Using scripting languages like JavaScript or TypeScript, websites and web applications can be created fully dynamically. That means the HTML of the site is not only modified but largely generated initially through scripts. The data to be displayed (e.g. lists of texts) is retrieved from a server and the actual page is built in the browser. Since no full page reloads or URL changes are required, such applications are called Single-Page Applications (SPA) – complex, dynamic web applications available under a single URL. These can also be delivered as independent cross-platform apps.

There are several libraries (frameworks) that help developers create SPAs and offer standardization. The basic approach is similar: for different program states, specific views are defined and composed of reusable components like menus, forms, or text blocks to build the user interface.

Web servers form the basis for many applications. Helm & Walter IT-Solutions specializes in implementing distributed systems, cloud services, and web applications (web apps). We primarily rely on a Linux-based cloud server infrastructure that offers maximum flexibility and reliability for us and our customers.

For the management, setup, and customization of these servers, we use a variety of state-of-the-art technologies. This allows us not only to secure the operation of your (web) server-based application but also to create flexible and realistic development and test environments. This, in turn, minimizes risks during later deployment.

In most use cases we handle at Helm and Walter, the collection, management, analysis, and presentation of data are at the forefront. It doesn't matter how extensive these data volumes are – we find powerful solutions even for large amounts of data.

Databases are typically used for storing and processing data. These store entries in tables that are sometimes strongly interconnected. Searches or analyses can then be performed on this data. A good and professionally designed structuring of your data forms the basis for a high-performance IT solution. We support you in finding, developing, and implementing such a solid data model.

We can also help you with NoSQL (Not only SQL) systems for extremely large database systems.

Of course, we also assist you in migrating your existing data to a new system.

Software must run on a web server to receive, process, and respond to requests from clients (end devices such as PCs, mobile devices, or other servers). These programs can be created with different programming languages and technologies. At Helm and Walter, we primarily use Java, PHP, or Python for backend programming. PHP in particular has become the standard for such tasks. However, various base frameworks can be used.

An application isn't finished when it goes live – that's when the real test begins. Our DevOps expertise ensures that software runs reliably even under real-world conditions. We rely on active monitoring, automated deployments, proven tools, and experienced professionals to detect issues early and respond quickly. This guarantees smooth operations, continuous optimization, and high availability.
