What Hauptwerk-Consult does

Hauptwerk-Consult is a one-person independent IT consultancy operated by Gert Jan Schipper from Veenendaal, Netherlands, trading under the DBA name GJS - IT Solutions & DevOps. The practice delivers Azure cloud architecture, DevOps implementation, CI/CD pipelines, Terraform-based Infrastructure as Code, C#/.NET custom software development, and SQL Server performance tuning for enterprise and mid-market clients, while also serving a secondary niche of Hauptwerk and Sweelinq organ system owners requiring specialized IT tooling.

The technical portfolio combines traditional freelance consulting with a set of purpose-built tools targeted at the organ-systems vertical: the Organ Configurator (WPF/C# application for hardware detection and configuration), System Reporter (Azure Functions + Cosmos DB telemetry with a React dashboard), Startup Launcher (C# automation with encrypted scripts), Remote Imaging & Restore Platform (Hyper-V, Clonezilla, Azure Storage), and an automated Installer Pipeline (Azure DevOps + GitHub Actions). The broader services span .NET Windows Services, REST API integrations, Hugo-based web infrastructure, and PowerShell/Bash scripting.

The business operates as a sole-proprietor freelance model with no external funding, no disclosed revenue, no employees beyond the principal, and no patents, awards, or formal partnerships. Pricing is engagement-based and not publicly disclosed, with the platform noting multi-year contracts. Customer acquisition is driven primarily by direct referrals and the gjschipper.nl website, with geographic scope centered on Europe.

Broad incumbents

• Slalom: Management and technology consulting firm with strong Azure cloud and DevOps practices serving enterprise and mid-market clients. Comparable in targeting enterprise cloud transformation mandates, but offers a much broader portfolio of strategy, data, and engineering services.
• Insight Enterprises: Global IT solutions and services provider with significant cloud, DevOps, and managed services capabilities. Overlaps on Azure infrastructure and DevOps consulting offerings though delivered as part of a much broader hardware, software, and services portfolio.
• Capgemini: Global IT services and consulting giant with dedicated cloud and DevOps transformation practices. Competes for the same enterprise Azure/DevOps engagements but as part of a full-spectrum strategy-to-operations portfolio.
• Cognizant: Global IT services provider with cloud and DevOps consulting practices serving enterprise clients. Comparable on Azure engineering delivery but as one capability among a much wider digital, IT, and business process portfolio.
• Deloitte Consulting: Big Four consulting practice with extensive cloud engineering and DevOps transformation offerings. Competes for large enterprise Azure mandates though typically as part of strategy-led engagements rather than pure technical delivery.

Direct peers

• Rackspace Technology: Multi-cloud managed services and cloud-native consulting firm with strong Azure capabilities including DevOps, Kubernetes, and infrastructure automation. Comparable in core Azure/DevOps delivery competency though operating at hyperscale rather than freelance boutique.
• Avanade: Joint Accenture-Microsoft venture focused exclusively on Microsoft enterprise services including Azure cloud, DevOps, and application development. Directly comparable as a deep Azure specialist serving enterprise clients, though at vastly larger scale than this one-person practice.
• Xebia: Dutch-origin boutique IT consultancy specializing in cloud, DevOps, Agile, and software craftsmanship. Highly comparable on Azure/DevOps delivery model and European mid-market/enterprise focus, though operates with multiple consultants rather than solo.
• Netlight: Boutique Nordic-origin IT consulting firm known for senior-consultant-led delivery in cloud, DevOps, and digital engineering. Closely comparable in freelance/senior-consultant DNA, though operating with a larger network of independent consultants rather than a single operator.

Regional players

• Info Support: Netherlands-based IT services and consulting firm with .NET, Azure, and DevOps practices. Comparable on .NET/C# development and Azure consulting competency within the Dutch market, though at materially larger scale.
