What I'm looking for

I'm looking to improve AI systems through research, evaluation, prompt design, and high-quality multilingual data, especially on complex STEM and research-intensive content. I value work where accuracy, clear reasoning, consistency, and user experience directly improve model performance.

I've evaluated AI-generated claims and STEM content for Invisible Technologies and Scale AI, reviewing factual accuracy, reasoning, source reliability, and instruction-following in Polish and English. I create prompts, rubrics, JSON-based evaluation tasks, and clear evidence-based justifications that help improve safer, more consistent user-facing AI responses.

My background also spans global SEO, social media, and e-commerce for Smart Air, Dr Mercola, eToro, and Surfshark. I grew Smart Air’s monthly Twitter/X impressions by 734% without paid ads and delivered marketing, localization, and content services for 165+ international Upwork clients.
