Konrad Kowalik
Product Engineer
I’m an AI-native Product Engineer and Full-Stack Developer with 4.5+ years of experience taking products from discovery and UX through frontend, backend, and AI integration. I’ve built and shipped AI-powered products used by more than 100,000 people, with hands-on work across LLM integrations, agentic workflows, automated data pipelines, and high-load systems. I work best in small teams where I can turn user signals into product decisions and own the result through production.
Based near Katowice, Poland. Open to hybrid work in the region and fully remote roles anywhere.
