About

I enjoy turning complex technical problems into dependable, useful products. My current work spans backend and distributed systems, applied AI, native apps, and product-focused full-stack development.

Inkdown	A lightweight Markdown reader and annotator that writes highlights and notes directly into the source file, with offline rendering and native Apple-platform support.	SwiftUI, Tauri, Rust
Reliable Webhook Delivery	A webhook delivery platform with persistent queues, bounded retries, dead-letter handling, receiver-side idempotency, and SLO-driven worker draining.	Python, FastAPI, SQLite
StudySync	A real-time study room backend with cross-instance presence, async aggregation, experimentation, and server-authoritative rewards.	FastAPI, Redis, PostgreSQL, Celery
Code Study	A bilingual English/Chinese reference for common algorithm and data-structure templates. Live site	JavaScript, C++, Python

Outside code

I speak Mandarin, Cantonese, and English, and Duolingo still has things to teach me. Outside code, I enjoy badminton, music, photography, philosophy, and spending time with my two cats.
