API and Backend Integration

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

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
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

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.

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.

Explore with Alex OS

Alex builds backend integrations where the boundary between services is explicit, authenticated, and survives independent deployment.

API & Backend Integration

Alex works across the full integration stack — connecting frontends, CMSes, databases, AI reasoning layers, and external APIs. The focus is on clear contracts, validated data flow, and authentication that doesn't leak implementation details across service boundaries.

How Alex approaches integration work

Concrete example: Alex CMS ↔ Alex OS

Alex CMS and Alex OS are two independently deployable services — Next.js and FastAPI respectively — communicating over HTTP with an internal auth secret. CMS sessions use JWT authentication; service-to-service calls use a separate internal secret. Neither service assumes it owns the other's internals. This is the same boundary discipline Alex applies to client integration work. One practical consequence: a direct database write (a seed script, a manual insert) won't automatically surface in Alex OS — a deliberate reindex call is required, because the contract is HTTP, not shared state.

Why service boundaries matter in AI-integrated systems

When a frontend, CMS, and AI reasoning layer all need to cooperate, the failure mode is usually implicit coupling — the frontend knows too much about the AI provider, or the CMS leaks database structure into the API response. Alex OS sits between the CMS and the public site specifically to contain that complexity: it handles retrieval and reasoning without exposing those mechanics upstream or downstream.
