Professional profile
Senior Software Engineer with over 25 years of commercial experience, specialising in C#/.NET, Microsoft Azure, identity and application security, multi-tenant SaaS platforms and distributed systems. Experienced in software architecture, platform modernisation and the migration of business-critical legacy systems to modern cloud-hosted solutions.
I have led the development and consolidation of customer-facing platforms, designed secure authentication and identity solutions, and worked with sensitive financial, healthcare and payroll systems. I am a strong advocate of Test-Driven Development, SOLID design principles and clean, maintainable code, and enjoy mentoring developers and sharing knowledge within engineering teams.
I use AI-assisted development where it adds value, including GitHub Copilot within Visual Studio and .NET development workflows. I have used repository-level instructions to align generated code with established coding standards, SOLID principles and unit-testing practices, while retaining developer review of generated changes.
