Senior .NET and Azure development
for UK organisations.
I help organisations modernise legacy applications, migrate to Azure, set up DevOps pipelines, and develop web applications and APIs.
Services That Deliver Results
From cloud migrations to ground-up builds, I bring enterprise-grade thinking to every project — no matter the size.
Azure Cloud Migration
Plan and deliver phased Azure migrations with agreed cutover and recovery arrangements. Infrastructure-as-code, cost review, and security configuration.
.NET Application Development
Custom web applications, APIs, and microservices built with C#, ASP.NET Core, and Entity Framework. Clean architecture, tested code.
DevOps & CI/CD Setup
Azure DevOps pipelines, automated testing, infrastructure-as-code with Terraform/Bicep, and deployment automation to reduce manual release work.
Legacy Modernisation
Upgrade aging .NET Framework apps to .NET 8+, refactor monoliths, and eliminate technical debt holding your team back.
Team Augmentation
Embed into your existing team as a senior developer or tech lead. Sprint planning, code reviews, mentoring, and hands-on delivery.
API & Integration Development
RESTful APIs, third-party integrations, data pipelines, and system interconnection. Built for reliability and scale.
Tools I Work With Daily
Microsoft ecosystem expert with deep experience across the full Azure platform. Open to working with other stacks when the project calls for it.
From Brief to Delivery
A structured process that keeps you informed and your project on track. No surprises, no scope creep.
Discovery Call
Free 30-minute call to understand your project, constraints, and goals. I'll tell you honestly if I'm the right fit.
Proposal & Scope
Detailed proposal with clear deliverables, timeline, and fixed or time-and-materials pricing. No hidden costs.
Build & Iterate
Agile delivery in 1-2 week sprints with regular demos. You see progress continuously, not just at the end.
Deliver & Support
Thorough handover with documentation, knowledge transfer, and a 30-day defect correction period for bugs directly attributable to the delivered work.
