Hi — I'm Justin / Ziheng. Master's student in Management & Analytics at NYU, with an Arts & Science bachelor's degree in Statistics & Mathematics from U of T. I write Java and Python for backend systems, Swift for iOS, R and SQL for data, and AI-assisted tools that hold the rest together.

About

~/about.md

I'm a graduate student pursuing a Master of Science in Management and Analytics at New York University (Sep 2025 — May 2027). Before NYU, I completed a Bachelor of Arts and Science at the University of Toronto St. George campus, double majoring in Statistics and Mathematics (Sep 2021 — Jul 2025).

My recent work focuses on AI, backend, iOS, and data systems. During my backend developer internship at Xiaomi Proretail (Jul 2024 — Aug 2024), I built clue-statistics modules, expanded filtering interfaces, and optimized SQL logic to reduce clue-count response time by about 100 ms.

Recent projects include Coin, a local-first iOS spending tracker with budgets, widgets, and on-device intelligence; Body, a HealthKit dashboard for Apple Health trends and widgets; and JobMuse, an AI-assisted career-ops workspace built with React / Express. In JobMuse, the backend owns provider keys, runs career-ops scans and report jobs against local application data, streams server-sent logs back to the GUI, and connects those AI-assisted results to pipeline editing, application tracking, and script runners.
