Solynth - AI Economic Intelligence Platform
Solo-built economic intelligence platform for theme discovery/monitoring, combining a user-facing RAG chatbot (SSE streaming + session persistence) with an admin automation stack for ingestion, scheduling, and analysis/report workflows.
AI VC - Investment Intelligence
Solo-built investment intelligence service that ingests news/trends/macro indicators, runs a theme workflow (LangGraph when available, sequential fallback otherwise), and provides RAG-based Q&A with PII redaction and multi-provider routing/fallback.
AI Music Video Generation Platform
Solo-built AI music video generation platform that orchestrates external music/video providers, FFmpeg post-processing (composition/subtitles/overlays), and YouTube upload through Celery-based async workflows.
PentagonAI - Market Analysis Agent
Solo-built market intelligence backend: ingest → extract structured events (LLM) → canonicalize/merge (Qdrant similarity + LLM) → generate ImpactLinks → multi-agent council forecasts. Includes ops/debug endpoints for model routing and workflow visibility.
Project Agora - Agent Protocol
Solo-built hybrid (Web2 + on-chain) agent protocol designed for AI-agent participation: sponsors post jobs, agents submit work, and outcomes are verified via voting + reputation under staking/slashing rules. Includes a FastAPI server (jobs/submissions/votes/reputation), staking/treasury contracts, on-chain sync, a web UI, and a Python SDK.
SettleLab - Stablecoin Systems LMS
Solo-built stablecoin systems LMS that turns a Korean Obsidian research vault into a Next.js learning platform for issuance, redemption, signed payments, CCTP/L2 risk, RWA tokenization, account abstraction, x402 agent payments, security testing, and capstone labs.
2-DOF Azimuth Thruster
Developed an empirical mathematical model for a 2-DOF azimuth thruster to overcome the limitations of analytical modeling in complex hydrodynamic environments. The project aimed to derive a precise transfer function covering the entire frequency range (low to high) using the Signal Compression Method (SCM).
Laparoscopic Surgical Robot
Developed a handheld multi-DOF laparoscopic surgical device with detachable robotic tools (Patent KR102199910B1). The system overcomes the limitations of traditional manual tools by enabling precise articulation and rotation through an embedded control system, bridging the gap between manual and robotic surgery.
