👋 Hi, I'm Fuzail Haaris
Software Engineer focused on building privacy-first tools, improving developer workflows, and delivering clean, reliable user experiences. I enjoy working across the stack — from browser extensions to full-stack applications — with a keen interest in AI, automation, and real-world usability.
🚀 Featured Project — PasteGuard
PasteGuard is a privacy-focused browser extension designed to prevent accidental leakage of sensitive information when interacting with AI models, chatbots, or external platforms.
🔐 What it does
Sanitizes private data on paste using configurable rules
Supports literal and regex-based transformations
Two-way mode restores real values when copying back
Smart login-field detection
Site whitelisting for trusted domains
All logic runs locally with no tracking
Built with Manifest V3, TypeScript, and a custom rule engine
