Production LLM systems. Not chatbots.

We build LLM-powered software that goes into production and stays there — structured outputs, validated schemas, observable pipelines, real cost controls.

Most teams ship LLM demos. We ship LLM systems. Lead qualification that classifies prospects into warm / lukewarm / cold from long-form content. Document extraction with audit trails. Decision-support workflows with human-in-the-loop fallbacks. The chat window, where it exists at all, is a fallback — not the product.

What we actually build

The reference architecture

Input
user record + content URLs
Fetch & clean
bounded token budget
Prompt assembly
rubric + schema + few-shot
Claude API
pinned model + low temp
Pydantic validation
strict schema check
invalid
Retry once
fix-it prompt
still invalid
Human review queue
never silently coerced
valid
Postgres
verdict + reasoning + audit metadata
n8n orchestration
CRM sync, retries, notifications
An LLM call is one node in a pipeline. Schemas, retries, audit, and orchestration are the rest.

How an LLM feature actually ships

Every LLM call we put into production runs through the same scaffolding. The model is one node in a pipeline that mostly looks like normal software.

  1. 01

    Inputs are normalized and bounded

    We fetch, clean, and trim inputs to known token budgets. Cost and behavior are predictable before the model ever runs.

  2. 02

    Prompt is assembled deterministically

    Rubric, schema definition, and few-shot examples are composed from versioned config — not free text living in an SDK file somewhere.

  3. 03

    Model call with pinned versions

    Anthropic Claude with model version pinned and temperature low. Same input produces the same output, modulo controlled stochasticity.

  4. 04

    Output is schema-validated

    Pydantic validates every response. Invalid output gets one fix-it retry; still invalid goes to a human review queue. It never silently coerces.

  5. 05

    Audit trail to Postgres

    Verdict, reasoning, source excerpts, model version, prompt version, and timestamp are written for every call. Reproducible, defensible.

  6. 06

    Orchestration via n8n

    Scheduling, retries, CRM sync, and human-fallback notifications all live in n8n. The LLM is one node in a workflow.

What we explicitly don't do

We get asked about these often. We say no on purpose.

Chatbots as the product

Chat dumps the cognitive load on the user and the reliability burden on the model. We use chat only as a fallback for ambiguous cases.

Fine-tuning for tasks Claude already does well

A well-engineered prompt with few-shot examples almost always beats fine-tuning on cost, iteration speed, and maintainability.

RAG for the sake of RAG

Most "chat-with-your-docs" projects don't need RAG. They need extraction, classification, or a normal search index with a small LLM layer on top.

Free-form text outputs in pipelines

If a downstream system has to parse what the LLM said, the parse will eventually break. Schemas are the contract.

"An LLM that returns free-form text is a bug surface. We make schemas the contract, validate every output, and route failures to humans. If your AI feature can't be unit tested, it isn't a feature yet."
