TravelUp

Software Engineer · May 2024 to Present · Reading, UK

Built a .NET 10 MCP server exposing TravelUp's GDS and NDC integrations through a generic internal API, giving AI assistants live flight data and an inline TypeScript widget, creating a channel outside aggregators such as Skyscanner.
Built the backend for the customer-facing booking management system from the ground up in .NET 10, owning it end to end from data model to API contract, with xUnit tests and integration tests against a real test database. Now serves 10,000+ booking retrievals per day.
Migrated a legacy WCF-based GDS monolith to .NET 10 microservices following Clean Architecture, deployed on Azure App Service through Azure DevOps CI/CD.
Built versioned REST APIs integrating 5+ airline NDC providers behind a common internal interface so new providers could be onboarded without changes to consuming services.
