FREELANCE SOFTWARE DEVELOPMENT
ASP.NET Core APIs built for the systems that have to depend on them.
I design and implement clear, secure API boundaries for business applications, internal tools and integrations—using ASP.NET Core, C# and practical operational discipline.
HOW I HELP
Make the next technical decision a useful one.
A useful API is more than a collection of endpoints. It has understandable resources, explicit validation, predictable errors, sensible authorization and a plan for integrations and background work. I use those concerns to shape the design before the route list becomes a contract.
- API design and implementationREST endpoints, request validation, response conventions and documentation that make integration less fragile.
- Integration and background workThird-party services, scheduled jobs, queues and data synchronization designed around failure and retries.
- Performance and diagnosisTracing slow paths across application code, database access and infrastructure constraints.
This service suits a new backend, an integration that must stop relying on manual exports, or an existing API that needs a careful technical review. Where a full workflow is involved, I connect the API work to the surrounding business software rather than treating it in isolation.
