I develop APIs and integrations that connect applications with the information they need. Projects can include customer and order workflows, third-party services, mobile backends, and existing business systems, with validation, access controls, and maintainable .NET services.
Typical Integration Work
Customer and order workflows
APIs that let web and mobile applications read and update business records through validated services.
Third-party services
Connecting payment, messaging, and other external services your application depends on.
Existing ERP and CRM systems
Integrating through the APIs and application services a system already provides, after reviewing what it supports.
Mobile backends
ASP.NET Core APIs that serve mobile apps with the same rules as your web application.
What I Put in Place
REST API design with ASP.NET Core
Clear endpoints and contracts, documented with Swagger / OpenAPI.
Authentication and authorisation
Token or cookie-based authentication, with role and ownership checks enforced on the server.
Validation and error handling
Input is validated at the boundary and failures return useful, consistent responses.
Maintainable services
Business logic lives in testable .NET services, with Entity Framework Core for data access; separate services are introduced only where they genuinely help.
APIs and AI
Ordinary API integration is not AI, but well-structured, permission-aware APIs are what make safe AI tools possible. If you are considering an assistant later, see AI integration for existing applications.
