What I'm looking for

I'm looking to build production-grade, AI-integrated products where I can improve performance, automate workflows, and deliver real-time collaborative experiences.

At Reventlabs, I build Closot, a scalable Notion-style productivity platform with real-time collaboration, Kanban, timeline and chart views, and a template marketplace.

I engineered a Claude-powered AI assistant using MCP to autonomously handle workspace tasks, reducing manual effort by about 40%. I also built 20+ third-party integrations and REST API connections, reducing data-fetch latency by about 25%.

I improved Closot’s rendering architecture from roughly 80 to 10 component re-renders per interaction and built a block-based TypeScript and React editor supporting 1,000+ structured documents. I’ve also implemented offline-first syncing with IndexedDB and local storage, plus Pinecone semantic search that improved relevance by about 35%.

Beyond product engineering, I maintain Playwright end-to-end tests for the MTM admin panel and built Talk-a-Tive, a real-time chat application using React, Node.js, Express.js, MongoDB, and Socket.IO.
