AI Integration.

AI features that ship. Not demos.

LLM features, agents and automation built into your product. From retrieval to tool calling. Built by someone who works AI-native every day.

(01) / Agent Run

Automation that does real work. With a human where it counts.

done1 edge case in the review queue, as designed

Edge cases route to people. That is the design, not a failure.

(02) / Building Blocks

Six pieces. Assembled for your product.

01

Retrieval

Answers grounded in your data, with sources. Not model guesswork.

02

Agents & tools

LLMs that call your systems. Read, decide, act, report back.

03

Structured output

Validated JSON your backend can trust. Retries on mismatch.

04

Evals

Quality measured on real cases. Before launch and on every change.

05

Streaming UX

Responses that feel instant. Loading states designed, not ignored.

06

Cost control

Model tiers, caching, budgets per feature. No surprise token bill.

(03) / What You Get

Deliverables. Shipped, not sketched.

  • LLM features inside your product. Chat, search, extraction, summaries.
  • Retrieval pipelines over your own data. Grounded answers, cited sources.
  • Agent workflows with tool calling. Automation that does real work.
  • Provider-agnostic setup. Anthropic, OpenAI or local models behind one interface.
  • Evals and guardrails. You know how it behaves before your users do.
(04) / Differently

What I do differently. AI-native, product first.

  • 01
    I work AI-native every day. This is my own workflow, not a trend I read about.
  • 02
    Product first. The model serves the feature, never the other way around.
  • 03
    Cost and latency budgets per feature. The token bill stays predictable.
  • 04
    No demo-ware. Every integration ships with error states and fallbacks.
(05) / Guarantee

What I guarantee. In writing.

  • 01
    Working features in production, not a slide deck.
  • 02
    Measured quality. Evals run before and after every change.
  • 03
    Full source, prompts and pipelines. You own everything.
  • 04
    30 days of free fixes after launch.
(06) / Why Me

Why me. Judgment over hype.

  • 01
    Senior engineer, ten years shipping. AI-augmented on every step.
  • 02
    I run LLMs in my own products. I know where they break.
  • 03
    One person from data to UX. No handoff between an AI team and devs.
  • 04
    You get engineering judgment, not hype.
(07) / In Your Team

Also available embedded. Your team, this discipline.

Not every project needs the full chain. If you run your own team, I join it in exactly this discipline. As a freelancer, inside your workflow.

  • 01
    AI engineer in your product team. LLM features, agents, pipelines.
  • 02
    Anthropic and OpenAI APIs, retrieval, evals, function calling.
  • 03
    Brings an AI-native workflow into your team. Your devs level up too.
  • 04
    Part-time or full focus. Weekly availability agreed up front.
