CUSTOM .NET SERVICES
Advanced Microsoft Ecosystem Engineering
We architect highly scalable, strictly typed systems utilizing the modern .NET ecosystem. From modernizing legacy .NET Framework monoliths to building ultra-low-latency gRPC microservices, our engineers unlock the full power of C# and .NET 8+.
We build incredibly fast, modular backends. Utilizing ASP.NET Core Minimal APIs and Docker, we architect containerized microservices capable of handling millions of concurrent requests with an extremely low memory footprint.
We safely untangle aging enterprise monoliths. We utilize advanced refactoring patterns to incrementally migrate legacy .NET Framework 4.x applications to modern, cross-platform .NET 8, drastically reducing technical debt.
We build rich, interactive web applications without writing JavaScript. By leveraging Blazor WebAssembly and Blazor Server, we unify your frontend and backend architecture under a single, strongly-typed C# codebase.
We optimize internal system communication. We implement gRPC and Protocol Buffers (Protobuf) for inter-service communication, achieving serialization speeds up to 10x faster than traditional REST JSON APIs.
We build native desktop and mobile apps from a single codebase. Utilizing .NET MAUI (Multi-platform App UI), we deploy highly performant applications to iOS, Android, Windows, and macOS simultaneously.
We resolve severe database bottlenecks. Our engineers deeply optimize Entity Framework Core, eliminating N+1 query issues, implementing compiled queries, and dropping to Dapper (micro-ORM) for ultra-high-performance read operations.
We fully leverage the Microsoft Cloud. We design scalable architectures utilizing Azure App Services, Azure Functions (Serverless), and Azure Kubernetes Service (AKS), fully automated via robust CI/CD pipelines.
We lock down enterprise applications. We implement strictly enforced authentication and authorization utilizing Microsoft Entra ID (formerly Azure AD), OAuth 2.0, OpenID Connect, and strict Role-Based Access Control (RBAC).

.NET FAQ
What tech leaders ask about .NET before pulling us in:
The legacy .NET Framework (up to version 4.8) was tied strictly to Windows and is now in maintenance mode. Modern .NET (formerly .NET Core, now simply .NET 8+) is completely cross-platform, running incredibly fast on Linux, macOS, and Windows. It is modular, cloud-native, and significantly out-performs the legacy framework.
We avoid risky 'big bang' rewrites. Instead, we use the Strangler Fig pattern. We put a reverse proxy in front of the legacy app and slowly carve out specific features (like billing or user management), rewriting them as modern ASP.NET Core microservices. This allows us to modernize the architecture incrementally without stopping your business operations.
Blazor allows our developers to build rich, interactive Single Page Applications (SPAs) using purely C# and HTML, entirely skipping JavaScript. Blazor WebAssembly runs C# directly in the user's browser, while Blazor Server executes logic on the server via SignalR. For .NET teams, it drastically reduces development time by allowing code sharing between the frontend and backend.
.NET MAUI (Multi-platform App UI) is the evolution of Xamarin. It allows our engineers to write a single C# codebase and deploy it as a fully native application to iOS, Android, Windows, and macOS. It is highly performant and gives you access to native device APIs (like Bluetooth or cameras) without writing Swift or Kotlin.
EF is a powerful ORM, but it can easily generate bloated SQL queries (the 'N+1' problem). Our developers strictly profile database calls. We implement explicit Eager Loading, utilize compiled queries for high-traffic endpoints, and for complex reporting queries, we bypass EF entirely and use Dapper (a micro-ORM) to execute raw, ultra-fast SQL.
gRPC is a modern, high-performance Remote Procedure Call (RPC) framework. Instead of sending bulky JSON over REST, gRPC sends highly compressed binary data (Protobuf) over HTTP/2. We use gRPC exclusively for internal communication between microservices, resulting in significantly lower latency and CPU usage compared to traditional REST APIs.
.NET is inherently memory-safe, eliminating entire classes of vulnerabilities (like buffer overflows) common in C/C++. Furthermore, it integrates flawlessly with enterprise identity solutions like Microsoft Entra ID (Azure AD), providing battle-tested implementations for OAuth 2.0, OpenID Connect, and strict Role-Based Access Control out-of-the-box.
ASP.NET Core consistently ranks as one of the fastest web frameworks in the world on the independent TechEmpower benchmarks, heavily outperforming Node.js and matching or beating Java. Features like Minimal APIs and massive improvements to the Garbage Collector in .NET 8 make it incredibly efficient for high-throughput microservices.
