Over a two-month period, this developer contributed to GetStream’s stream-chat-js and stream-node repositories by delivering three new features focused on scalable backend functionality. They implemented a global app-level file upload and delete API in stream-chat-js, decoupling file operations from channel logic to enable cross-channel workflows and improve code reuse. In stream-node, they enhanced the Feeds API by adding feed visibility management and ephemeral chat message updates, and refactored the FeedResponse model to expose ownership and membership context directly. Their work emphasized modular API design, robust request validation, and maintainable TypeScript code across both API development and integration tasks.
