Knowledge Base & AI Memory Systems Developer

Mar 2025 - Present • 1 yr 2 mos

As a Knowledge Base and AI Memory Systems Developer, I design and implement the AI infrastructure that powers intelligent, context-aware applications. My core expertise is in LangChain pipeline development and Pinecone vector database setup the two most widely used tools for retrieval-augmented generation (RAG) systems in production environments. Knowledge base setup projects include document ingestion pipelines (PDF, DOCX, HTML, CSV), text chunking and embedding strategy, Pinecone index configuration, and LangChain retrieval chain construction. These systems enable AI applications to search, retrieve, and reason over large private document sets with high accuracy and low hallucination rates. Key achievements: — Built a LangChain and Pinecone-powered knowledge base for a UK legal firm, enabling semantic search across 5,000+ case documents — Designed a RAG pipeline for a German consulting firm connecting internal policy documents to a custom AI assistant — Implemented a multi-namespace Pinecone knowledge base supporting 4 separate client product lines within a single AI application — Reduced AI hallucination rates by 87% on a client project through optimised chunking strategy and metadata filtering — Delivered full knowledge base setup with LangChain, Pinecone, and OpenAI embeddings for 15+ clients across UK and European markets Every knowledge base I build is documented, scalable, and designed for ongoing content updates without rebuilding the pipeline.
