.NET Development Services We Offer

End-to-end .NET services, from greenfield builds to legacy modernization.

Custom .NET Application Development

Enterprise-grade web applications, APIs, and backend systems using ASP.NET Core, C#, and Entity Framework. Architected for security and long-term maintainability.

.NET Modernization & Migration

Migrate from .NET Framework 4.x to .NET 8 without production downtime. Incremental strategies, including strangler fig and containerization, to reduce risk while unlocking modern performance.

.NET Microservices Architecture

Distributed .NET systems with clear service boundaries, independent deployments, and built-in resilience. Monolith decomposition done right.

Cloud-Native .NET Development

Cloud-native .NET applications for Azure, AWS, or GCP. Infrastructure-as-code, CI/CD pipelines, and observability baked in from day one.

.NET Performance Optimization

Diagnose and fix performance bottlenecks in existing .NET applications. Memory profiling, query optimization, caching strategies, async tuning.

.NET Consulting & Advisory

Architectural reviews, codebase assessments, and technical direction from engineers with production experience. Validate decisions before major investments.

When to Choose .NET Development Services

Consider .NET when:

  • Enterprise customers will scrutinize your product for security and compliance
  • You need predictable scaling without re-architecting every 18 months
  • You want a stack with 20+ years of Microsoft backing and a large talent pool
  • Your target customers already run on Microsoft ecosystems

No sales pitch. Just an honest conversation.

How We Architect .NET Applications

Clean Architecture principles: business logic independent of frameworks, databases, and delivery mechanisms. When .NET 10 arrives or you swap databases, your core code doesn't change.

API
Infrastructure
Application
Domain

Dependencies point inward to protect core business logic.

1

Domain Layer

Encapsulates core business rules and domain models in stable logic, isolated from frameworks and infrastructure.

2

Application Layer

Coordinates use cases and workflows through clear boundaries without embedding technical concerns.

3

Infrastructure Layer

Contains external dependencies such as databases, messaging, and integrations behind abstractions.

4

API Layer

Acts as a thin interface for external communication, keeping business logic independent of delivery mechanisms.

Why Teams Choose Us for .NET Projects

We're not the cheapest option. We're the option when the system matters too much to get wrong.

When teams reach out

Legacy .NET Framework system blocking cloud migration

Previous vendor left code but no documentation

Internal team stretched, need senior .NET expertise fast

Architecture needs validation before major investment

Need a partner who owns outcomes, not just tasks

How we reduce risk

Discovery first - Honest assessment before you commit
Pilot before expansion - Start contained, prove fit on real code
No vendor lock-in - You own 100% of code, docs, and infra
Transparent communication - Weekly syncs, full visibility
Exit-ready always - Every milestone leaves working software

No long-term contract required to begin. Discovery and pilot engagements available as starting points.
