Modernising complex systems

I help untangle existing systems and plan manageable steps towards a simpler architecture, staying involved through implementation.

Distributed systems & cloud integration

I design distributed systems and integrations using domain-driven design, Azure, AWS, and .NET, with clear service boundaries and reliable communication.

From business needs to working software

I connect business capabilities, processes, and requirements to practical solution design, helping teams make decisions and carry them through delivery.

I designed cloud solutions for fleet operations, rental, and repair, maintenance and tyre services, using .NET microservices on AWS. My work included API integration, workflow orchestration with PEGA, and leading legacy data migration to AWS.
