Top SchoolMark Jarecki is a technical product leader and founder with 10+ years of experience building large-scale mobile and web products across Europe and beyond. He has led engineering organizations of 35 engineers across four countries at Vinted, driving architecture, performance, observability and a DDD-based modularization that halved code coupling for 20+ teams. Previously he shipped internationalization frameworks at Revolut, improved delivery velocity and CI practices, and used data-driven UX and programmatic design to boost retention in research settings.
