is a prime example of a traditional financial institution embracing fintech innovations, transitioning its old IT infrastructure to a more modern, fintech-focused tech stack.
