Summary
👤
Senior🎓
Top SchoolJulian Trajanson is a CTO and AI-driven engineering leader with a decade of experience building production computer vision and machine learning systems for retailers and startups. He led early stealth teams at Jet/Walmart that became Walmart’s Intelligent Retail Lab, delivering ML systems deployed across 2,400 stores and managing models that materially reduced shrink and powered automated checkout. As a founder and CTO he has shipped end-to-end platforms—vector search, embedding pipelines, microservices, and monitoring—using a broad stack from PyTorch and FAISS to Kubernetes, GCP/Azure, and React. Julian blends hands-on model design and deployment with people leadership, having managed annotation programs, engineering squads, and cross-functional product tradeoffs to push model accuracy past 95%. He also brings entrepreneurial grit from multiple co-founder roles, including leading a publicly traded biomedical startup through fundraising and IP coordination, an uncommon mix of deep AI product experience and real-world startup finance. Based in New York, he pairs Wharton-trained analytical rigor with a practical bias for shipping scalable, impact-focused ML systems.
