API and Backend Integration

Building and connecting backend services, APIs, databases and external systems.

Capability statement

Alex OS and this CMS are two separate services talking over HTTP with an internal auth secret — a concrete example of the service-boundary discipline I aim for.

Problems I solve

  • Connecting frontend applications to backend services
  • Integrating AI APIs
  • Designing reusable API contracts
  • Handling authentication and permissions
  • Connecting CMS content to AI services

Approach

  • Define explicit contracts
  • Validate inputs and outputs
  • Keep service boundaries clear
  • Avoid leaking provider-specific logic throughout the application
  • Keep configuration outside source code

Full description

I work with application backends and service integrations, especially where a frontend, CMS, AI reasoning layer and external APIs need to cooperate. I focus on clear interfaces, reusable services, validation, authentication and reliable data flow.
Evidence standard

Strengths

  • Two independently deployable services (CMS + Alex OS) with a clean HTTP contract between them
  • JWT-authenticated CMS sessions and internal-secret-authenticated service-to-service calls
