API Design & Integration

RESTful services, third-party integrations, adding new APIs to existing systems, and API-first architecture consulting.

The vast majority of software systems today have to talk to one another. When these integration points are not well designed, they become the most fragile part of the system.

What kinds of projects do I build?

  • RESTful API design and development from scratch
  • Exposing a legacy system through an API (facade / anti-corruption layer)
  • ERP, accounting and shipping-company integrations
  • Setting up a webhook system and event-driven architecture
  • API Gateway setup and rate-limiting policies
  • Third-party OAuth2 integrations (Google, Microsoft, custom IdP)

Technical preferences

  • .NET 8 Web API
  • MediatR + CQRS pattern
  • Input validation with FluentValidation
  • Swagger / OpenAPI 3.0 documentation
  • JWT + API Key authentication
  • Response cache and distributed lock with Redis
