Freelance Search & Relevance Programmer: Tuning Elasticsearch, Fuzzy Part Matching & Hybrid Vector Search

Fast, accurate search directly drives e-commerce conversion, clinical EHR lookup speed, and AI RAG retrieval precision. As a Senior Freelance Search & Relevance Programmer, I design custom tokenizers, edge n-gram analyzers, real-time PostgreSQL-to-Elasticsearch CDC pipelines, and hybrid BM25 + semantic vector indexes.
