About

Professional summary

I am a Senior .NET Full-Stack Developer with more than nine years of commercial experience building, modernising, and supporting business-critical applications. My core strengths are C#, .NET, ASP.NET Core, Angular, SQL-based systems, and Microsoft Azure.

I design scalable backend services, REST APIs, system integrations, and event-driven solutions. I have hands-on experience delivering cloud services using Azure Functions, Service Bus, App Service, Logic Apps, and related Azure infrastructure.

I work across the full delivery lifecycle, from database design and backend architecture to Angular user interfaces, production troubleshooting, and performance optimisation. I am comfortable with both modern platforms and legacy environments, including VB6 application replacement and migration.

In my current role, I contribute to a large fleet-management platform serving over 200,000 vehicles and 1,100 customers. My work includes telematics, reporting, driver scoring, risk assessment, ePOD workflows, and AngularJS-to-Angular modernisation.

I have delivered web applications used across multiple countries and manufacturing sites, while also providing technical support, code reviews, debugging, and CI/CD practices. I value reliable, maintainable solutions and use AI-assisted development tools such as GitHub Copilot to improve delivery efficiency.
