Python with Big Data for Fintech Projects: Pros & Cons

Not so long ago there was a time when many financial institutions were exploding because of the volume, variety, and velocity of data coming from different sources. The Great Recession of 2008 greatly affected world banks and other financial systems. Thus, these organizations are highly dependent on modern technologies used in data science. While some financial institutions strive for fast processing, leading fintech companies tend to use advanced digital solutions to fully manage big data. 

Big data solutions enable business owners to streamline decision-making processes and offer customers superior services. They help to store, track and evaluate huge amounts of data, including customer information and security. Due to the great trust in technologies that can cope with growing volumes of customers and a large number of transactions, the overall level of services offered by financial institutions has also increased significantly. They cover such aspects of financial services like payments, investments, personal finance, lending, insurance, etc.

Big data using Python offers a promising way to develop efficient software products. They follow the needs of the fintech market – to collect, analyze, manage, visualize, and store huge volumes of data. They are analytics tools, robo-advisors, fraud detection systems, personalized recommendation engines, etc.

Java & Python in Big Data for Fintech Products

  • Very responsive and quick Java Virtual Machine (JVM)
  • Better сompliance сapabilities
  • Java-based ecosystem used in most Big Data tools (Hadoop, Spark, Storm, etc.)
  • Large tool pool for Big Data projects
  • Without the support of a read–eval–print loop (REPL)
  • Versatile language
  • Great libraries for Big Data (Numpy, SciPy, scikit-learn, etc.)
  • Readable & maintainable code
  • Rapid development
  • Slower than Java but supports a REPL environment & ETL (extract transform load) pipeline

Not surprisingly, other programming languages, like Python, tend to solve modern big data challenges. This seems obvious, but you should keep in mind an overview of the various technologies to make the right choice for your own fintech project. So, if you are going to analyze huge amounts of data, and then model and visualize them, you will need to carefully study Python and Java – what exactly each of these languages ​​will ultimately bring to you.

Today Java is widely used mainly because of the fast JVM – Java Virtual Machine, which makes Java also fast as compared to other languages. Many fintech companies prefer this technology. They develop big data solutions in a single code database and launch them on any platform. So, you can benefit from the ‘write once, run anywhere’ principle used by Java. If you change the hardware or software platform, you remain calm with Java. Besides, it provides the type safety necessary for data processing software. However, Java doesn’t have a great number of libraries for data science methods, compared to some other object-oriented languages, such as, for example, Python.

Python is a powerful library package to meet a wide range of big data requirements – gathering, modeling, visualization, audio/image recognition, etc. As a result, Python can do a lot for you if you’re planning a fintech project with big data – it’s relatively fast and scalable. Outside of many scripting functions, this language uses many advanced libraries such as Scrapy, Pandas, NumPy, Matplotlib, scikit-learn, and others. All Python libraries allow Data Scientists and Data Analytics to successfully handle scientific computing. They can be classified into several categories based on their functions, that are:

Python with over 200,000 libraries helps in this data-oriented world in various ways. Support for large libraries is commonly referred to as one of Python’s strengths. As a result, this language provides tools suitable for many data operations. First of all, it turns raw data into valuable ideas thanks to a powerful combination of Python with Big Data software. Secondly, thanks to the broad support of libraries, this object-oriented language helps implement machine learning algorithms. It should be noted that Python began to have many libraries for data analysis and machine learning not so long ago. This means that Python is considered by most experts to be the most effective programming language for big data, especially where it is extremely important to have well-analyzed data.

Python and Big Data: Real Use Case in FinTech

Python for Big Data: The Perfect Combination for FinTech - 3

Big data in the fintech industry helps manage risk, detect fraud, and meet customer needs. Given the high degree of risk associated with banking firms, ensuring customer satisfaction is one of the most difficult tasks for them. Customer retention – from ensuring the security of their transactions to providing them with the most relevant and advantageous offers – is a lifelong path for banking firms. Let’s see the real case of using technology in a large Investment banking company – Bank of America.

Bank of America – Long-Term Focus on Big Data

This is an international leader in providing services for consumer and corporate banking, insurance, investment banking, mortgage loans, wealth management, credit cards. Today this large banking company serves 70 million customers around the globe. In 2008, they realized that their customer base was declining. Special software analytics allowed them to figure out the reasons for this behavior. Through various sources where the data come from (sites, call centers, transcripts of interviews) they were able to establish the cause of the loss of customers. A group of analysts found that the comprehensive cash management system was too complex for the average customer. In addition, small banks began to satisfy consumer demand for this product, offering access to a simple and flexible cash management system. 

Eventually, this finding allowed Bank of America to quickly respond to changes in user behavior and make the right decision – to improve services with their banking system. As a result, the company declined the all-in-one offer. And in 2009, they launched a more flexible online product: CashPro Online, a working capital management platform and a separate mobile version of this product in 2010.

They don’t stop at these results and go on using technology. For example, in 2020, Bank of America uses a new data model to predict where the labor market is heading. Check out the video below to keep up with the latest news.
