What we've shipped, and where the judgment comes from.

Two different kinds of evidence. Below is work A&O built and operates — you can go and use it. Further down is the founder's prior experience, which is where the operating judgment was formed. We keep them separate on purpose.

Built by A&O

Shipped as A&O. Every item links to something live.

Cairn

A privacy-first iOS journalling app, live on the App Store.

Runs entirely on Apple’s on-device models — no cloud, no data leaving the phone. Per-entry extraction, deterministic aggregation, nightly memory consolidation, and on-device embeddings. Product, pricing, and go-to-market owned end to end.

Alfred

A production multi-agent orchestration platform.

Custom LLM routing across multiple model providers, with autonomous agents handling QA gating, memory consolidation, and policy enforcement. Runs on self-managed infrastructure and builds the work you see here.

This website

Built and maintained by that same system.

The site you are reading was assembled by the delivery factory rather than hand-built — tiered model routing, structured action validation, and an audit trail, in continuous production since early 2026.

Where the judgment comes from

Engagements the founder led in roles at prior organisations — not delivered as A&O. Anonymised to protect commercial confidentiality.

If you want the same delivery system pointed at one of your workflows, that's Ship One Thing.
