Senior C# engineers building ASP.NET Core APIs, microservices and mission-critical business logic — and rescuing the legacy .NET systems nobody wants to touch.
REST and gRPC services with clean layering, versioning, OpenAPI docs and authentication that holds up under audit.
Service decomposition done carefully — message-driven with Service Bus or RabbitMQ, and only where it actually earns its complexity.
Data layers tuned for real query patterns, with the N+1 problems and missing indexes found before they reach production.
.NET Framework 4.x to .NET 8, WebForms to modern stacks, and monoliths untangled incrementally without a risky big-bang rewrite.
Live dashboards, notifications and collaborative features that stay stable across reconnects and scale-out.
Profiling, caching strategy, async correctness and allocation reduction — measured against real production traffic, not synthetic benchmarks.
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.
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.
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.
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.
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.
