Sandpiper Software

Legacy .NET systems, modernized.

35+ years keeping business-critical software running — and bringing it forward. Custom development, integration, and long-term support from a single senior engineer.

What We Build

🔄

Legacy System Modernization

The .NET Framework app that runs your business but nobody wants to touch. Incremental migration to modern .NET, WebForms and WCF exits, and re-platforming without a risky big-bang rewrite.

🌐

Custom Web Applications

Tailored solutions built for your specific business needs and workflows

🔗

Integration & Automation

Connect your tools and automate repetitive tasks to boost efficiency

🛠️

Ongoing Support & Maintenance

Long-term partnerships to keep your software running smoothly

Sound Familiar?

Most of our work starts with one of these.

A .NET Framework application that can't move to modern .NET
WebForms or WCF with no clear upgrade path
The developer who built it retired, and the knowledge went with them
It runs the business, and everyone is afraid to change it
Security scans keep flagging it, and vendor support has ended
It works, but it's slow, brittle, and expensive to maintain

None of these get better on their own. They get more expensive.
