Grzegorz Naliński

I'm transitioning into AI Training, AI Evaluation, and AI Quality work after 20+ years of business data analysis, supplier evaluation, negotiations, and process management. Since September 2025, I've used ChatGPT, Claude, and Gemini hands-on for research, document analysis, fact-checking, prompt iteration, and comparing model outputs.

At Selgros/Transgourmet, I managed Sport, Camping, and Garden categories across 16 stores, accountable for approximately PLN 40 million in annual network sales. I managed sales, margin, budgets, inventory, supplier negotiations, and direct imports with more than 30 factories in China and Vietnam; I met or exceeded planned financial results 10 times.

I've also run my own transport business end to end, including contracts, recruitment, costs, documentation, and work organization. I bring a practical, evidence-focused approach to finding inaccuracies, inconsistencies, unsupported claims, and hallucinations in complex information.
