Flipshope Extension
Browser Extension
A high-performance Manifest V3 browser extension installed by hundreds of thousands of users. Injects real-time interactive price trend charts, automated coupon scrapers, and cross-store bargain discovery right onto product pages.
Engineering Achievements
- Engineered a resilient three-tier Manifest V3 architecture: background service worker (API/auth/caching), content scripts (server-driven DOM scraping selectors, MutationObserver SPA handling), and React popup.
- Added price-drop push notifications and flight-fare comparison across 35+ tracked production releases.
- Optimized DOM injection for sub-10ms render latency without causing reflows on complex e-commerce pages.
- Integrated DigitalOcean Spaces for direct-to-cloud telemetry and screenshot capture.
