Why this page exists
Most boutique consulting practices sell "discovery + scope + custom build" engagements that start at $50K and take 3 months before the customer sees working code. DArnTech does the opposite — we surface the patterns that are already operating in our own stack and let you hire for the deployment + customization specifically. The discovery work is done. You're hiring for delivery.
Why we can do this: the engineering work has compounded across 7+ years of customer engagements (Eli Lilly, Biosero) and DArnTech's own infrastructure (3 RAG instances in production, multi-agent framework with pattern storage, RAG-as-a-product running in 4 consumer services, 19+ self-hosted services across 4 N2 nodes serving 5 family domestic users plus the consulting practice). When you hire DArnTech, you're hiring the practitioner who built and operates this stack — not a project-manager packaging someone else's engineering.
Built corpus: 3 production RAG instances (darntech-rag · dellatech-rag · governance-rag) on a shared rag-core codebase, each indexing ~10K+ documents with daily re-index timers. Reverse-proxied through nginx, deployed via rag-core-client v0.4 npm package across 4 consumer services (Casey Jr dashboard, Lorna deal-staleness detector, EllaBot entry-detail view, Casey-Jr laundry-room operational query). Pattern is operational, not aspirational.
RAG-as-a-Service deployment
$8K initial + $300/mo hosting · 2-3 week deploy
Stand up a dedicated RAG instance for your business on DArnTech infrastructure (or your cloud). We ingest your document corpus, configure retrieval, expose a query API, optionally bolt on a chat UI. You own the data, query the index via our managed endpoint or your own.
Knowledge-base RAG (your docs queryable)
$5K initial + $150/mo · 1-2 week deploy
Ingest your Confluence / Notion / BookStack / Google Drive / Slack export into a RAG index. Your team queries via Slack bot, web UI, or our chat client. Answers cite source documents. Eliminates "where did we document that" friction for ops + onboarding.
Customer-support RAG / embedded chatbot
$12K initial + $400/mo · 3-4 week deploy
Your help docs + product spec + FAQ into a RAG-powered chatbot embedded on your site. Customer asks "how do I X" → answer with source citations. Reduces support volume for known questions, routes unknown to a human.
Document-analysis RAG (contracts / proposals)
$8K initial + $200/mo · 2-3 week deploy
Ingest historical contracts, proposals, SoWs into a queryable index. Ask "what did we promise on similar deals" or "what redlines have we accepted from this customer." Cuts pre-deal research from hours to minutes for sales + legal teams.
Code-review RAG (your codebase trained)
$10K initial + $300/mo · 2-3 week deploy
For dev teams. Your codebase + commit history + PR comments + style guide into a RAG index. New devs query "how do we handle X in this codebase." Code-review assistance via the chat client. Faster onboarding, fewer style-guide deviations.
Compliance-monitor RAG
$15K initial + $500/mo · 3-5 week deploy
Ingest regulatory documents (FDA · OSHA · industry-specific) into a RAG. Daily change-detection alerts on new guidance affecting your product/operation. Critical for regulated verticals — life sciences, finance, construction with safety codes.
Sales-intelligence RAG
$8K initial + $250/mo · 2-3 week deploy
Customer-interaction history + CRM notes + past-deal context into a RAG. Sales rep prepping a call queries "what's the history with this account" and gets a synthesized prep brief in 30 seconds. Multiplies sales-team time.
Email-triage / summarizer
$6K initial + $150/mo · 1-2 week deploy
RAG over your inbox + saved correspondence + customer-context corpus. Auto-categorize incoming email, suggest replies, surface relevant prior-thread context. For founders/execs drowning in email.
Onboarding-doc RAG (internal ops)
$5K initial + $150/mo · 1-2 week deploy
Your runbooks + SOPs + tribal-knowledge interviews captured into a RAG. New hires query "how do we handle X" and get the answer faster than asking a senior. Reduces senior-team interruption, accelerates ramp.
Domain-vertical RAG packages
$15K-30K initial + $500-1500/mo · 4-8 week deploy
Pre-tuned RAG for specific verticals: legal-practice (case-law + your matter history), finance-firm (regulatory + your client history), construction-vertical (codes + your project history), lab-research (protocols + your data). Inherits domain ontology + retrieval tuning from prior deployments.
Built corpus: Sprite Forge (Express/TS · ComfyUI + Ollama · pgvector RAG · production image-generation pipeline), GBGreg (multi-agent AI · hybrid retrieval · pattern storage), Diller Queen (Godot + FastAPI · WebSocket multiplayer with server-authoritative game state), Nodemad (faster-whisper + Ollama + Piper voice pipeline · ESP32-S3 paired hardware). Cross-project pattern reuse compounds the deploy speed.
LLM integration consulting

Smaller stuff? We've got that too.
Not every business needs a $30K RAG deployment or lab-automation engagement. The same DArnTech infrastructure runs a small-business services line (Bookings, Analytics, Newsletter, etc.) at $19-79/mo per service. Same operator, same support model, smaller buyer profile.
