Local-first Japanese dictionary app built with SwiftUI, MVVM, and a Clean Architecture–inspired layered design. Currently in local development.
- Built a local-first dictionary app with a 293K-entry, 52 MB SQLite database generated by a Python pipeline, bundled as an app resource and queried through GRDB
DatabaseQueue. - Optimized prefix search with
PRAGMA case_sensitive_like=ON, improving benchmarked queries from ~16 ms table scans to ~0.03 ms multi-index lookups. - Designed a four-layer architecture (
AppDependencies → Scene → Store → View) following MVVM and Clean Architecture principles; applied the Repository pattern with protocol-based abstractions and dependency injection to decouple Domain logic from UI and storage frameworks. - Combined GRDB-managed SQLite for read-heavy reference data with SwiftData for user state; wrote 13 unit tests with Swift Testing covering domain use cases and repository behavior.
- Roadmap: SQLite FTS5 full-text search, actor-isolated repositories under Swift Concurrency, TestFlight beta.

Simulation-first benchmark for human-robot collaboration in scientific laboratory environments.
- Extending the LabUtopia simulator into a benchmark for natural-language human-robot collaboration in scientific laboratories, focusing on clarification, safety-aware refusal, grounding, and structured action logging.
- Designing an evaluation framework to compare planner architectures (LLM, VLA, and hybrid systems) on multi-step laboratory protocols; sim-first phase planned for 6+ months before hardware integration.
- Coordinating with 3 procured robotic platforms for future hardware integration; prioritizing rigorous evaluation methodology over demonstration-driven research.
Experience
GlucoPI
B.E. Graduation Project · Advisor: Qi Zhang, PhD, Professor
Feb. 2025 – Jun. 2025 · Shanghai
WeChat Mini Program for diabetes management, doctor-patient communication, and glucose prediction.
- Built an end-to-end diabetes self-tracking app with WeChat Mini Program frontend, FastAPI backend, MySQL / MongoDB storage, and WebSocket doctor-patient chat.
- Implemented login and permissions, glucose / diet / insulin records, doctor-patient pairing, real-time messaging, and trend charts.
- Added short-horizon glucose prediction in PyTorch by reproducing the GluPred pipeline and running experiments on OhioT1DM.
- Integrated a lightweight LLM Q&A feature for non-diagnostic health guidance.

Dec. 2023 – Dec. 2024 · Shanghai
Machine-vision teaching platform for classroom attendance and course management.
- Implemented real-time face-recognition attendance with RetinaFace detection and ArcFace embedding-based identity matching.
- Built teacher / student mobile workflows for class setup, attendance records, and basic engagement statistics.
- Developed a Flutter client and FastAPI service with a clear frontend-backend split.
Interests
- Product-First Engineering — Building products that solve real problems; treating iOS, backend, and full-stack as means rather than ends.
- iOS Native Architecture — Local-first design with clean Domain / UI separation; currently focused on shipping native iOS apps as the most direct path to product impact.
- Research-to-Product — Bridging VLA / LLM research from graduate work to consumer mobile experiences.
