> /about
I'm an undergraduate studying Computer Science and Mathematics at UBC, with hands-on experience across data analysis, full-stack development, and iOS engineering.
I like building things end-to-end — from a SwiftUI app with real-time system integrations to a TypeScript prototype backed by real UX research. I care about writing code that's correct, clear, and doesn't need a rewrite in six months.
Languages
- TypeScript / JavaScript
- Swift
- Java, C++, Python
Tools & Frameworks
- Next.js, React, Tailwind
- SwiftUI, ActivityKit
- Figma, Git

Live, embedded demos — no download or screenshots needed. Try them right here.
A premium iOS utility for professionals with flexible schedules. Dynamically calculates your exact clock-out time in real-time, factoring in break deductions, calendar-synced OOO events, and Dynamic Island / Live Activities.
- Recomputes clock-out time every second from stored timestamps — survives a force-quit with zero drift
- Dynamic Island + Live Activities surface live status on the lock screen without unlocking
- EventKit-aware: auto-shrinks target hours around calendar OOO / time-off events
A functional TypeScript-based high-fidelity prototype supporting deck creation, spaced-repetition scheduling, and collaborative studying — validated with real UX research before a line of production code was written.
- Deck creation and spaced-repetition scheduling built from scratch in TypeScript
- Collaborative decks so study groups can share and review together
- De-risked with low-fidelity prototypes and Wizard-of-Oz testing before the full build
