I'm Justin, also Ziheng Zhong (钟子恒), a graduate student in Management and Analytics at New York University (Sep 2025 – May 2027). Before NYU I completed a Bachelor of Science at the University of Toronto, St. George, double majoring in Statistics and Mathematics.
My recent work focuses on AI, backend, iOS and data systems. During my backend internship on Xiaomi's Proretail team I built clue-statistics modules, expanded filtering interfaces, and optimized SQL logic to cut clue-count response time by about 100 ms.
These days I'm building ohmycoin, a local-first iOS spending tracker; ohmybody, a HealthKit dashboard; ohmytask, a Kanban task manager for iOS and macOS; and JobMuse, an AI-assisted career-ops workspace in React / Express. Outside of code I shoot photos.
