Justin has deep hands-on experience across the stack from animated UIs and custom CMSs to APIs, web scrapers that drive most revenue, and an on-device computer vision model that recognizes 20,000 Pokémon cards in real time. His background in business operations and ecommerce informs pragmatic product decisions and growth strategies, proven by an acquisition of his Popspedia app by Funko and its conversion into their official app. Based in Irvine, CA, he pairs entrepreneurial grit with attention to detail and a playful side—building “silly games and stuff” while shipping production-grade systems.
