Developed an end-to-end property management platform that streamlines rent collection, tenant onboarding, and daily operations. The project consists of a React Native mobile app for tenants, a React.js administrative web dashboard, and a secure Node.js/MongoDB backend. Key Achievements: • Integrated Razorpay for cross-platform rent payments and fee tracking. • Automated tenant onboarding by generating PDF rental agreements with digital e-signatures (react-signature-canvas). • Built a real-time notification engine utilizing Firebase (push notifications) and automated WhatsApp alerts. • Designed complex role-based access control to securely handle data for Admins, Tenants, and Local Authorities. • Optimized API response times and background task processing using Redis and Node-cron. Tech Stack: MERN Stack (MongoDB, Express, React, Node.js), React Native, Redis, Razorpay, WebSockets.
