Case studies
Each one is a real build with a recorded run, a short video and the full write-up you can read without watching.
Tether: One Desk, Two Macs
A 2015 MacBook Pro with a swollen battery brought back as a second worker. My browser remote Tether (~150 ms → ~14 ms per frame), Synergy for one keyboard and mouse, SSH both ways, and Chrome automations driven from the Air over a checked tunnel. Personal setup.
Claude Agent Loop Guard
A Claude tool-use agent that browses a shop with Playwright, with the guards that stop it looping or overspending: max turns, a USD budget checked before every call, a repeat-call breaker, checkpoint/resume and a cost log. 6/6 tests. Demo project; runs against a scripted fake model.
SaaS Billing Starter
Multi-tenant orgs with owner/admin/member roles enforced by Postgres row-level security, a billing gate in the database, and a signed, idempotent, order-safe Stripe webhook. 12/12 offline tests. Demo project with fictional data, Stripe test mode.
LLM Eval Harness
A 20-case golden dataset, exact-match and LLM-as-judge graders and a GitHub Actions gate that fails the PR when quality drops or an urgent ticket is missed: good run 19/20 passes, regressed 14/20 fails. Demo project with synthetic recordings.
WordPress Care-Plan Report, every Monday
A weekly plain-English email for a clinic owner: is the site online, updates waiting, backups, errors, speed, and a short to-do list. n8n checks the site, Claude writes it, code checks every number against the real data. A plugin put behind on purpose was named on the next run. Demo for a fictional dental clinic.
WordPress Site Rescue, down → back
A clinic site broken three ways (white screen after a plugin update, stuck in maintenance mode, a staged hack) and brought back each time: cause found from evidence, fixed, booking form checked. Fixed in 7.0 s, 17.5 s and 23.6 s. Demo for a fictional dental clinic.
WordPress Speed Fix, before → after
A slow clinic site made fast with one script and free plugins: the main picture shows in 4.9 s instead of 104 s on a slow phone, page 26.0 MB → 1.1 MB, same design. Demo for a fictional dental clinic.
AI Inbox Triage + Invoice Extractor
Sorts every email, pulls supplier invoices into one list (₱28,150 due, overdue in red) and drafts patient replies. 8 emails in 47 seconds. Demo for a fictional dental clinic.
Clinic Chat Assistant
Answers from the clinic's info sheet, books a real open slot, and hands questions it can't answer to staff. Demo for a fictional dental clinic.
AI Lead Responder
A website enquiry gets a personal reply in 8.3 seconds and every lead is saved to a lead sheet. Demo for a fictional dental clinic.
Tasks: Laravel API + Next.js
A tested CRUD app built test-first with Claude Code in a 4-hour assessment, with a 7-minute code walkthrough.
