.NET systems
we build and deliver

Six production system types each chosen where .NET's performance, type safety, and enterprise ecosystem add genuine value.
01

ASP.NET Core REST APIs

High-performance REST APIs for enterprise applications. Minimal API or controller-based, OpenAPI 3.1 documentation, JWT authentication. .NET 8 performance is competitive with Go and Node.js on benchmark throughput.

Minimal API · NestJS alternative · OpenAPI 3.1

02

Enterprise Web Applications

Complex data-driven web applications with intricate domain logic, multi-step workflows, complex permissions, reporting, and third-party integrations. C#'s type system handles domain complexity well.

DDD · CQRS · MediatR

03

Blazor Web Applications

C# web UIs with Blazor — server-side or WebAssembly. Right for teams that want to stay in C# for both backend and frontend. Particularly useful for enterprise internal tools.

Blazor Server · WASM · Data-driven UI

04

.NET Microservices

Independently deployable .NET services with Docker, Kubernetes (AKS or EKS), Dapr for service mesh, gRPC for service communication, MassTransit for message-based async patterns.

Docker · ECS / AKS · gRPC · MassTransit

05

Windows Service Migration

Migrating legacy Windows Services, WCF services, or WinForms/WPF applications to modern .NET — web APIs, microservices, or cross-platform console applications.

NET Framework 4.x · Migration · .NET 8

06

Azure-Native .NET Applications

Applications deeply integrated with Azure — Functions, Service Bus, Cosmos DB, Azure AD B2C, and DevOps pipelines. .NET's Azure SDK integration is the strongest of any language.

Azure Functions · Service Bus · Cosmos DB

Who hires us

seal-warning

CTOs replacing legacy .NET Framework systems

Your .NET Framework 4.x application is Windows-only, slow, and preventing cloud migration. We assess the migration path, identify the real risks, and deliver the .NET 8 upgrade with zero production incidents.
warning

Engineering leads building enterprise APIs

High-throughput REST APIs, complex domain logic, strict type safety requirements. .NET 8 Minimal API is genuinely one of the fastest web frameworks available — we'll show you the benchmarks.
chart-line-up-1

Microsoft/Azure-stack enterprises

Existing Azure investment, Azure AD, Azure DevOps, compliance posture tied to Microsoft tooling. .NET is the obvious choice — we build it properly with DDD, CQRS, and test coverage that holds up over time.

Teams inheriting a .NET codebase that needs improvement

Technical debt, poor test coverage, EF Core N+1 queries in production, ASP.NET MVC patterns that haven't moved with the language. We audit, prioritise, and improve systematically.

Inheriting a .NET codebase or planning a migration?

We'll assess your existing system, map the technical debt, and give you a prioritised improvement plan before any development begins. Free — no commitment.

Modern .NET.
Not 2012 patterns.

Four ways an EB Pearls .NET project differs from legacy MVC code ported to a new runtime.
chart-pie-slice

Modern .NET — not legacy patterns

Minimal APIs, record types, pattern matching, primary constructors, required members, .NET 8 performance improvements. We write modern C# — not ASP.NET MVC patterns from 2012 ported to a new runtime.

Domain-Driven Design where complexity demands it

Aggregates, value objects, domain events, repositories, and bounded contexts. DDD adds real value in systems with complex business rules. We apply it appropriately — not universally.
shield-check

EF Core and Dapper both in our toolkit

Entity Framework Core for standard data access. Dapper for performance-critical queries where raw SQL with type-safe mapping is more appropriate than LINQ translation. We choose based on the query — not the tool.

Azure and AWS — not just Azure

We deploy .NET to Azure for Microsoft-ecosystem clients and to AWS (ECS, Lambda, Elastic Beanstalk) for AWS-first clients. We do not force platform choice based on our preference.

How we compare

Dimension Node.js / Python EB Pearls .NET 8
Raw API throughput Very good
✓ .NET 8 Minimal API — among the fastest across all frameworks
Enterprise domain complexity Manageable
✓ C# type system + DDD handles complex domains exceptionally well
Azure ecosystem integration Good
✓ .NET Azure SDK is the strongest integration of any language
Type safety (end to end) TypeScript (Node) / type hints (Python)
✓ C# strict typing from DB schema to API response — no gaps
Windows legacy migration path ✗ Major rewrite required
✓ Incremental .NET Framework → .NET 8 upgrade path available
AI / ML workloads ✓ Python wins

Every question answered.

Can't find what you need?

Microsoft and Azure environments, complex enterprise domain logic, strong type safety requirements, compliance governance favouring Microsoft tooling, or high-performance API requirements. .NET 8 is one of the fastest web frameworks across any language.

ASP.NET Core API or web app: AUD $35,000–$90,000. Enterprise system: $90,000–$200,000. Microservice platform: from $200,000. Fixed-scope quotes after free technical discovery.

Both. Azure for Microsoft-ecosystem clients. AWS (ECS, Lambda, Elastic Beanstalk) for AWS-first or multi-cloud clients. We do not force platform choice based on our preference.

Yes — we start with an assessment identifying breaking changes and Windows dependencies. Small-to-medium codebases take 8–20 weeks. We have done enough .NET migrations to know where the real risks are.

Yes where appropriate — CQRS with MediatR separates commands (write) from queries (read), enabling independent optimisation of each path. Most useful in systems with complex write logic and demanding read performance. We use it where it adds value, not universally.

xUnit as our primary test framework, FluentAssertions for readable assertions, Moq or NSubstitute for mocking, Respawn for database test cleanup, and NBomber for load testing. All tests run in CI — failing tests block deployment.

.NET Framework is Windows-only, legacy. .NET 8 is cross-platform, actively developed, and significantly faster — the correct choice for all new projects. If you are on .NET Framework, migration planning is important now.

ASP.NET Core REST API: 8–14 weeks. Enterprise web application: 16–28 weeks. .NET Framework to .NET 8 migration: 8–20 weeks depending on codebase size.

Entity Framework Core for standard data access with migrations. Dapper for performance-critical queries with complex SQL. We choose based on query requirements — not habit.

DDD is an approach to software design that models complex business domains through aggregates, value objects, domain events, and bounded contexts. We apply it where domain complexity justifies the overhead — and avoid it where a simpler CRUD model is appropriate.

Blazor lets you build web UIs in C# instead of JavaScript — server-side or WebAssembly. Right for teams that want to stay in the C# ecosystem for both backend and frontend. We use it for enterprise internal tools where the component model maps well to data-driven interfaces.

Yes — independently deployable NestJS services with Docker on ECS or AKS, their own databases, gRPC for service communication, and MassTransit for message-based async patterns. We design service boundaries thoughtfully and recommend microservices where complexity justifies them.
