AI Engineering

AI systems with engineering discipline.

My focus is not simply calling an LLM API. I work on the retrieval, indexing, latency, caching and evaluation layers that make AI applications useful in production.

BM25 Vector Search Qdrant Elasticsearch Cross Encoder RAG Embeddings LangChain
Hybrid Retrieval BM25 + dense vector retrieval for stronger recall
Reranking Cross-Encoder based relevance scoring
Production RAG Chunking, embeddings, caching and source citations
LLM Orchestration Structured outputs, constrained prompting and hallucination mitigation
