Hire Remote C# Developers

Hire Senior C# Developers Who Build Enterprise-Grade .NET Systems

C# is the backbone of enterprise Microsoft-stack applications. When your Azure-hosted platform needs to scale, your ASP.NET Core API needs a performance overhaul, or your legacy desktop software needs modernization, you need C# engineers who’ve solved these problems before — not developers learning on your dime.

Our C# developers have built enterprise platforms for Fortune 500 companies, financial institutions, and unicorn startups across healthcare, finance, and enterprise SaaS. They’ve delivered .NET solutions that manage billions in transactions, support thousands of enterprise users, and run on Azure with 99.99% uptime — in your time zone, in English, at 50% of US market rates.

What Our C# Developers Build

ASP.NET Core Web APIs & Microservices

Clean Architecture, CQRS, Domain-Driven Design — our C# engineers design and build the RESTful and gRPC APIs that enterprise systems run on. Properly layered, fully tested, and built to be maintained by teams who didn’t write them.

Enterprise Desktop Applications

WPF, WinForms, and MAUI — our C# developers have built and maintained enterprise desktop software used by thousands of users in regulated industries. They understand the unique performance, compatibility, and upgrade challenges of desktop development.

Azure Cloud-Native Applications

Azure Functions, Azure Service Bus, Azure DevOps, Azure SQL, Cosmos DB — our C# engineers are fluent in the Azure ecosystem and build cloud-native applications that leverage the full Microsoft stack.

Legacy .NET Framework Modernization

.NET Framework 4.x → .NET 6/8 migration. WCF → gRPC or REST. Monolith decomposition. Our C# engineers have navigated every dimension of .NET modernization at enterprise scale — without breaking production.

Blazor & Full-Stack .NET

Blazor WebAssembly and Blazor Server for interactive web UIs built entirely in C# — eliminating the JavaScript layer for teams that want to stay in a single language across front-end and back-end.

Client Success Story: Enterprise Desktop Software Modernization for a Multibillion-Dollar Conglomerate

A multibillion-dollar industrial conglomerate had a mission-critical WinForms desktop application used daily by thousands of internal staff across global operations — built on .NET Framework 3.5 and approaching end-of-life on the hardware it ran on. The business needed it kept operational and maintained cost-effectively while a longer-term modernization roadmap was developed. Our C# engineers embedded into the internal team, stabilized the build process, resolved an outstanding defect backlog, and introduced automated testing for the highest-risk modules. The engagement preserved a mission-critical workflow for thousands of employees at a fraction of onshore maintenance cost, and provided the tested foundation for a subsequent migration to WPF and .NET 6.

Client Success Story: ASP.NET WebForms Modernization for a Multibillion-Dollar Enterprise Services Group

A multibillion-dollar enterprise services company was running a customer-facing web application on ASP.NET WebForms — a stack that could no longer attract developers and was accumulating security vulnerabilities with each passing year. Our C# engineers designed a phased migration to ASP.NET Core with a React front-end, introducing Clean Architecture patterns, xUnit test coverage from zero to 68%, and Azure-hosted deployments with CI/CD through Azure DevOps. The modernized platform deployed to production with zero downtime, enabled the company to hire front-end engineers without requiring .NET expertise, and cut page load times by 70%. The technical modernization was cited internally as a prerequisite for the division’s growth strategy.

Why Companies Choose Our C# Developers

• Architecture-first: They design before they code — Clean Architecture, CQRS, and DDD aren’t buzzwords to our engineers, they’re daily practice
• Full .NET ecosystem fluency: From legacy WinForms to modern .NET 8 MAUI and Blazor, our engineers cover the complete Microsoft development stack
• Azure certified: Many of our C# engineers hold Azure certifications and have deployed and operated production Azure workloads
• English-fluent and time-zone aligned: Your C# developers work your hours and communicate clearly with your team
• 50% cost savings: Fully-burdened rates including salary, benefits, taxes, and HR

Engagement Models

• Individual C# Engineer — A senior C# developer embedded in your existing team. Ideal for adding an ASP.NET Core specialist, a Clean Architecture mentor, or an Azure cloud-native engineer to a team that already has .NET depth.
• C# Backend Pods (2–4 engineers) — C# developers paired with DevOps and QA in a coordinated squad. Common for teams migrating legacy .NET Framework applications, building distributed microservices, or launching new Azure-hosted services.
• Full .NET Teams (5–20+ engineers) — Complete engineering organizations for large-scale enterprise platforms, financial systems, or distributed applications where Microsoft stack dominance is a constraint.
• Contract-to-Hire C# Engineers — Trial a C# engineer on your codebase before making a permanent commitment. Senior .NET engineers make architectural contributions visible quickly — you’ll know within weeks.

How To Vet C# Developers

Our C# vetting screens for engineers who think in systems — not just in classes. The four-stage process:

1. Technical screening — .NET internals (value types vs. reference types, async/await semantics, ConfigureAwait(false), ValueTask vs. Task), dependency injection as an architectural pattern, CQRS and Clean Architecture principles, and Entity Framework Core query behavior. Over 90% of applicants do not pass this stage.
2. Architecture challenge — Design a multi-tenant ASP.NET Core platform with Clean Architecture layers, CQRS for command/query separation, and Azure Service Bus for domain event publishing. Evaluated on trade-off reasoning and failure mode awareness.
3. Live coding interview — Build an ASP.NET Core API endpoint with DI, middleware, validation (FluentValidation), EF Core queries, and an xUnit test suite. Code review on a C# codebase with real design violations embedded.
4. Communication screening — C# engineers in enterprise environments explain complex distributed systems to architects, product managers, and compliance teams. We assess communication clarity and technical authority explicitly.

What to Look for When Hiring C# Developers

Strong C# candidates think about dependency injection as an architectural pattern — not a configuration detail — and have nuanced views on when CQRS adds real value vs. when it’s overengineering for a CRUD application.

What strong candidates demonstrate:

• They understand the practical difference between IEnumerable<T> and IQueryable<T> at the Entity Framework level — and how this affects database query generation and performance
• They have a clear mental model for async/await in .NET: what ConfigureAwait(false) does, when ValueTask is appropriate, and how to avoid async deadlocks in ASP.NET Core
• They’ve profiled real .NET applications with tools like dotMemory, PerfView, or Application Insights — they’ve found real memory leaks, not just reviewed documentation
• They write behavior-focused tests using FluentAssertions and Moq — tests that verify domain logic rather than implementation details

Red flags to watch for:

• Using async void without understanding the unhandled exception implications — a common source of silent production failures
• No profiling experience — they’ve never diagnosed a memory leak or long GC pause in a .NET application
• Struggling to explain why IQueryable<T> matters for EF Core — or building LINQ queries that materialize entire tables before filtering
• Implementing CQRS or Event Sourcing by default for simple applications — a sign they’re applying patterns without evaluating the trade-offs

Interview questions that reveal real depth:

• “Explain what ConfigureAwait(false) does and describe a real scenario where omitting it would cause a deadlock in an ASP.NET Core application.”
• “You’re migrating WCF services to gRPC. Walk me through how you’d handle backwards compatibility for existing consumers during a phased migration.”
• “When would you implement Event Sourcing in a .NET system, and what are the operational costs you’re accepting when you do?”
