.NET 8 Development Services
Enterprise-grade .NET 8 and ASP.NET Core applications — from healthcare interoperability platforms to cloud-native microservices and high-performance APIs.
The Challenge
Senior .NET Developers Are Rare — Domain-Specialist Ones Are Rarer
Any developer can write C# code that works in a demo environment. Building a .NET 8 system that processes millions of healthcare transactions daily, maintains sub-100ms API response times under load, handles EHR integration edge cases without data loss, and stays maintainable across years of changing requirements — that demands something beyond language fluency. Healthcare and enterprise .NET development is a specialised discipline. Compliance requirements (HIPAA, CMS mandates) shape architecture decisions. Data integrity demands idempotent operations and robust transaction handling. Audit trails and observability are regulatory requirements, not optional enhancements. The UAE and KSA enterprise markets add their own layers: DHA and DOH compliance for healthcare software, Arabic locale handling for government systems, and Azure governance requirements that differ from US deployments. I have built and led .NET systems at this level across healthcare, logistics, CRM, and fintech — most recently architecting the FHIR R4 data platform at Octdaily that connects 20,000+ US Skilled Nursing Facilities. I write .NET code that your team will be proud to maintain three years from now.
Deliverables
.NET Development Capabilities
- .NET 8 and ASP.NET Core Web API development — RESTful services, minimal APIs, versioned endpoints, OpenAPI/Swagger documentation, and HATEOAS where appropriate
- Clean Architecture and Domain-Driven Design (DDD) — bounded contexts, aggregate roots, domain events, repository pattern, and dependency inversion — systems that stay coherent as they grow
- CQRS and MediatR patterns — separate read and write models, command/query separation, and pipeline behaviours for cross-cutting concerns (logging, validation, caching)
- Microservices architecture on Azure Kubernetes Service — service decomposition, inter-service communication (gRPC, Service Bus, Event Hubs), sidecar patterns, and distributed tracing
- Entity Framework Core optimisation — query performance tuning, strategic eager/lazy loading, compiled queries, shadow properties, and database migration strategies for zero-downtime deployments
- Real-time applications with SignalR — bidirectional communication for dashboards, notifications, and collaborative features — scaling to thousands of concurrent connections with Azure SignalR Service
- Background processing with Hosted Services and Azure Functions — reliable job queues, recurring tasks, event-driven processing with at-least-once delivery semantics
- Authentication and authorisation with Azure AD / Entra ID and MSAL — role-based access control, claims transformation, API-to-API authentication with managed identities
- Comprehensive testing — unit tests with xUnit and Moq, integration tests with TestContainers (real databases, real dependencies), and architecture fitness functions with ArchUnitNET
- CI/CD pipelines with Azure DevOps and GitHub Actions — automated build, test, security scanning, container image builds, and progressive deployment (blue/green, canary releases)
- Performance profiling and optimisation — identify hot paths with Application Insights, database query analysis, memory allocation profiling, and async/await anti-pattern elimination
- Legacy .NET Framework to .NET 8 migration — Strangler Fig pattern for large codebases, dependency modernisation, and incremental migration with zero production disruption

Process
How I Work
A clear, predictable engagement model with no surprises.
Domain & Requirements Deep-Dive
Understanding your business domain thoroughly before designing the system. I ask about user workflows, data volumes, regulatory constraints, integration points, and team structure — because all of these shape the right architecture. Output: a requirements document that exposes hidden complexity before it becomes a mid-project surprise.
Architecture Design & ADR
Design the system architecture — bounded contexts, service boundaries, data model, API contracts, infrastructure topology. Produce Architecture Decision Records (ADRs) explaining why each significant decision was made. This documentation pays dividends when the team grows or requirements change in year two.
Iterative Development — Working Software Every Sprint
Two-week sprints. Every sprint ends with deployed, tested, working software — not just code checked into a branch. Test coverage is built from the start. Sprint reviews with your stakeholders every fortnight ensure we stay aligned with business value.
Code Review & Engineering Standards
Every pull request reviewed before merging. Code style enforced via .editorconfig and StyleCop. Static analysis with SonarCloud. Security scanning with GitHub Advanced Security. The codebase has consistent style and quality from the first commit to the last.
Performance Validation
Benchmark critical paths against SLA targets before going to production. Load test with k6 or NBomber. Profile memory and CPU under load. Address N+1 queries, synchronous over async calls, and unnecessary allocations. Production should not be the first time you discover a performance problem.
Handover & Knowledge Transfer
Full codebase documentation, runbooks for operations, architecture diagrams kept updated. Handover sessions with your engineering team — walking through every significant design decision so they can maintain and extend the system confidently. Your team owns the code; I make sure they understand it.
