I connect the tools a business already runs on — CRMs, automations and AI agents — and build them to keep working when something upstream fails.

Day to day that is n8n and Zapier pipelines against HubSpot, Salesforce and Pipedrive. On my own time it is shipped products, built to degrade gracefully instead of failing loudly.

An AI agent that improves its own harness (instructions, skills, memory, guardrails) safely. Every change is tested in a sandbox against a task bank, with a blind holdout against reward hacking, and reaches the real harness only after a human approves it. In development; private repo, demo on request.

self-improving agents · sandboxing · human in the loop · zero dependencies

A desktop pet that shows what Claude Code is doing, and says what it is waiting for when it stalls on a permission prompt. No network and no transcript reading: it watches the JSON files that Claude Code's hooks write. Download →

Migrates playlists between Spotify and YouTube Music without adding the wrong song: it scores every candidate, vetoes wrong artists and versions, and asks when it cannot tell two apart. Site →

An OWASP Top 10 auditor that sweeps a repository for vulnerable patterns, secrets and dependencies, and reports in SARIF for CI. Incremental mode rescans only the diff.

A coding agent built from scratch on a raw agentic loop: an orchestrator and specialised sub-agents, with nothing hidden behind a framework.

A desktop invoicing app that replaced a legacy Microsoft Access system in a real business, with no ODBC driver or Access install needed at runtime.
