Flipped.ai — Production AI Systems
An engineering case study of the production AI behind an AI-native recruitment platform: document intelligence, multilingual/Arabic OCR, hybrid RAG retrieval, semantic candidate matching, and open-weight LLM serving with vLLM behind async, distributed microservices.
Engineering Highlights
- Document-intelligence pipeline for messy, multilingual CVs; custom Arabic OCR/extraction (~80% → 95%+ parsing accuracy)
- Hybrid retrieval (BM25 + dense) with reranking and MMR for semantic candidate matching
- Open-weight LLM serving with vLLM — continuous batching, PagedAttention, KV-cache management
- Async FastAPI + Celery/RabbitMQ/Lambda microservices with ATS integrations (Zoho Recruit, Greenhouse)
