I build practical systems at the intersection of software engineering, AI, public-sector operations, and human-computer interaction.

• Building authentication and access-control systems for restricted network environments
• Working on AI/database management and translation support in a defense context
• Exploring human-computer interaction, mixed reality, and secure digital infrastructure
• Developing tools for local business digital transformation and public-service innovation

• Developed web platforms using TypeScript, Next.js, Tailwind, Firebase, and cloud services
• Built student-facing and public-service-oriented applications

• Worked on reinforcement learning and predictive churn analysis using financial data
• Interested in applied AI, database systems, and decision-support platforms

• HCI Student Assistant at Georgia Tech College of Design
• Worked with Unity, MRTK, and mixed-reality interaction systems

• Defense-related protocol, briefing, and terminology support
• Experience with military conference translation and manuscript editing
• Mandatory service period for ROK Army ends December 2026.
