Freelance .NET & Azure Engineer for Complex Software Challenges

Experienced specialist in software development, cloud, integration, and technical architecture.

Heroz Software gives organizations direct access to more than 22 years of software development experience. As a freelance software engineer and Azure architect, I work directly with development and architecture teams on complex technical challenges and business-critical software.

Experienced Freelance Specialist, Ready to Contribute

Do you need additional expertise temporarily, lack specific knowledge within your team, or have a complex software challenge that needs to be solved? As a freelancer, I work directly with your organization and team.

I combine deep technical expertise with a pragmatic approach. I can independently take ownership of complex challenges while working just as effectively with existing development, DevOps, and architecture teams.

How I Can Help

Development of robust and maintainable applications using Microsoft .NET and C#, from new features and complex business logic to complete backend solutions.

Design, development, and modernization of cloud solutions on Microsoft Azure, with a focus on reliability, security, scalability, and manageability.

Reliably connecting applications, systems, and external services through APIs, messaging, and integration patterns.

Technical architecture, modernization of existing applications, and step-by-step migration to modern .NET and cloud architectures.

More Than 24 Years of Software Development

My name is Dennis Heldens. I am a freelance software engineer and Azure architect with more than 24 years of experience in software development.

Throughout my career, I have worked on a wide range of software, integration, and cloud challenges. My expertise lies primarily in backend development, complex business logic, data processing, system integration, and Microsoft Azure.

I am used to quickly understanding complex technical environments and taking responsibility for technical solutions. I focus on solutions that are not only technically sound, but also practical to implement and maintainable over the long term.

• Microsoft .NET & C#
• Microsoft Azure
• Azure Functions & App Services
• Azure Service Bus & Messaging
• APIs & System Integration
• Cloud Architecture
• CI/CD & DevOps
• Infrastructure as Code
• Modernization of Existing Applications

Flexible Team Augmentation

As a freelancer, I can be engaged for a specific assignment, to temporarily strengthen an existing team, or to address a technical challenge for which specific expertise is not available within the organization.

I work as part of the existing team, adapting to the client's way of working, development processes, and technical environment.

Additional seniority and technical capacity when your team needs it temporarily.

Direct support with complex .NET, Azure, integration, and architecture challenges.

From analysis and technical design through development, implementation, and handover.

From Technical Challenge to Working Solution

A complex technical challenge does not always start with a clear answer. Sometimes, the first step is understanding the existing situation. In other cases, the challenge lies in architecture, integration, or making the right technical choices.

I can contribute at different stages of a project:

Assessing the technical challenge and mapping the existing environment.

Defining a suitable architecture and technical solution.

Building the solution using modern and proven technologies.

Connecting systems, automating processes, and deploying solutions to production.

Continuously improving, modernizing, and maintaining existing solutions.

Pragmatic. Technically strong. Personally involved.

Good software is not about using as much technology as possible. It is about finding the right solution to the problem that needs to be solved.

I therefore take a pragmatic approach and make deliberate technical choices. When existing technology and infrastructure work well, there is no need to replace them unnecessarily. New technology is introduced when it genuinely adds value.

As a freelancer, I work directly with the client and the team. This keeps communication lines short, enables quick decision-making, and ensures clear ownership.
