Services

I help organizations with advice, design, and implementation of custom software based on Microsoft .NET and Microsoft Azure. Below is an overview of frequently requested services and technologies.

Expertise and Services

Custom software development with C# and .NET (ASP.NET Core, minimal APIs, background services, worker services).
Web application development with Blazor (Server and WebAssembly) and Angular, including backend APIs, component-based UI, and responsive design.
Design and development of (RESTful) APIs (OpenAPI/Swagger, authentication/authorization with OAuth2/OIDC, Azure API Management).
Integrations between existing systems (ERP/CRM/finance) such as Exact, AFAS, PerfectView, etc. via services, API connections, webhooks, and message-based integrations.
Setting up Microsoft Azure landing zones (network, identity, governance, security, cost management).
Design and execution of cloud migrations from on-premise applications to Azure (App Service, Azure Functions, Azure SQL, Storage, Key Vault).
Serverless solution development with Azure Functions, Event Grid, Service Bus, and Storage Queues.
Setting up DevOps pipelines in Azure DevOps and GitHub Actions for CI/CD, automated builds, tests, and deployments.
Mobile app development with .NET MAUI for Android and iOS, including backend API integration and push notifications.
Windows desktop application development (WPF/WinUI), tools, and utilities to support internal processes.
Automating process steps with PowerShell scripts, scheduled tasks, and Azure Automation to minimize repetitive work.

Technology Stack

Microsoft Azure (App Service, Functions, Static Web Apps, Storage, Service Bus, Containers, App Environments, Azure SQL, Key Vault, API Management)
.NET, ASP.NET Core, Blazor Server, Blazor WebAssembly, .NET MAUI
C#, TypeScript, JavaScript, PowerShell, SCSS/CSS
Azure DevOps, GitHub, GitHub Actions, YAML pipelines, CI/CD, Infrastructure as Code (e.g., Bicep, Terraform, or ARM templates).
REST API, OpenAPI/Swagger, OAuth2, OpenID Connect, JWT, webhooks

Methodology

Intake: jointly clarifying the problem, scope, and success criteria.
Architecture & design: proposal for technical architecture, security, and hosting.
Proof-of-concept / MVP: quickly building a first working version to validate assumptions.
Implementation & testing: iterative development, automated testing, demos.
Delivery & support: deploy to production, monitoring, documentation, support.

Where possible, I work according to the Agile/Scrum methodology, so development proceeds in short, well-tuned steps and allows room for interim feedback and adjustments. Regarding cost agreements, working with a fixed total price or on an hourly basis is possible, with a preference for a fixed price. This provides clarity upfront about the investment and the result.
