FinTech Industry: Challenges Developers Might Face

As a FinTech business holder, there are some issues that are quite crucial to FinTech app users and which you must consider very seriously. Let us discuss the primary concerns in detail.

  • Security

For FinTech startup enterprises, security is a major concern. Fintech apps have to deal with delicate financial data making them easy targets for cybercriminals. These companies must ensure that they build highly secure web applications and follow everything that enhances cybersecurity. This involves incorporating strong verification and encryption methods, keeping track of possible security threats, and preparing for any critical security issue that might occur unexpectedly. If an enterprise fails to secure its FinTech application aptly, this might affect its reputation and finances. So, to protect your integrity and reliability among clients and avoid huge losses, this has to be taken quite seriously.

  • High traffic

Many FinTech app companies face this issue very commonly. Business enterprises have to guarantee that the application they create can deal with huge traffic without crashing or slowing down. FinTech applications must have greater accessibility and efficiency because clients must be able to access their data and manage transactions in real-time.

  • Analytics

Since data is at the heart of the FinTech industry, startup enterprises must have strong analytical efficiency. When you analyze data, it provides you with important insights into customer preferences and habits, transaction models, and market trends that will help them improve their business strategy and enhance overall growth.

Analytics becomes an important factor for Fintech startups when it comes to risk control. While working with sensitive data, these applications must be able to locate and intercept defrauding transactions. With strong analytical efficiency, FinTech startup enterprises can easily evaluate credit risk and make crucial data-oriented decisions about lending.

How does Ruby on Rails help FinTech deal with these challenges?

Ruby on Rails has everything one needs to create a trustworthy, robust, and productive Finance application. It deals with all primary issues faced by FinTech startups. Here are a few reasons why Ruby on Rails is the perfect match for FinTech.

  • Ruby on Rails for FinTech deals with security concerns.

Ruby on Rails is specially customized to handle security concerns and is equipped with many inbuilt features that make the process of creating safe web applications easier for developers. Features like cross-site scripting(XSS) security, SQL injection security, and security against CSRF concerns. RoR protects your application from cyber attackers trying to exploit general weaknesses.

  • Ruby on Rails for FinTech tames traffic upsurge issues with its scalability.

The RoR framework helps FinTech startups deal with traffic upsurge concerns by providing scalability in the following ways:

  • FinTech startups can use RoR for horizontal scaling by adding more servers to handle the rising traffic. It is designed to function with cloud-based infrastructure that helps these startups add further instances speedily and efficiently if handling traffic demands so.

  • RoR has inbuilt caching systems that help FinTech startups work on the improvement of their application’s efficiency by minimizing the request that must be made to the database. Frequent caching of accessed data by RoR lightens the database load and boots the app’s performance during heavy traffic upsurge.

  • RoR supports nonsynchronous processing, which boosts application efficiency and deals with high traffic by allowing the processing of requests in the background. This frees up resources and minimizes the load on the server during heavy traffic upsurges.

  • RoR also functions efficiently with load-balancing solutions that allow Fintech startups to disperse traffic across many servers/instances. This load balancing improves application efficiency and ensures that even during heavy traffic upsurges, the application is effectively accessible.

Therefore, the scalability features of RoR, as discussed above, are extremely useful to FinTech startups, especially when they are dealing with traffic upsurge concerns. By capitalizing on these attributes, FinTech startups can guarantee the accessibility and peak performance of their application, even during heavy traffic.

RoR assists FinTech startup companies deal with analytics-oriented challenges by integrating with its data analysis equipment, in the following ways:

  • RoR integrates with data visualization tools like D3, Chart, and Highcharts to create reciprocal and interactive data visualization. FinTech startups will thus have a better understanding of the data and decide on trends and data that might not be variable in the raw form.
  • RoR integrates with data warehousing solutions like Redshift and Amazon to store and control massive data. This helps FinTech startups amalgamate data from different sources and do complicated queries and analyses.
  • RoR integrates with machine learning tools like TensorFlow and Scikit-learn to create forecast models and make data-oriented decisions. This helps FinTech startups point out specific motifs in data and forecast future practices like recognizing high-risk clients or anticipating market trends.

Which front ends work well with the RoR backend for FinTech Apps?

If you are considering front-end frameworks while creating FinTech applications, there are plenty of choices that are compatible with Ruby on Rails:

  • ReactJS: It is a very popular framework, compatible with RoR. Gaining popularity for its modular design, speedy rendering, and recyclable components, developers can easily integrate ReactJS with RoR using the React-Rails gem. Thus, they have a set of generators and associates that make the development process easier.
  • AngularJS: It is another renowned front-end framework compatible with RoR. It provides developers with a complete set of tools to create complicated web applications. Some of these tools are data binding, dependency injection, and routing. Developers can use the Angular-Ruby gem to integrate AngularJS with RoR. This gives them a set of commands and generators to simplify the development of AngularJS applications.

  • VueJS: A developing front-end framework, VueJS is also compatible with RoR. When it comes to simplicity, flexibility, and efficiency, VueJS is simply perfect. Developers can use the VueJS-Rails gem to integrate VueJS with RoR. This gives them a set of helpers and generators that simplify the development of VueJS applications.

  • EmberJS: This front-end framework, also compatible with RoR, provides a powerful set of tools that make the creation of complicated web applications smooth. Some of these tools are data binding, routing, and testing. Developers can use the Ember-Rails gem to integrate EmberJS with RoR. This gives them a set of helpers and generators that simplifies the development of EmberJS applications.

All of the front-end frameworks discussed above are remarkable in their own way. They can all be used with Ruby on Rails to develop FinTech web applications. Choosing the correct framework will mostly depend on the requirements of each project and how professional the development team is.
