| Summary | JeonsterLab is a motion-data labeling system developed to support the creation of a Core ML model for an Apple-platform application. The system collects wrist-motion data from Apple Watch, transfers and reviews the data on iPhone, and allows detailed editing and labeling through a macOS application. |
| Role | iOS and macOS development · Motion-data collection pipeline design · Data labeling workflow implementation |
| Tech Stack |  |
Key Contributions
- Built a Core Motion data collection flow on Apple Watch.
- Implemented Apple Watch-to-iPhone data transfer.
- Designed a workflow for transferring collected data from iPhone to Mac.
- Developed macOS functionality for creating, editing, and labeling motion segments.
- Implemented CSV export for machine-learning datasets.
- Helped construct the dataset used to train the main Jeonster application's ML model.

| Summary | CultureKeeper is a culture-sharing platform that reinterprets vacant and aging spaces in Suseong-gu, Daegu, as shared cultural hubs for young creators and local residents. |
| Role | Service planning · Business model design · User-flow design · Web prototype development and deployment |
| Result | HYPECRAFT BEST INNOVATION AWARD · Best Innovation Award at the WCIF HYPECRAFT Culture Hackathon, Track B |
| Tech Stack |  |
Key Contributions
- Defined the problems faced by vacant-space owners, young creators, and local residents.
- Designed a reciprocal model in which creators use spaces at low cost while providing cultural programs for the community.
- Planned a circulation structure connecting vacant spaces, creative activities, local cultural experiences, and space-maintenance revenue.
- Designed operational assumptions including program demand, revenue, break-even point, and a six-month pilot.
- Implemented a web prototype with Kakao Maps JavaScript API.
- Deployed an accessible web prototype using GitHub and Vercel.
