LLM Product Development

Ship AI features inside your SaaS — with evals, guardrails, and cost control.

Design and ship user-facing AI features — copilots, generators, semantic search — with eval harnesses, safety, and cost dashboards.

3–8 weeks Build engagement Docs & handoff included

Problems I solve

  • AI feature demoed well but broke in prod
  • Costs unpredictable, no per-customer attribution
  • No way to tell if a prompt change made things worse
  • Safety incidents from ungrounded outputs

What you get

  • Feature scoping tied to a measurable eval
  • Prompt + model versioning with A/B evals
  • Streaming UX with cost + latency SLOs
  • Content safety, PII redaction, and audit logs

Use cases

In-app AI copilot

Chat-with-your-data copilot inside a SaaS with tool calls scoped to the tenant.

Structured output generators

Generate emails, contracts, or reports with schema-validated outputs.

Semantic search + summarize

Hybrid search across docs with grounded summaries and citations.

AI classifier at scale

Fine-tuned small model + LLM fallback for cost-efficient classification.

Case study

LegalTechVertical SaaS · Legal

Challenge

AI drafting feature had 22% hallucination rate on citations and cost was untracked per customer.

Approach

  • Introduced a 300-case golden eval + CI gate
  • Added retrieval + citation-required prompting
  • Per-tenant cost tracking with hard caps
  • Model routing: Haiku for drafts, Sonnet for finals

How I work

  1. 1

    Scoping + eval design

    Define success metric, build a small golden dataset first.

  2. 2

    Prototype

    Ship a thin end-to-end slice against real inputs.

  3. 3

    Harden

    Guardrails, retries, structured outputs, cost caps.

  4. 4

    Ship + observe

    Streaming UX, telemetry, per-tenant cost.

Deliverables

  • Production AI feature integrated in your app
  • Eval harness + CI gate
  • Cost & latency dashboards
  • Prompt + model version registry

Benefits

  • AI features that survive real users
  • Predictable unit economics
  • Confidence to iterate prompts

Frequently asked questions

Do you work inside our existing codebase?+

Yes — TypeScript/Python most commonly. I can PR into your repo or ship a standalone service you consume.

How do you handle evals?+

A golden dataset per feature + Braintrust/Langfuse for online eval, gated in CI before any prompt or model change.
