Case Study
Bible Verse — Case Study
Production SaaS Platform · Full-Stack · Founder & Sole Engineer
A domain-driven SaaS platform with five independently scalable system boundaries: scripture content delivery, RAG-backed AI study, real-time community interaction, async media processing, and infrastructure services — built and operated end-to-end.

How We Built It
- RAG pipeline grounding AI responses in actual scripture rather than model memory
- Hybrid Llama / OpenAI routing — local inference for cost, API fallback for quality at the edge
- Non-blocking media processing — FFmpeg jobs enqueued via BullMQ, API never waits on transcoding
- Cross-instance real-time consistency via Redis pub/sub behind WebSocket and WebRTC layers
Lessons Learned
- Domain boundaries enforced at the service layer prevent coupling long before scale demands microservices.
- RAG retrieval quality matters more than model size — better embeddings outperform a larger model on poor context.
- Async queue design should be first-class, not bolted on; BullMQ worker isolation saved the request path repeatedly.
