Dan Ephrat

I build software, end to end.

Optimizers, agents, email tooling, and the plumbing that makes them reliable. Everything below is something you can try, watch, or read the code for.

Try it live

Runs entirely in your browser. Nothing to install, no sign-up.

Production Line Builder

A visual editor for factory-line layouts: place stations and material piles, wire up routes, and an integer-programming solver (HiGHS, compiled to WebAssembly) finds batch sizes and raw inputs — minimizing waste first, then resources, then time. All client-side; your layouts save to your browser.

Watch it work

Recorded against seeded demo data — no real mail involved.

Terminal recording of Claude answering a question about an email archive through the catalog MCP server

catalog-mcp

An MCP server that gives AI agents semantic recall over an email archive. Every thread is LLM-tagged on sync; agents search by what you actually remember (“the invoice from the roofing guy, sometime last spring”), not exact keywords.

Scribe review dashboard: an incoming email question, the AI-drafted reply grounded in the business's website, and approve/edit/dismiss actions

Scribe

Drafts replies to incoming business email, grounded in the business’s own website content. It answers what the site actually covers and says so when it doesn’t know, instead of inventing. A human reviews every send.

Code to read, with the design notes in each README.

Fastest way is email.
