Problem
Homeowners face uncertainty and risk
- Most people cannot accurately diagnose HVAC, plumbing, electrical, or appliance issues from a photo or sound alone.
- DIY attempts on the wrong problem can be dangerous (electrical shock, gas leaks, water damage) or costly.
- Calling a professional without context leads to wasted visits, unclear pricing, and poor urgency triage.
- Existing solutions are fragmented: generic search results, video tutorials, or expensive emergency calls — none tailored to the user's specific unit and situation.
Product and business gaps
- No single mobile-first tool combined smart image analysis, audio insights, intelligent guidance, safety checks, and a professional marketplace in one flow.
- Legal content (privacy, terms, FAQs) and business information needed to stay synchronized across app stores, website, and in-app screens — without waiting for a new app release.
- Operations teams need visibility into scans, subscriptions, leads, and assistant quality without involving developers.
- Monetization (subscriptions, scan credits, pay-per-scan, professional tiers) requires secure, server-validated billing and access control.
- Pre-signup users need a way to try the product (guest scans) before creating an account.
Solution
RepairsMe delivers a scan-first, AI-guided repair companion built across four connected layers:
1. Intelligent Scan & Diagnosis
Users select one of 7 home systems, capture media via the in-app camera, and receive:
- Confirmation that the correct system was scanned (water heater, outlet, pipe, etc.)
- Issue detection with confidence scoring
- Severity and safety rules that block unsafe DIY when risk is high
- Localized responses (English + Spanish)
- Clear next steps: guided DIY instructions, cost estimate, safety checklist, find a pro, or AI assistant chat
2. Dual User Roles
- Homeowners — Scan, maintain, subscribe, chat with AI, request professional help
- Professionals — Separate account experience with subscription access, lead management dashboard, and a dedicated AI assistant
3. Unified Content & Configuration
Admin-authored legal documents, FAQs, and business profile are managed in one place and delivered consistently to the marketing website and mobile app, with offline fallbacks for compliance and reliability.
4. Operations & AI Management Console
Business admins manage users, scans, subscriptions, notifications, maintenance mode, app version requirements, and a full assistant management workspace for quality control, knowledge updates, and performance review.
5. Production Cloud Infrastructure
Each major service runs on dedicated cloud infrastructure with secure hosting, automated deployment, and independent scaling — enabling reliable updates without disrupting the live product.

Challenges
1. Multi-Modal AI Pipeline Consistency
Challenge: Seven different home systems, each analyzed differently — some with photo and audio, others image-only — all needed to present the same clear experience in one mobile app.
Solution: Built a unified diagnosis format and a flexible scan registry on the platform. New scan types are added through configuration rather than rebuilding core product logic. The mobile app mirrors the same structure for a consistent user experience.
2. Safety Gating for DIY Guidance
Challenge: Recommending DIY on high-risk electrical or gas issues could cause real harm.
Solution: Implemented safety rules per scan system in the app, plus server-side severity analysis. The product blocks DIY paths and directs users to find a professional when risk thresholds are met.
3. Guest-to-Registered User Continuity
Challenge: Users want to try scanning before creating an account, but scan results must persist after signup.
Solution: Guest trial access with device tracking, anonymous scan previews, and automatic linking of guest results to the new account after registration.
4. Cross-Platform In-App Purchases
Challenge: Apple and Google use different billing formats, validation flows, and subscription lifecycle events (renewals, cancellations, grace periods).
Solution: Server-side purchase verification for both stores, renewal handling, access sync that gates scan credits and chat independently of login, and restore-purchase flows on both platforms.
5. Bilingual Product (EN/ES)
Challenge: Diagnosis copy, DIY guides, safety messages, and legal content all needed Spanish support without doubling maintenance burden.
Solution: Bilingual content layer on the platform plus localized mobile app copy. The operations console supports English and Spanish for FAQs and legal documents from a single source.
6. Design-to-Production Fidelity
Challenge: Translating professional designs (custom splash animations, navigation, card layouts) into a polished mobile experience across iOS and Android screen sizes.
Solution: Responsive scaling, custom components matching design specifications, and a consistent design-token system for typography, color, and layout.
7. Operations Console as a Secure Web App
Challenge: The internal dashboard needed to run as a fast, secure web application with reliable sign-in, session refresh, and live data — without a heavy server footprint at runtime.
Solution: Optimized static build with secure API communication, automatic session refresh on expiry, and an automated publish pipeline to cloud hosting.
8. AI Chatbot Production Operations
Challenge: A consumer-facing assistant needs quality control, cost management, knowledge updates, and regression testing — not just a one-time setup.
Solution: Built a full Chat Studio in the operations console: knowledge management, prompt testing and promotion, quality evaluation sets, scheduled improvement jobs, training data export, budget controls, and user feedback (thumbs up/down).
9. Runtime App Control Without App Store Releases
Challenge: Need to require updates, enable maintenance mode, or switch to read-only during incidents without waiting for app store review.
Solution: Live app settings polled on startup and periodically. The operations console configures normal, maintenance, or read-only mode, minimum app versions, and store links. The app shows appropriate gate screens when required.
10. Multi-Service Cloud Deployment
Challenge: Four separate products, multiple cloud servers, different hosting strategies, and the need for verified releases after every update.
Solution: Standardized release scripts per product: version control → cloud deploy → build → restart services → automated health check. Secure environment configuration on servers and scheduled background jobs for assistant and notification tasks.
11. Legal Content Sync Across Three Surfaces
Challenge: Privacy policy, terms, and FAQs must match across app store listings, marketing site, and in-app screens.
Solution: Single source of truth in the central content store, delivered live to the marketing website and mobile app, with backup files when the network is unavailable (app store compliance requirement).
12. Real-Time Streaming on Mobile
Challenge: DIY repair guides and AI chat responses are delivered in real time; the mobile app must display streaming content reliably.
Solution: Platform endpoints stream DIY guides and chat responses; the mobile app handles live updates for step-by-step instructions and conversational replies.
