Built a real-time collaboration platform using WebSockets for instant syncing across users. Designed the frontend with React and the backend with Node.js, handling thousands of concurrent connections with graceful degradation.
Engineered a data pipeline processing millions of events per second. Built custom serialization for throughput optimization and implemented backpressure mechanisms to handle traffic spikes without data loss.
Created a CLI tool that automates repetitive developer tasks — scaffolding, linting setup, deployment configs. Designed a plugin architecture so the community can extend it. Used by thousands of developers.
