Lumen AI

Lumen AI is a TypeScript-based platform that integrates large language model capabilities into an end-to-end product experience. The system is designed around structured AI pipelines that take raw user input, apply prompt engineering and model orchestration, and return actionable outputs with high reliability.

The architecture separates concerns cleanly: a type-safe API layer handles input validation and request routing, while the AI layer manages prompt templates, context injection, and response parsing. This allows rapid iteration on model behaviour without touching the API surface.

Built with performance and maintainability in mind, the codebase uses TypeScript throughout to enforce contracts between modules and catch integration errors at compile time — particularly important when model outputs must conform to specific downstream schemas.
