Selected systems

Six systems, built solo on the Anthropic API.

SaaS platformFirst clientPrivate

Hydra

One of Integrate.AI's product offerings: a multi-tenant SaaS platform for governed AI agents. Tenancy enforced at the database with Postgres row-level security, Stripe billing reconciled inside tenant-scoped transactions, every agent action written to an audit spine.

Memory infrastructureStealthPrivate

Pensieve

A firm-owned memory layer, currently in stealth: agents that wake up already knowing the people, the projects and the decisions. Always-loaded core context plus an unbounded archive recalled through hybrid vector search, with a reflection loop that distils sessions into durable facts overnight. It also grades its own health every day.

nightly reflection cost cut by about 95%

Mac appShippedPublic download

Parlay

A native macOS dictation app I built to replace a paid subscription. Speech to text runs locally on the Neural Engine, then Claude Haiku tidies the transcript before it pastes. If the cleanup ever fails, the raw words still paste, so dictation never breaks.

Skills libraryPublic repo

Tokenomics

Eight self-contained skills that cut what an agent pays to read PDFs, spreadsheets, video, logs and web pages. They plug into any Anthropic API harness, and every savings claim is produced by a meter against a fixture corpus and committed as evidence.

Fine-tuningPublic repo

Post-training

For workloads where a frontier API is the wrong answer: LoRA fine-tuning Qwen3-4B on a 16GB MacBook Air with Apple MLX, mapping macro snapshots to tactical asset-allocation tilts entirely on device. Ships with a research brief on methods, costs, and the break-even against frontier APIs.

Graph engineeringPublic repo

Macro briefing system

A worked sample of graph engineering: an autonomous daily macro briefing in an asset manager's house style, orchestrated with the Claude Agent SDK in Python. A manager sets the day's focus, three specialist sub-agents research in parallel with live market-data tools, and a verifier scores every memo against a nine-point style checklist. Failures get one retry with feedback.

In the field

Live systems, paying clients.

Deployed for clients of Integrate.AI and anonymised here. Named references on request.

FinTech, in build

Sales follow-up agent

After a sales call, it picks the right contract and order forms, fills them in, files them and drafts the follow-up email with everything attached. The rep reviews and sends. It never sends on its own.

Hospitality, London

Campaign orchestrator

A marketing engine for a multi-site wine bar group: plans, drafts and schedules campaigns across channels from one brief.

Events, premium venues

Function-sheet builder

Turns enquiry-to-event admin into structured function sheets the operations team runs the venue from.

Private client

Morning brief dashboard

A daily personal intelligence brief covering markets, mail and diary, rendered before the client wakes.

Approach

Product offering, private build

Hydra

One of Integrate.AI's product offerings. A multi-tenant SaaS platform where each client firm gets governed AI agents behind its own hard tenancy wall. The code is private; the architecture is the story.

Pensieve

Agents forget everything between sessions; firms cannot afford to. Pensieve is a firm-owned memory layer: every Claude surface a company uses wakes up already knowing the people, the projects and the decisions, and what it learns today is recalled tomorrow. It runs in production daily as the memory spine of my own agent fleet, and an enterprise blueprint takes the same codebase into a regulated client's own cloud tenant.
