Built a multi-tenant visual website feedback platform inspired by Marker.io, enabling visitors to leave screenshot-based comments pinned to exact page coordinates. Developed an embeddable widget, project dashboard, issue management workflow, secure authentication, and subscription billing. Implemented serverless Playwright + Chromium screenshot generation with SSRF protection, HMAC-verified Lemon Squeezy webhooks, Upstash Redis rate limiting, and Row-Level Security using Supabase for secure tenant isolation. Deployed on Vercel with a production-ready architecture.
