Practical .NET software support and maintenance for organisations that rely on existing C#, .NET Framework, SQL Server and Azure applications and need experienced help keeping them dependable, maintainable and useful.
Maintain what works. Fix what hurts. Improve what matters.
Not every valuable application needs a rewrite. Sometimes the priority is simply to make an existing system easier to support, safer to change and more reliable for the people who depend on it.
When this service is a good fit
- Your original developer, supplier or internal expert has moved on.
- The application is business-critical but awkward to change or poorly documented.
- You need bug fixes, small enhancements or integration changes without starting a replacement programme.
- You have a .NET Framework or older C# application that still delivers value but needs dependable ownership.
- Your team needs extra capacity for a backlog of maintenance, reliability or upgrade work.
- You want an experienced technical view on whether to maintain, upgrade, wrap, extract or modernise parts of the system.
What I can help with
Application maintenance
Investigate and fix defects, reduce recurring operational problems and improve maintainability in existing .NET applications.
Enhancements and change
Deliver focused features and business changes without destabilising the parts of the application that already work.
Integrations and APIs
Repair or extend integrations, APIs, webhooks, scheduled processes and third-party connections.
Performance and reliability
Investigate slow or fragile areas across application code, SQL Server, services, deployments and Azure workloads.
Framework and dependency upgrades
Plan and deliver proportionate upgrades across .NET, libraries, hosting and supporting infrastructure where they reduce risk or unlock useful change.
Inherited system takeover
Establish how the software builds, deploys and behaves, identify technical and operational risks, and create a workable support plan.
Technology I am strongest in
C#, .NET and .NET Framework, ASP.NET, Windows applications, SQL Server, REST and SOAP APIs, Azure App Service, Functions, Service Bus, storage and related cloud services. I can also work across React and TypeScript where they form part of the wider application.
How an engagement can start
- Takeover and assessment: understand the application, source control, environments, dependencies, deployment process and immediate risks.
- Stabilise and prioritise: deal with urgent defects or reliability problems and agree a realistic maintenance backlog.
- Maintain and improve: work through agreed fixes, upgrades and enhancements in focused pieces of work or an ongoing arrangement.
- Modernise where worthwhile: use incremental modernisation when the evidence supports it rather than treating replacement as the default.
Need help with an existing .NET application?
Tell me what the software does, what technology it uses and what is making it difficult to support or change. A short outline is enough to start.
