Backend Developer Needed — Supabase, Stripe, Twilio & Google API Integrations

I have built the frontend of a SaaS web application called Starly — a reputation management platform that helps businesses monitor their online reviews, respond using AI, and automatically send review requests to their customers. The app has been built using Lovable (React) with Supabase as the backend database and authentication layer. The frontend is complete and functional. I now need an experienced developer to build and connect the backend integrations that will make the product fully live. ## What I Need **1. Google Business Profile API** - Pull reviews from Google Business Profile into the Starly dashboard - Allow replies to be posted back to Google directly from the dashboard - Automatic sync every 30 minutes **2. Stripe — Subscription Billing** - Three subscription plans: £29/month (Starter), £59/month (Growth), £99/month (Pro) - 14-day free trial logic on the Starter plan - Upgrade and downgrade between plans - Trial expiry handling — account pauses when trial ends - Webhook handling for payment events **3. Twilio — Automated SMS** - Send automated review request SMS to customers after a visit - Support for international phone numbers with country codes - Opt-out handling — STOP reply automatically updates client status in Supabase - Triggered from the dashboard requests page --- ## Tech Stack - Frontend: React (built in Lovable) - Backend/Database: Supabase - Payments: Stripe - SMS: Twilio - Review Platform: Google Business Profile API --- ## What I'm Looking For - Proven experience with Supabase and React integrations - Experience with Stripe subscription billing and webhooks - Experience with Twilio SMS - Experience with Google Business Profile API or similar review platform APIs - Clean, well-documented code with handover notes - Fixed price quotes only — no hourly billing - Clear timeline provided upfront --- ## Nice to Have (Phase 2 — not required immediately) - Trustpilot API integration - Facebook Reviews API - SendGrid email integration for automated review requests and campaigns --- ## How to Apply Please include in your proposal: 1. Confirmation you have worked with Supabase before 2. An example of a similar API integration project you have completed 3. Your fixed price quote for the three integrations listed above 4. Your estimated timeline to completion I am looking to move quickly. Developers who can start within 1-2 weeks preferred.
