Summary
👤
Senior🎓
Top SchoolMariusz Mielnik is a founder and AI architect with 25 years in IT and a decade-plus focused on e-commerce architecture, product integrations, and team leadership. He built and scaled one of Poland’s top premium toy retailers into a 9M+ PLN business by automating supply chains, inventory strategies and real-time supplier APIs, and now channels that operational experience into Flowmerce.ai’s conversational commerce vision. As CTO/owner at ECBOX he delivered large-scale B2B integrations and paperless document workflows across international partners, eliminating manual processes for high-volume operations. Comfortable shifting between hands-on engineering and strategic architecture, he repeatedly delivers sub-second performance, zero-downtime deployments and enterprise-grade reliability during peak load. Notable for turning messy operational constraints into automated systems, he combines deep e-commerce domain knowledge with applied AI to make product search and discovery feel like natural conversation. Based in Warsaw, he pairs pragmatic engineering with a founder’s drive to commercialize novel AI approaches.
