02 — What I do

What I do

A ribbon of ember light folded into an endless loop
01

Automate

The repetitive work eating your week, handed to AI. Inbox, documents, follow-ups, reports.

Glass blocks lit from inside, stacked into a tower
02

Build

AI your customers actually use. Assistants, WhatsApp bots, smart search, instant content.

A glass prism turning tangled threads into one clean beam
03

Clarify

What's real, what's hype, and where AI pays you back first.

An ember flame passed from one glass sphere to the next, lighting each one up
04

Teach

Make your team AI-native. I set up Claude Code and AI tools, plug AI into your workflows, or teach your team to do it themselves.

Matchi

Co-founder & CTO · 2026 – now · Tel Aviv

Every real-estate broker's WhatsApp becomes an AI studio. Listings, ads, brochures, videos and buyer matching. No app to learn.

As CTO I build the product brokers use, and the systems the company runs on.
