Insurance Innovators USA 2021, organized by Market Force Live, provided us with engaging sessions and insights into trends shaping the industry. We sum up key points and share our thoughts regarding commonly discussed predictions.

External sources of innovation

In a traditional approach, innovation was supposed to be driven by the internal capacity of an organization. So, achieved goals in innovation and R&D used to be an internal cost/benefit relation. That paradigm has started to shift in recent years and was clearly accelerated by the unexpected pressure from COVID pandemic.

Insurance companies understand the importance of collaborating with external experts to drive…

Are you looking for a programming language that is fast, easy to start with, and trending? The Julia language meets the requirements. In this article, we show you how to take your first steps.

What is the Julia language?

Julia is an open-source programming language for general purposes. However, it is mainly used for data science, machine learning, or numerical and statistical computing. It is gaining more and more popularity. According to the TIOBE index, the Julia language jumped from position 47 to position 23 in 2020 and is highly expected to head towards the top 20 next year.

Despite the fact…

Artificial Intelligence seems to be a quite overused term in recent years, yet it is hard to argue that it is definitely the greatest technological promise of current times. Every industry strongly believes that AI will empower them to introduce innovations and improvements to drive their businesses, increase sales, and reduce costs.

But even though AI is no longer a new thing, companies struggle with adopting and implementing AI-driven applications and systems. That applies not only to large scale implementations (which are still very rare) but often to the very first projects and initiatives within an organization…

The article covers setting up and using Kafka transactions, specifically in the context of legacy systems that run on JPA/JMS frameworks. We look at various issues that may occur from using different TransactionManagers and how to properly use these different transactions to achieve desired results. Finally, we analyze how Kafka transactions can be integrated with JTA.

Many legacy applications were built on JMS consumers with the JPA database, relying on transactions to ensure exactly-once delivery. These systems rely on the stability and surety of transactional protocols so that errors are avoided. …

In this article, we share our experience with building CI/CD for a multicomponent multi-language project. The article describes the structure of the pipeline set up and focuses on two important features needed in our project’s automation workflow: pipeline chaining and build variants.

The CI/CD usage is a standard in any application development process. Mobile apps are no exception here.

In our project, we have several iOS applications and libraries. Each application uses several components (frameworks) written in different languages. The components structure is as in the picture below:

The internal component contains all the core (domain) logic…

Kubernetes is currently the most popular container orchestration platform used by enterprises, organizations and individuals to run their workloads. Kubernetes provides software developers with great flexibility in how they can design and architect systems and applications.

Unfortunately, its powerful capabilities come at a price of the platform’s complexity, especially from the developer’s perspective. Kubernetes forces developers to learn and understand its internals fluently in order to deploy workloads, secure them and integrate with other systems.

Why is it so complex?

Kubernetes uses the concept of Objects, which are abstractions representing the state of the cluster. When one wants to perform some operation…

If we look at the claims adjustment domain from a high-level perspective, we will surely notice it is a very complex set of elements: processes, data, activities, documents, systems, and many others, depending on each other. There are many people who are involved in the process and in many cases, they struggle with a lot of inefficiency in their daily work. This is exactly where AI comes to help. AI-based solutions and mechanisms can automate, simplify, and speed up many parts of the claims adjustment process, and eventually reduce overall adjustment costs.

The claims adjustment process

Let’s look at the claims…
