E-commerce Backend with Admin Dashboard & API Integration

I need an experienced web developer to build a scalable backend for an e-commerce platform. The system should include user authentication, product management, shopping cart, order processing, and payment gateway integration. The project also requires development of a RESTful API for frontend and mobile app integration, as well as an admin dashboard for managing products, orders, and users. The solution should be secure, well-structured, and optimized for performance and future scalability.

Push notifications for an AI productivity PWA

I have a live Progressive Web App (herelet.me) built with React/TypeScript, Supabase, and Lovable. It's a productivity tool for ADHD users and I need push notifications so I can re-engage users when they have tasks waiting. The stack: React frontend (built via Lovable, code on GitHub), Supabase for backend/auth/edge functions. What I need: 1. Service worker setup that handles push notifications reliably without breaking existing PWA caching (I've had issues with service workers causing blank screens, so this needs to be done carefully) 2. Web Push API integration with VAPID keys stored in Supabase 3. Permission request flow that feels friendly, not aggressive — prompt after the user has completed their first brain dump, not on first visit 4. Ability to trigger notifications from Supabase edge functions (e.g. "You have 3 tasks waiting" or "Your quest is paused — ready to pick it up?") 5. Rich notifications with app icon and tap-to-open deep linking back to the relevant screen 6. Cross-browser compatibility (Chrome, Safari, Firefox) 7. Unsubscribe option in the app's Profile tab Important context: the previous service worker implementation caused caching issues that broke the app on Chrome. I need someone who knows PWA service workers well enough to avoid that happening again. Thanks in advance!
