Problem: Apps need a secure, organized backend to handle users, orders, products and AI features.
Solution: Built a centralized API Gateway (BFF) in n8n Cloud. One webhook handles validation, API key security and rate limiting, then routes to sub-workflows: Users (register/login), Orders (stock check, totals, status), Products (search), and AI (OpenAI chat, recommendations, review summaries). Supabase is the database.
Tools: n8n, Supabase, OpenAI API, Webhooks
Self-initiated demo project.
I'd test authorization separately for each sub-workflow, especially Orders. Does the gateway pass a verified user identity through, or does the Orders workflow check that the caller can access each order?

Nice to see a single webhook taking care of validation and rate limits before handing off to the user and order flows.
🐾 What if a one-person business could run like a team of five?
I built Suds & Scruffs — a mobile dog grooming site for a solo groomer in Portland, OR. It's not just a booking page; it's a full operations brain:
✨ Customer side — premium booking flow with real availability, zone-based route days, and a spa-day confirmation pass 📋 Owner side — dashboard, calendar, customer directory, and an AI Inquiry Inbox that reads messages, extracts details, and drafts replies in Maya's voice ⏱️ Automations — confirmations, nudges, at-risk handling and waitlist slot offers that run themselves — every message logged, every email branded
The result: less time chasing replies, more time with the dogs. 🐕
Built entirely with Lovable.
