Notes on data engineering, PostgreSQL at scale, and building self-hosted AI/RAG infrastructure — written as I ship things.
A packaged hospital information system built around how Kenyan hospitals actually operate — SHA claims, M-Pesa billing, USSD access for feature phones, and one patient record from registration to discharge.
Social surveillance promises order and safety, but a society that outsources moral reasoning to cameras and algorithms doesn't become more virtuous — it becomes blind. On the compliant citizen surveillance manufactures, and the conscience it never has to build.
A plain-language look at the real problem behind Sheria Platform — Kenya's court backlog and slow legal research — and what its four modules (Ask, Digitize, Verify, Predict) actually do today.
A structural tour of Sheria Platform — three LangGraph graphs, the scraper-to-Qdrant/Neo4j ingestion pipeline, the Next.js proxy pattern, and two different Ollama deployment topologies.
How Sheria's Qdrant-backed semantic cache cuts repeated LLM calls for Kenyan legal queries — the real design and a triple-embedding fix.
Why plain vector search isn't enough for legal research, and how a LangGraph agentic pipeline with a Neo4j citation graph and self-hosted inference makes case-law retrieval traceable and fast.
