Senior Full-Stack Lead for Live Joinery Ops App (Part-Time, AU hours)

We run JoineryOS, a live web app for a Sydney joinery shop: scheduling, job costing, bills and crew hours. It's built by AI coding agents with a full test suite, a decisions log and a deploy script. We need a senior full-stack lead, 10 to 15 hrs/week, to: - review and approve the AI agents' work - unblock stuck builds - own releases to production Where we're heading (you should have led at least 2 of these): - security hardening and access control - multi-tenant / separate instance per shop - cloud storage integrations (OneDrive, Google Drive, Dropbox) - Xero, MYOB and QuickBooks sync - native iOS and Android apps First 3 months: harden and polish the live core for paying beta shops. Must have: 7+ years full-stack, shipped and maintained a live app, strong code review, AU/NZ timezone overlap. Nice to have: experience working with AI coding agents. Starts with a paid 1-week trial on a real task. In your proposal, tell us about one production bug you caught in code review.
