## Core Pillars & Selected Projects

### 1. Fintech & Large-Scale Systems
Advisory and systems engineering for multi-million-user financial institutions.
- **GenAI for Financial Service (`coop-bank-genai`)**: Authored GenAI strategy report and built cloud-to-on-premise pilot RAG systems for Korea's largest cooperative bank.
- **SyndiMatch (`syndimatch`)**: Automated syndicated loan document processing using fine-tuned extraction models.
- **Justin (`justin`)**: Predictive model for micro-installment lending approval.

### 2. Agent Orchestration
Rapidly prototyped autonomous agent coordination systems and developer tools.
- **PeriCare (`pericare`)**: An iOS personal-tracking prototype shaped by literature review, paper system sketches, and an information-architecture redesign. The case study focuses on six design decisions around uncertainty, daily use, personal context, constrained AI, privacy, and inspectable reports; formal usability and clinical validation remain future work.
- **Chat2Meet (`chat2meet`)**: AI agents that negotiate calendar schedules in real-time. (Vercel x Google DeepMind Hackathon)
- **Panoptes (`panoptes`)**: Multi-agent video search and intelligence analysis engine. (NVIDIA Hackathon)
- **AI City Council (`aicitycouncil`)**: Spatial simulation of citizens debating local legislation with AI agents.

### 3. Interface Innovation
Exploring spatial UI, real-time feedback, and physical computing.
- **Cosmos (`cosmos`)**: A spatial conversation browser that evolved from a desktop sphere into a VR reading wall. Four exploratory walkthroughs shaped an orient → focus → read → return loop, inspectable topic/source placement, seated reading, and explicit human-factors questions. (Anthropic Hackathon)
- **InsideMo (`insidemo`)**: wind-shield HUD autonomous driving passenger explanation engine. (Lovable Hackathon)
- **Arduino MCP (`arduinomcp`)**: Custom Model Context Protocol (MCP) server linking LLMs directly to hardware controllers.
