Seventeen years on the customer's side of enterprise software — Premier support at Microsoft, post-sales engineering at Secure Islands, Tier 3 escalations at Claroty, IT management at Profero. Now I build the systems that do that work faster.

alfred — Always-on Claude Code sessions driven from a Telegram bot. Live streaming output, permission prompts as inline buttons, multi-agent management, a scheduler, voice notes.
kappa — A judge you haven't measured is just a vibe. Cohen's κ, drift detection and a prompt bias linter for LLM-as-a-Judge, in one stdlib-only file. No install, no API keys.

TLV-quest · live — Self-running urban quest platform for the Tel Aviv Port. Organizers configure a game and then watch it; atomic Postgres transitions, pg_cron workers, and a schema-drift gate that fails CI.
whatsai · live — Persona chat where characters also talk to each other. Opt-in long-term memory per persona, rolling summaries, live voice, push reminders, and a per-model cost dashboard.
