Expert .NET Consulting Services
Build Modern, High-Performance Backends with .NET
.NET is Microsoft's cross-platform, high-performance runtime for building APIs, services, and cloud-native apps. Our .NET consulting helps teams modernize legacy systems and deliver world-class backends.
What Is .NET and Why Do You Need a Consultant?

Total Shift Left helps teams modernize from .NET Framework to the latest .NET, design clean architectures, build minimal APIs and microservices, integrate Entity Framework and Dapper, and deploy to Kubernetes, Azure App Service, or AWS.
At Total Shift Left, our .NET consultants bring deep, hands-on experience from dozens of enterprise implementations. Whether you are evaluating .NET for the first time, migrating from another platform, or looking to optimize your existing .NET setup, our team provides the expertise you need to succeed. We serve as your trusted .NET consulting partner — from initial assessment through implementation, training, and ongoing support.
