.NET development that scales with you

Senior C# engineers building ASP.NET Core APIs, microservices and mission-critical business logic — and rescuing the legacy .NET systems nobody wants to touch.

What we deliver

ASP.NET Core Web APIs

REST and gRPC services with clean layering, versioning, OpenAPI docs and authentication that holds up under audit.

Microservices

Service decomposition done carefully — message-driven with Service Bus or RabbitMQ, and only where it actually earns its complexity.

Entity Framework & Dapper

Data layers tuned for real query patterns, with the N+1 problems and missing indexes found before they reach production.

Legacy Migration

.NET Framework 4.x to .NET 8, WebForms to modern stacks, and monoliths untangled incrementally without a risky big-bang rewrite.

Real-time with SignalR

Live dashboards, notifications and collaborative features that stay stable across reconnects and scale-out.

Performance Tuning

Profiling, caching strategy, async correctness and allocation reduction — measured against real production traffic, not synthetic benchmarks.

Why teams choose Cogicode for .NET

The .NET ecosystem rewards depth. Getting async right, choosing between EF Core and Dapper for a given query path, knowing when a microservice is genuinely warranted and when it just adds latency — these decisions compound over the life of a product.

Cogicode engineers average more than ten years in the Microsoft stack. Every engineer is personally vetted by our founder, Sandeep Kumar, before joining a client team, and each one works inside your repository and your review process.

That means you can read every commit, question every design decision and change direction whenever you need to — the same visibility you would have with an in-house hire, at a fraction of the total cost.

Frequently asked questions

How much does .NET development cost at Cogicode Technologies?

Senior .NET engineers at Cogicode Technologies start at $15 per hour and go up to $20 per hour depending on seniority and specialisation. There are no recruitment fees, and you can scale the engagement up or down monthly.

Can you migrate our old .NET Framework application to .NET 8?

Yes. We audit the existing solution, identify incompatible dependencies, and migrate incrementally so the application stays shippable throughout. Most migrations run alongside normal feature work rather than freezing the roadmap.

Do you write tests?

Yes. Unit and integration tests are part of the delivery, not an optional extra. We wire them into your CI pipeline so failures block merges rather than being discovered in production.

Which .NET versions do you support?

We work across .NET 6, 7, 8 and 9, plus legacy .NET Framework 4.x when a migration is involved. New services are built on the current long-term-support release unless your environment requires otherwise.
