Focus on Your Processes – Take Digitalization to the Next Level

Your customer service or sales department is undergoing digital transformation, yet instead of increasing efficiency, problems keep arising? Data gets lost, interfaces fail, and your IT team is stuck with endless workarounds?

Without professional backend development, serious issues can arise:

System crashes and performance issues because the backend is not designed for scalability
Data inconsistencies and security vulnerabilities due to faulty or insufficiently tested APIs
Growing technical debt, making every expansion extremely expensive and time-consuming
Missed deadlines because bugs and rework slow down the development process

Poorly designed backends don’t just cost money – they lead to system failures, frustrated customers, and inefficient workflows that hold your company back.

I develop high-performance, secure, and scalable backend systems that integrate seamlessly into your infrastructure and optimize your business processes.

Integrating Third-Party Services: Seamless Connectivity for Your Software

In today’s interconnected world, applications must communicate effortlessly with other systems. Whether billing systems, customer databases, or energy trading platforms, I integrate APIs and interfaces to enhance your software’s capabilities.

For instance, with NServiceBus, I ensure your applications remain stable even if third-party systems fail. Asynchronous communication and error recovery mechanisms prevent data loss and ensure reliable operations.

Additionally, I have extensive experience integrating SAP interfaces and harmonizing data using Azure Data Factory. These tools ensure your systems are always reliable and efficient.
