§ Built with Friday
The home page is the three core projects. This page is what they add up to: things I built with the same memory, sessions, and dogfood loop. Some read from Friday-ai directly. Others were just built with the Claude Code and Sandcastle workflow.

Automated-trading research system
A private automated-trading system I am building on the same Unraid server, and one of Friday-ai's real consumers. Every decision it makes records what it assumed and how it turned out, and the next session reads those post-mortems before it proposes anything. A research build, not a signals service, and it is not public.
App for a 4x4 off-road club
A Flutter mobile app and a marketing site for a 4x4 off-road club: trip planning and sign-ups, member profiles and vehicles, marshal tools, and a trip logbook. Built with the same Claude Code and Sandcastle loop the home page describes.
Photo archive for the off-road club
The club's photo archive, live at media.ad4x4.com. Members upload after a trip, and it files the photos into that trip's album, cuts thumbnails, reads the camera and date and GPS off each file, and works out where the shot was taken. It holds no passwords of its own: the club's backend stays the source of truth for who you are.
Voice and vision AI for smart glasses
A real-time AI companion for Meta Ray-Ban smart glasses and iPhone. It sees what the camera sees, hears you, and answers out loud, with live scene description and a chat interface. Built with the Friday workflow.
Personal trading command center
A single-operator command center I am building to keep market data, a dashboard, and my own alerts in one place. Every action is gated behind my manual approval; nothing trades on its own. A private tool, not a signals service, not advice, and not public.
Community + media platform for AMG enthusiasts
An independent UAE community and media platform for performance-Mercedes enthusiasts: a club, stories, events, and a gallery in one place. Built with the Friday workflow. Unofficial, not affiliated with Mercedes-AMG.
Multi-agent decision skill for Claude
A Claude skill that convenes a board of specialist agents (an architect, a security engineer, a UX lead, a devil's advocate, and more) to debate a hard development decision, critique each other, and hand back one synthesized recommendation. It is the skill that produced this site's plan.
Evidence-first market-analysis skills
Two analysis skills that run inside ChatGPT and Codex rather than Claude, which is half the point: the workflow travels. Their discipline is provenance. Source data, calculation, and my own inference stay in three separate buckets, and when the evidence is not current enough the skill says so and stops rather than guessing. Research tooling, not a signals service, not advice, and not public.
§ Collaborations
Projects I am collaborating on with other people, built on or alongside the same workflow.
Backend for the Ad4x4 club app
The Django REST backend behind the Ad4x4 club app. Built by another developer; I collaborate on it with the same Claude Code and Sandcastle workflow.
