Fileverse is a Web3 file management and collaboration platform that focuses on privacy and on-chain functionality. It offers a suite of tools similar to Google Workspace and Notion but with an emphasis on decentralized storage, end-to-end encryption, and user control over their data. I contributed in implementing a decentralized document collaboration system with real-time editing by leveraging Redis for caching user document lists and content with efficient invalidation strategies. I contributed in building a hybrid commenting system combining WebSocket-based real-time comment broadcasting with on-chain confirmation via a custom indexing service. Also, integrated IPFS for decentralized comment storage and used Pimlico APIs to verify on-chain comment status with a robust retry and failure handling mechanism. Focused on performance, scalability, and data integrity by maintaining minimal storage and implementing detailed logging across verification flows.
