LLM evaluation & AI quality

Your LLM feature, under real evaluation.

Golden datasets, LLM-as-judge scoring, and safety runners — hallucination, injection, toxicity, PII — wired into your CI. A prompt change that makes things worse stops at the gate, not in production.

what you get

Golden dataset + judge

50–200 real inputs with agreed-good outputs, versioned next to the code; LLM-as-judge scoring for faithfulness, relevance, and safety.

Safety runner battery

Hallucination, jailbreak, prompt-injection, toxicity, PII-leak, refusal, bias, consistency — plus cost and latency budgets.

CI quality gate

The suite runs on every PR. A score below the ratcheted floor blocks the merge — with a scorecard your PM can read.

Runbook + handoff

Your team extends the golden set and owns the gate without me.

how we work together
Eval Audit
~1 week · scoped & quoted

I map where your LLM feature can fail, score your current coverage against the failure modes that matter, and hand you a prioritized plan you own. The fastest way to a concrete quote.

Minimum Viable Gate
~2 weeks · scoped & quoted

30–50 golden traces, one judge, one CI step that can block a merge. The regression you currently can't see, caught this month.

Full Eval Battery
~4–8 weeks · scoped & quoted

Safety runners, ratcheting floors, RAG retrieval metrics, cost budgets, runbook and handoff — the complete quality system, owned by your team.

questions
Which tools do you use?

Promptfoo and DeepEval where they fit, custom runners where they don't. The tool matters less than the discipline: computed scores from real commands, never opinions.

Our feature uses RAG — does that change the approach?

It adds retrieval-quality evals (context precision/recall, citation coverage) in front of the generation evals. I've shipped RAG systems where 100% of answers carry citations by design.

How long until we have a working gate?

A minimal gate — 30 golden traces and one faithfulness judge in CI — typically lands in the first two weeks. The battery grows from there.

30 minutes. Bring the feature that scares you.

You leave with a concrete plan either way — the call is free and the plan is yours.
