ABOUT THE CUSTOMER
ConnectYourCare is one of the largest health savings providers in the US. The company offers comprehensive solutions supporting tax-advantaged accounts. It provides employers with convenient ways of administering consumer-directed health care (CDH) while offering benefit services to employees, revolutionizing the way they use CDH accounts. ConnectYourCare became part of Optum Financial in July of 2021.
ABOUT THE PROJECT
Due to a major acquisition, the client was conducting the large, ambitious task of updating and integrating their main platform written in Java. Multiple development teams had to cooperate on each part of the stack in order to upgrade and maintain the system. The Rumble Fish team, in collaboration with a US partner, Space Inch, was responsible for an entire reimagining and rebuilding of the platform.
CHALLENGE
Our client had multiple legacy apps that needed to be unified in their design and technology with that of the acquiring company, a Fortune 10 public health care company. In this case, we dealt with a portal more than 12 years old serving 2.5 million clients, an enormous amount of historical data and customer touchpoints. We had to make sure every single piece of information exchanged between the portal and its user was properly branded. In addition to updating front-end features, the client’s primary customer portal also uses e-mails and text notifications and is integrated with several vendors such as printed correspondence providers. Finding and updating every customer touchpoint with such an extensive codebase required deep expertise in Java, an eye for detail, and a disciplined, goal-oriented team.
Another challenge to overcome was the proper project management of such an elaborate and strenuous task. With many Java developers working simultaneously, we had to enable an efficient methodology and working process. Sounds like a lot? It’s only a fraction of the project! Keep on reading to learn the details.
SOLUTION
This was not a typical Java project. This unique challenge required our team to do some substantial investigative work as well. The first two steps on the roadmap were quite straightforward:
to upgrade the look and feel of the front-end,
to remove the hard coded branding references from the sources, which our experts executed by using their IDE's (Integrated Development Environment) support for regex-based and structural search and replace operations.
What came after that was when the real fun began. As mentioned earlier, the portal has a few more customer-facing elements and features than just the web front-end. Knowing these functionalities existed, we needed to track down all their entry points - schedulers, workflows, manual triggers - and move up the ladder to detect all sources of potentially branded information. One by one, we updated CMS entries, database dictionaries, and environment variables to make sure we no longer referred to the old branding anywhere. While the task we had to do was not programming per se, it had to be done by Java software developers, due to the necessity of understanding the code and using the right tooling to find all the touchpoints.
All of this had to be done thoroughly and methodically as it's easy to get lost in this amount of codebase. Besides rebranding the features, the Rumble Fish team was also responsible for smooth project management.
The Rumble Fish development team is outstanding, some of the best engineers we’ve worked with. Their level of engineering intelligence allowed us to achieve all our goals. As a full-stack development partner they have a high standard for code quality, UX, communication, and all-around efficiency. They are one of our go-to resources for all web and mobile development. Highly recommended.

COO of SpaceInchBattle of the Giants: Java vs TypeScript vs Solidity. Best Coding Languages for Fintech projects
In software development, fintech projects tend to be especially demanding and challenging: on one hand, users expect top-notch UX, on the other - there are certain standards you need to follow to enable the highest level of security and privacy. Combined with a huge amount of data to process, fintech software becomes the trickiest to develop. Which programming languages are suited to hit the spot when it comes to fintech projects? Let’s find out!
Fintech is all about replacing or augmenting traditional financial services with innovation and the latest technology, such as cloud, Internet of Things, Artificial Intelligence, big data, etc. Its main aim was initially to help financial institutions improve their back-end systems to enable smooth operation. However, there has been a significant shift in the way financial technology is utilized - nowadays, it’s less about the bank and more about the user and making their life simpler. Modern fintech products help people manage their investments and money from their smartphones and wearables while also solving the most aggravating problems of traditional banking. What does it mean from a technical perspective? There are several common challenges to overcome in almost every fintech project. Let’s see which programming technology is the best suited to deal with them.
The most common fintech software challenges from the developer’s perspective
Fintech apps are not just a piece of software - people trust them with their finances, investments, and savings. They use them for loans, money transfers, insurance, and any other type of financial transaction. That’s why the process of developing a fintech product is such an intricate one. To choose the right technology stack, we need to be aware of the most common challenges that await the developers.
Ensuring data security
According to the research conducted by the University of Maryland, a cybercrime attack happens every 39 seconds. Hackers are constantly trying out new tricks to get into our wallets or steal our data, and fintech companies are their newest prey. If you want your product to succeed in this high-risk market, ensuring the top level of security is an absolute must.
Enabling the smoothest user experience
Users nowadays are accustomed to fast, on-demand access to almost any service they require. Obviously, it’s even more expected when it comes to their financial assets. Taking care of your fintech product usability might be tricky - various legal requirements and security assurance might interfere with the overall user experience. As research shows, 79% of users point to app usability as the most important factor they consider when using an app. Load time is regarded as equally crucial.
Supporting multi-cloud platforms
Complex business and IT infrastructure might be a huge turnoff for any person willing to turn their fintech idea into a working piece of software. The perfect solution for this issue is cloud architecture. Cloud-ready applications not only enable proper scalability and agility but also minimize the infrastructure complexity. Fintech software developers need to be fluent in hybrid cloud architecture to create a truly multi-cloud platform. There is no turning back as 93% of companies use at least one cloud-based IT service.
Choosing the right technology stack to tackle all the requirements
Taking into account all of the issues above, choosing the right technology stack for your fintech project may seem like the biggest challenge of them all. Every programming language has its strengths and weaknesses which makes the decision quite difficult. It’s important for the stack to be future-proof and able to support emerging tech trends to fully leverage their potential. Technologies you opt for, let’s say, a healthcare app, will require a different set of assets than a fintech product. Considering all the intricacies of financial technology, we chose three languages that work the best in fintech projects.
3 best languages to use in a fintech project
Choosing the right technology stack to tackle all the requirements.
Java has been around for over 25 years now, and since then it has continuously proven to be the first choice for financial software developers. It holds third place in the TIOBE rating of the top preferred programming languages and, according to the Stack Overflow 2021 report, for almost 36% of developers, it’s their most commonly used language. There are several reasons why Java is just perfect for fintech software projects, let’s look into the most crucial ones.
A proven track record for major financial institutions
Java has been trusted by traditional banking & finance giants for decades now. Its object-oriented models along with fraud-proof security features have proven to be suitable for large projects with huge amounts of data processed every minute. Besides that, Java, being a veteran language, has been tested and evaluated in various banking software development projects. Due to its holistic backward compatibility, applications written 20 years ago, still run in the latest JDK.
A plethora of libraries and features
Java has one of the most impressive and extensive ecosystems, with many libraries and frameworks for all domains and businesses. Being the finance industry’s favorite, each new Java release is packed with features created with fintech projects in mind. This will make the whole development process faster and much more efficient.
The wide availability of open source tools
If a tight budget is one of your concerns, Java is here for you with a wide range of free and easily accessible big data tools. There are more advantages of using an open-sourced Java feature - it assures both flexibility and agility while saving your developers lots of time and hassle.
TypeScript - get things done faster (and bug-free).
Loved by 73% of developers, TypeScript is one of the most efficient technologies to use. The fintech market, being very competitive and time-sensitive, needs a tech stack that’s able to quickly build an MVP (minimum viable product) or to update and enhance what’s already been developed. TypeScript is just the tool for that.
Error-prone coding
TypeScript is a JavaScript superset that introduces optional static typing (in contrast to JS dynamic typing). It means that a once declared variable won’t change its type and is only able to take certain values. The developer is being alerted if there are any type-related errors before they hit the production phase. The possibility of catching bugs early in the process saves everyone lots of stress, time, and, last but not least, money.
Fast and agile refactoring
Fintech products must stay compliant with regulations and standards, which means there is a potential for frequent updates and changes in the software. TypeScript comes in especially handy when there’s a need to refactor the software without changing its behavior and keep the code robust. Its ability to spot mistakes makes refactoring easier and faster, even when dealing with large codebases.
Clean code that speaks for itself
TypeScript is very straightforward - one can clearly see the intent behind another developer’s code. Why is that important? When the work is distributed among various engineering teams, as it often happens in complex product development, one team can easily identify what the other had in mind while typing particular code lines.
Solidity - because Blockchain is here to stay.
Fintech is all about innovation and utilizing the latest technology to solve the problems of modern finance management. That’s why we simply cannot overlook Blockchain when it comes to present-day money dealing. Decentralizing finance (DeFi) is becoming much more than just another buzzword and Blockchain is the technology that makes it possible.

If you’re trying to build a fintech app capable of processing instant settlements and easily improving money flow by eliminating middle-men, Blockchain and smart contracts might be just the thing. That’s the reason why the financial sector is the primary investor in blockchain technology, with a market share of 46%. And if your product roadmap does include smart contracts development, Solidity is the perfect programming language.
What is the best programming language for fintech software development?
Although there is no one right answer when it comes to picking the best technology for fintech projects, the three mentioned above really stand out in the crowd. Which of them will suit your project best depends on your business requirements, roadmap, amount of data you’ll be processing, etc. Knowing the capabilities of different coding languages is the first step in choosing the right technology stack.
