Eli Benhaim

Senior Full Stack Developer · AI Products on the Cloudflare Edge

I've built web products for nine years, from the architecture down to the tests and the docs. For the last three, that has meant AI products on Cloudflare Workers: multi-agent systems, real-time backends over WebSockets, tool calling and RAG.

Ask it about MyndReader. It plays songs in the chat and opens the discography, with Apple Music, Spotify and YouTube links. It also sells merch and tickets, shows the band's videos and photos, and introduces each member.
