Services
Freelance services for companies that run business-critical platforms on the Microsoft stack, especially energy utilities, grid operators and other regulated industries. The first three come from years of client work in production; Azure AI is shown through personal reference projects.
.NET Development & Modernization
Backends and REST APIs with .NET / ASP.NET Core and SQL Server: new features for existing platforms, or modernizing them. That means .NET version upgrades (for example .NET 5 to .NET 8), replacing deprecated dependencies, resolving breaking changes and tuning performance. At a DAX-listed utility this cut page response times and CRM data retrieval by up to 75%.

Azure Migration, DevOps & Terraform
Move applications from on-premises Windows Server / IIS to Azure App Service with Private Endpoints, Key Vault and Application Insights, and put delivery on rails. For a DAX-listed utility I wrote the complete Terraform infrastructure for the portal across multiple environments and all Azure DevOps YAML pipelines, which replaced manual deployments, and set up monitoring and alerting for production.

Dynamics 365 Integration
Connect Dynamics 365 CE with portals and backend services for business-critical processes such as customer onboarding, PV system registration and grid connection requests. Integration layers in .NET via the XRM SDK with early-bound entity models, C# plugins, JavaScript form scripts, customizing and solution deployment, in both energy-sector engagements since 2019.
