Résumé

Timurtek Bizel

Design Engineer & AI Product Builder

Design engineer and AI product builder. For more than a decade I have worked inside Apple, Disney and startup product teams, turning complex ideas into systems people can use, ship and maintain: product direction, interaction design, production frontend, design systems, retrieval-backed AI and the automation underneath a team. I also build and operate independent products end to end.
