What I Offer

Contracting Services

Senior-level engineering and architecture services available for fixed-term or rolling contracts across the UK.

Service 01

.NET Development

Expert .NET application development targeting the latest LTS and current releases — .NET 6 through .NET 9. I deliver robust, testable, and maintainable backend services using ASP.NET Core Web API, Worker Services, gRPC, and SignalR.

All code is written with Clean Architecture in mind: separated concerns, dependency inversion, and domain models that are independent of framework concerns — making your codebase easy to evolve and test.

ASP.NET Core .NET 6/7/8/9 Web API Entity Framework Core LINQ Worker Services gRPC Minimal APIs
Typical Deliverables
  • RESTful and gRPC API design & implementation
  • Domain model & business logic layers
  • EF Core database migrations & query optimisation
  • Background processing with Hosted Services
  • Integration with third-party APIs & services
  • Unit & integration test suites (xUnit / NUnit)
  • BDD specifications with SpecFlow
  • Code review, refactoring & modernisation

Service 02

C# Development

Deep C# expertise accumulated across 18+ years of professional development. From advanced generics and expression trees to modern features like records, pattern matching, nullable reference types, and primary constructors — I write idiomatic, modern C# that your team will want to maintain.

Experienced in applying SOLID principles, DRY, and Clean Code practices — ensuring codebases remain understandable, extensible, and testable as they grow.

C# 10/11/12/13 SOLID Principles DDD Design Patterns Async / Await Records & Structs Source Generators
Typical Deliverables
  • Domain model design with rich aggregates
  • Application service & command/query handlers
  • Generic repository & specification patterns
  • Pipeline behaviours & cross-cutting concerns
  • Custom middleware & filters
  • Library & NuGet package authoring
  • Legacy codebase audit & modernisation

Service 03

Cloud Infrastructure Development

Infrastructure as Code (IaC) using Terraform and Bicep to provision and manage Azure environments consistently across dev, staging, and production. Every resource is version-controlled, peer-reviewed, and deployed through automated pipelines — no manual portal changes.

Comfortable working with complex hub-spoke networking, Private Endpoints, managed identities, RBAC, and Azure Policy to ensure security and governance are baked in from day one.

Terraform Bicep Azure Resource Manager Virtual Networks Private Endpoints Managed Identity Azure Policy RBAC
Typical Deliverables
  • Terraform modules for Azure landing zones
  • Multi-environment infrastructure pipelines
  • Network topology & security group design
  • Key Vault, secrets, and certificate management
  • Azure Monitor, Log Analytics workspace setup
  • Cost optimisation & tagging strategy
  • Disaster recovery & backup configurations

Service 04

Cloud Architecture

End-to-end solution architecture for greenfield cloud-native platforms and brownfield modernisation programmes. I work with your teams to decompose monoliths into microservices, design event-driven integrations, and produce architecture decision records (ADRs) that stand the test of time.

Experienced across CQRS, Event Sourcing, Saga orchestration, API Gateway patterns, and service mesh with Istio — bringing proven patterns to your platform challenges.

Microservices CQRS Event Sourcing DDD Clean Architecture Saga Pattern API Gateway Istio Service Mesh
Typical Deliverables
  • Solution architecture & C4 diagrams
  • Architecture Decision Records (ADRs)
  • Domain decomposition workshops
  • Event storming facilitation
  • Non-functional requirements & SLA design
  • Multi-region & HA topology design
  • Technology selection & trade-off analysis

Service 05

Azure Development

Hands-on development using the full breadth of Azure PaaS and compute services. I build applications that leverage Azure-native capabilities — from serverless Functions and durable workflows to containerised workloads on AKS.

Deep experience with Azure Service Bus for reliable messaging, Cosmos DB for globally distributed data, and Application Insights for end-to-end observability — delivering production-ready systems your operations team can confidently manage.

App Services Azure Functions AKS Service Bus Cosmos DB Key Vault Storage Accounts Application Insights API Management Event Grid
Typical Deliverables
  • Azure-native application design & build
  • Event-driven integration with Service Bus
  • Serverless function apps & durable functions
  • Cosmos DB data modelling & indexing strategy
  • Azure AD B2C / Entra ID integration
  • Distributed tracing & alerting setup
  • Performance tuning & cost optimisation

Service 06

Azure DevOps & GitFlow Pipelines

Comprehensive CI/CD pipeline design and implementation using Azure DevOps YAML pipelines. From build validation through to multi-stage deployments with approval gates, environment-specific configurations, and rollback strategies.

I implement GitFlow and trunk-based branching strategies, integrate automated testing and security scanning, and configure Helm-based Kubernetes deployments — giving your teams fast, safe, and repeatable releases.

Azure DevOps YAML Pipelines GitFlow Helm Kubernetes Deployments GitHub Actions SonarQube OWASP ZAP
Typical Deliverables
  • Multi-stage YAML pipeline templates
  • Reusable pipeline template libraries
  • Git branching strategy & policy configuration
