Overview
The WriterIX AI Pipeline is a standalone FastAPI microservice that handles all AI-driven content generation for the WriterIX platform. It exposes HMAC-secured endpoints that trigger Celery task chains for blog post generation: topic research, outline creation, section writing, SEO metadata, and featured-image selection. LLM calls use Gemini as the primary model with Groq as a fallback, with structured Pydantic output parsing for reliable results.
Responsibilities
- Designed the Celery task-chain architecture for multi-step blog generation
- Integrated Gemini (primary) and Groq (fallback) LLMs with structured Pydantic output parsing
- Implemented HMAC key verification and secure webhook callbacks to Laravel
Highlights
- Multi-step LLM pipeline with Gemini/Groq failover
- Typed event broadcasting for live progress in the dashboard
