What I'm looking for

I'm seeking a long-term remote freelance AI training or data annotation engagement where I can apply native Hebrew judgment, English evaluation, guideline-based QA, and reliable independent work.

I've run independent, accuracy-critical operations for over 20 years, including an 11-year ATM route in the Casponet network and a Strauss dairy distribution business built from zero. Since 2022, I've supervised bookkeeping for multiple construction-supervision firms, checking records against standards, finding discrepancies, and enforcing corrections.

I use ChatGPT, Claude, and Gemini daily to design prompts, evaluate correctness, style, and quality, and build working websites with AI coding assistants. As a native Hebrew speaker with excellent English, I bring dependable guideline-based review, cultural and linguistic judgment, and long-term remote freelance availability to AI training work.
