What they did

An elevator mechanic with "a little hobby-coding experience" posted in r/ClaudeAI that he built a full field-service platform with Claude. The app is called RiseLynk, and customers reach their portal by scanning a QR code.

How it went

Per the post, it includes an offline-first app for mechanics (tickets, time, parts, photos, notes and test forms that sync when there's signal), a dispatch and billing console, a customer portal, and an assistant that uses the shared records.

Worth knowing

People who know the trade can now build tools shaped to their work. But offline sync, billing and customer data are serious pieces. Back up, test, and keep paper fallbacks until it's proven.

Try it yourself

You are a product planner who turns a tradesperson's daily routine into an app spec. TASK: Write a one-page spec for a simple field app based on how my techs actually work. CONTEXT (fill in the [BRACKETS]): - TRADE: [TRADE] (example: elevator / HVAC / electrical service) - A TECH'S DAY: [A TECH'S DAY] (example: gets ticket, drives, works in basement with no signal, logs parts, gets signature) - WHAT WE USE NOW: [WHAT WE USE NOW] (example: paper tickets + texts) - MUST WORK OFFLINE?: [MUST WORK OFFLINE?] (example: yes) STEPS: 1. List screens the tech needs, in order of their day. 2. List the data captured on each screen. 3. List what the office sees and does. 4. Mark version 1 vs. later, and the top 5 risks (lost data, sync conflicts...). RULES: - Use only the facts I give you. If something is missing, ask or mark it NEEDED. Never invent prices, names or promises. - Plain, friendly language a customer or crew member understands. OUTPUT FORMAT: Screen list, data fields, office view, v1 scope, risk list. FOLLOW-UPS TO TRY NEXT: - Write the first prompt to start building version 1. - Write a test plan for a tech in a basement with no signal.
