Hey, I'm Etan

Full stack developer in Israel. I build products and occasionally let AI build them for me.


What I'm Building

Golems — AI Agent Ecosystem

A Bun workspace monorepo of domain-expert AI agents, each a self-contained Claude Code plugin. Install one into any Claude session — it brings its skills, rules, MCP tools, and context automatically.

5 domain golems + orchestrator + infrastructure:

Golem Domain
RecruiterGolem Outreach campaigns, contact discovery, 7 interview practice modes with Elo tracking
TellerGolem Transaction categorization for tax, payment alerts, expense reports
CoachGolem Calendar management, daily plans, cross-golem status
JobGolem Board scraping (Indeed, SecretTLV, Drushim, Goozali), LLM scoring, auto-outreach
ContentGolem LinkedIn posts, Hebrew tech ghostwriting

Also includes:

  • Ralph — Autonomous coding loop. PRD in, shipped code out. Smart model routing, cost tracking, worktree isolation.
  • Zikaron — Memory layer. 238K+ conversation chunks indexed with sqlite-vec + bge-large-en-v1.5 embeddings. Search your past sessions.
  • 30+ skills, 6 MCP servers, 7 agent profiles, exportable rules library
  • 1,179 tests (4,056 assertions)

Mac runs the brain (Telegram bot, Night Shift, memory). Railway runs the body (email polling, job scraping, briefings).
