...word filtering and moderation controls to improve platform safety. For real-time functionality, I integrated , allowing users to receive feedback-related updates without manually refreshing the application. The platform supports media attachments through Multer and Cloudinary, while MongoDB Atlas is used for persistent data storage. To improve performance and scalability, I implemented Redis using Upstash, BullMQ, and ioredis for caching, background processing, asynchronous tasks, and job scheduling. I also developed a Developer API and Embeddable Feedback Widget as a premium feature. This includes API-key-based authentication, secure hashed API keys, request logging, usage tracking, API endpoints for feedbacks/links/polls, and a dashboard for managing integrations and API us...
