AyrinSoft C# and .NET software development

Custom .NET Software and GDS Booking Integrations

AyrinSoft builds enterprise .NET products and travel booking integrations you own.

Developer enablement

Focused training and debugging for programming and web teams.

Organizational solutions

Secure access layers and performance work on systems you already run.

Product engineering

Web and mobile applications on current Microsoft stacks.

Custom software you own
not throwaway prototypes

AyrinSoft designs, builds and supports custom software for companies that need reliable web platforms—not throwaway prototypes. Our core work is C# and ASP.NET Core: business applications, content platforms, and flight/hotel booking systems connected to Amadeus, Sabre, SITA and Accelaero.

Service-based since 2012

We have shipped service-based software since our first form-builder in 2012, so new products can talk to existing tools.

Startup ideas to working services

Startup ideas can move from concept to a working service; when it makes sense, early hosting can run on our infrastructure to cut setup cost.

Windows or Linux hosting

Web apps run on Windows or Linux. The database — MSSQL, MySQL, PostgreSQL, or MongoDB when document storage fits — follows the project.
