About Interapp Development.
Nearly two decades of web application craft, one client at a time.
Company Overview.
Established in 2005, Interapp Development has been building web applications for nearly 20 years. We've evolved alongside the stack — from Visual InterDev to .NET 9 — while holding the line on the qualities that age well: clarity, stability, and direct accountability to the people we work with.
Our Foundation
We started in the ASP Classic and Visual InterDev era and have worked through every iteration since. That long view shapes how we build — we know which patterns last and which are just trending.
.NET Expertise
Core expertise in the .NET ecosystem since its inception. From .NET Framework 1.0 through modern .NET 9, we've continuously adapted and mastered each iteration.
Independent & Personal
As an independent consultancy, clients work directly with experienced developers who understand both the technical and business sides of the problem — no hand-offs, no agency layers.
