The company runs on Microsoft
The business already uses Azure, Microsoft 365 or SQL Server, and the new system must integrate with them.
.NET
Microsoft's open, cross-platform framework for C# server apps. We choose it when a system is business-critical and must grow for years without a rewrite.
WHY WE CHOOSE THIS
A company's internal systems outlive any marketing website. .NET combines strict typing, performance and predictable support from Microsoft, so the system does not age in a year.
Complex business logic
The system calculates money, stock or rates, and a calculation error costs more than development.
Growing an existing .NET system
The company already has a .NET product, and it needs to be developed further, not rewritten from scratch.
Enterprise systems and ERP modules
ASP.NET Core and Entity Framework for accounting, request and document workflow systems.
APIs for web and mobile apps
ASP.NET Core Web API as the backend for websites, client areas and mobile apps.
System integrations
Data exchange services between the CRM, accounting, warehouse and external partners.
Legacy system modernization
Migrating applications from the old .NET Framework to modern .NET.

Other technologies in our stack
Why .NET and not Node.js?+
It depends on the task. Node.js is handy for fast web services and teams that write the frontend in JavaScript. We choose .NET for systems with complex business logic and Microsoft integrations, where strict typing reduces the risk of errors.
Does .NET lock us into Windows and Microsoft?+
No. Modern .NET is open source and cross-platform: applications run on Linux, in Docker and in any cloud, not only Azure.
Will it be easy to find developers for support?+
Yes. .NET and C# are among the most widespread enterprise platforms, so your own team or another contractor can maintain the system. We hand over the code together with documentation.
How long does development take?+
It depends on the amount of business logic and the number of integrations. We give exact timelines after describing the processes and architecture, and launch the system in parts so the business benefits sooner.
For critical systems, stability matters more than technology trends.
.NET development at GVSPACE means a backend for systems that a company's money and processes depend on: accounting, requests, billing, partner integrations. We use ASP.NET Core, Entity Framework and C#, and deploy applications to Azure, AWS or the client's own servers. We design the system so it can be developed for years, with tests, documentation and an architecture any .NET team can understand.
