Card issuance, transaction processing and lifecycle management; integrations with payment providers such as FIS and Elavon for balance enquiries, tokenisation and real-time transaction retrieval.
Migrate legacy .NET / VB.NET / Web Forms estates into modern, cloud-native architectures — incrementally, without stopping the business that depends on them.
Team leadership, mentoring and delivery ownership for engineering teams working in regulated, high-stakes environments — from story breakdown through to production.
Built the card issuance and transaction processing platform powering onboarding, top-ups and spend controls, integrated with FIS and Elavon for real-time balance and token services.
Modernised legacy B2B .NET applications into Node.js/TypeScript microservices in Azure; led a development team through story creation, delivery and DoD reviews.
Engineered payment and settlement REST APIs on Cosmos DB and Azure Functions; CI/CD pipelines with Sonar Cloud & SOOS cut deployment errors by 30%.
Built and maintained billing, settlement and workflow systems in C#, VB.NET and ASP.NET Core across a multi-year change programme.
