Enterprise APIs & backends
built with .NET.

.NET is our first choice for enterprise-grade backends. High-performance APIs, complex business logic, and long-lived enterprise applications — C# and .NET's type system, performance, and tooling make it the right call when correctness and scale both matter.

What We Build

.NET for enterprise-grade backends that have to be right

.NET's combination of static typing, high performance, and mature enterprise tooling makes it the right choice when the business logic is complex and correctness is non-negotiable.

REST & GraphQL APIs

High-throughput APIs serving web and mobile frontends. ASP.NET Core's performance benchmarks are consistently among the fastest web frameworks — not a marketing claim.

Enterprise System Backends

Complex business logic for operations-heavy businesses. Financial calculations, multi-step workflows, compliance requirements — .NET's type system catches errors that scripting languages miss.

Microservices Architecture

.NET microservices with gRPC communication, message queues (RabbitMQ, Azure Service Bus), and Docker-based deployment. We've migrated monolithic .NET apps to microservices without downtime.

Legacy .NET Migration

Migrating from .NET Framework to .NET 8/9 — unlocking cross-platform deployment, better performance, and modern C# features while keeping existing business logic intact.

Why .NET

When the backend has to handle complexity at scale

.NET isn't the flashiest choice — but for enterprise applications where correctness, performance, and long-term maintainability matter, it's hard to beat the combination of C#, Entity Framework, and ASP.NET Core.

1

Performance that scales

ASP.NET Core is one of the fastest web frameworks available. TechEmpower benchmarks consistently put it at the top. For high-traffic APIs, this isn't theoretical — it reduces infrastructure cost at scale.

2

C# catches bugs before production

C#'s strong static typing, nullable reference types, and pattern matching catch an entire category of bugs at compile time. For complex business logic with many edge cases, this matters more than developer velocity.

3

Entity Framework Core is mature

EF Core handles complex queries, migrations, and relationships cleanly. For enterprise data models with dozens of tables and complex relationships, it's the most productive ORM available.

4

Cross-platform now

Modern .NET runs on Linux, macOS, and Windows. Docker containers, AWS, Azure, GCP — it deploys anywhere. The days of .NET being a Windows-only choice are long over.

FAQ

Common questions about .NET development

.NET vs Node.js — which should I choose for my backend?

.NET for complex business logic, high-traffic enterprise APIs, and teams that value static typing and compile-time safety. Node.js for I/O-heavy APIs, real-time applications, and JavaScript teams that want a unified stack. We use both — we'll recommend based on your specific requirements.

Do you migrate from .NET Framework to modern .NET?

Yes — this is a common engagement. We assess the existing codebase, identify breaking changes, and execute the migration in a way that keeps the application running throughout. We've migrated .NET Framework 4.x applications to .NET 8 without service interruptions.

Can you integrate with an existing .NET codebase?

Yes. We start with an architecture review before making any changes — understanding the patterns, dependencies, and technical debt. Then we agree on an approach before extending or refactoring.

How long does a .NET enterprise project take?

A focused .NET API for a specific product: 12–20 weeks. A complex enterprise backend with multiple service boundaries, integrations, and data migrations: 24–40 weeks. Scope varies significantly by domain complexity.
