Why RAG Architecture Matters

Confident vs. Correct — The Core Reason RAG Exists

Without RAG
Answers from general training data only
No way to verify or cite a source
Confidently wrong on company-specific facts
Can’t reflect anything added after training
With Production RAG
Answers retrieved from your real documents
Citations back to the exact source
Grounded in fact, evaluated for accuracy
Updated the moment your documents change
Our Process

Building a RAG Pipeline That Holds Up

1

Audit Your Data

What documents and sources actually need to be retrievable.

2

Design Retrieval

Chunking strategy, embeddings, and vector store matched to your content.

3

Build & Evaluate

Pipeline built and tested against real questions your users will ask.

4

Deploy & Monitor

Shipped with freshness handling and retrieval-quality monitoring.

What We Build

The Full RAG Pipeline, Skill by Skill

Document Chunking & Preprocessing

Splitting PDFs, wikis, and tickets into retrieval-friendly chunks that preserve meaning — the single biggest lever on answer quality.

Vector Database Architecture

Pinecone, Weaviate, or pgvector tuned for your scale, latency, and cost — chosen for your constraints, not ours.

Embedding & Retrieval Strategy

Semantic, hybrid, or re-ranked retrieval matched to your content type, not a one-size-fits-all default.

Evaluation & Hallucination Testing

Automated test suites that catch answers drifting from source material before your users do.

Industries

RAG Systems Built for Data-Heavy Industries

Confidentiality

Your Knowledge Base, Your Confidentiality

Your Documents Stay Yours

Source documents and embeddings live in infrastructure you control or approve — never used to train shared models.

NDA Before Discovery

Signed before any technical conversation touches your knowledge base or internal systems.

Common Mistakes When Hiring a RAG Developer

Hiring for LLM experience alone, without retrieval-specific skills
Skipping an evaluation plan — no way to measure if retrieval is actually accurate
Choosing a vector database before understanding your content type
Treating the knowledge base as static instead of planning for updates

Common Questions

Everything You Need to Know Before You Hire.

The questions we hear most from teams hiring a rag developer. Don't see yours? Ask us directly on the right.

A RAG developer specializes in retrieval-augmented generation — connecting large language models to your own data sources so answers are grounded in fact rather than only what the model learned during training. It’s a specific, technical subset of AI engineering: chunking, embeddings, vector search, and retrieval tuning.

That’s a classic sign of a language model answering from its general training instead of your actual data — the fix is a RAG pipeline that retrieves your real documents and forces the model to answer from that retrieved context, with citations back to source.

Practically anything text-based: PDFs, Word docs, Confluence or Notion wikis, support tickets, product catalogs, CRM notes, and structured database records. Each source type needs slightly different chunking and preprocessing.

A focused proof-of-concept against a defined document set typically takes two to four weeks; a production-grade system with freshness handling, evaluation, and monitoring is usually a longer, phased engagement.

It depends on your scale, existing infrastructure, and budget — Pinecone and Weaviate suit larger, managed deployments, while pgvector is a strong option if you already run PostgreSQL and want to avoid a new piece of infrastructure. We’ll recommend based on your actual constraints.

It significantly reduces it by grounding answers in retrieved facts, but no system eliminates hallucination entirely — we pair RAG with evaluation pipelines and confidence thresholds so uncertain answers are flagged rather than presented as fact.

Yes — we offer support retainers that include monitoring retrieval quality, re-indexing as your documents change, and tuning as usage patterns evolve.
