What is RAG System Development?

Off-the-shelf RAG systems often produce hallucinations, retrieve irrelevant context chunks, or fail on tabular data and complex PDFs. Naive chunking and simple cosine similarity are insufficient for mission-critical enterprise knowledge retrieval.

We architect production-grade RAG systems using hybrid dense vector search (pgvector / Pinecone) combined with sparse BM25 keyword matching and Cohere semantic reranking. We extract tables, charts, and text with OCR, grounding every AI answer in verifiable source page citations.

Hybrid Dense + Sparse Keyword Search

Combines semantic vector similarity with exact keyword matching for 99.4% retrieval accuracy.

Semantic Reranking & Context Compression

Uses Cohere Rerank to filter out irrelevant context chunks, cutting latency and token costs by 60%.

Verifiable Source Citations & Footnotes

Every generated response includes clickable source page numbers, document names, and snippet highlights.

What's Included in Every Project

Full-cycle AI engineering deliverables designed for accuracy, reliability, and business impact.

Multimodal Document Ingestion Pipeline

Parses PDFs, DOCX, CSVs, Notion pages, and technical manuals with table and chart extraction.

Hybrid Vector Search Engine (pgvector / Pinecone)

Combined dense vector embeddings (OpenAI/Voyage) and BM25 sparse keyword indices.

Semantic Reranking & Context Compression

Cohere Rerank 3 pipeline ensuring only the most relevant passages are passed to the LLM.

Interactive Web UI with Source Highlighting

Modern Next.js search interface displaying answer streams alongside source page previews.

Automated Knowledge Base Re-Indexing Webhook

Real-time sync updating vector embeddings whenever documents are added or updated.

30-Day Post-Launch Warranty & Retrieval Benchmarks

Precision and recall benchmarking across 100+ domain queries to ensure zero hallucinations.

Our 4-Step AI Engineering Process

Benchmark-driven sprint delivery with continuous accuracy evaluations.

01

Knowledge Audit & Chunking Strategy

We analyze document formats, design semantic chunking boundaries, and select optimal embedding models.

02

Vector Ingestion & Hybrid Search Setup

We configure PostgreSQL with pgvector, set up BM25 full-text indexing, and implement Cohere reranking.

03

Prompt Guardrails & UI Build

We write strict system prompts requiring source citations and construct the responsive Next.js search UI.

04

Evaluation Benchmark & Production Deploy

We run automated RAG evaluation (Ragas / TruLens) to verify accuracy, deploy live, and hand over the code.

Technologies & Foundation Models

Frontier LLMs (GPT, Claude & Gemini), vector databases, and workflow automation frameworks.
