Academic background
Research & academic contributions
Security & engineering work
Conducted hands-on pentesting in an authorized lab environment — identified exposed services, performed network enumeration, validated critical findings, and produced a structured remediation report using industry-standard tools.
Implemented SSL, secure payment gateways, and WAF on live e-commerce site TookTaakShop.com — ensuring PCI DSS-aligned security for real transactions.
Threat detection, pentesting, vulnerability assessment, and mitigation across various environments — documented findings and actionable remediation strategies.
Built a Smart Home prototype using C, Arduino IDE, and circuit design — automating gate control and device operation through a connected interface with IoT-style sensor integration. Associated with Kyungsung University.
Developed a Smart Shopping Cart prototype with card-based access, automatic cart-following, and secure transaction concepts — combining embedded systems, IoT control, and smart retail technology. Associated with Kyungsung University.
Real-time sensor-based decision systems for autonomous navigation and obstacle avoidance — integrating hardware control logic and embedded programming for reliable independent operation.
Designed a robot capable of climbing stairs via a mechanically adaptive wheel system — combining mechanical design, brushless motor control, circuit integration, and C/Python programming. Associated with Kyungsung University.
Built a small robot capable of dance-based movements through programmed control logic — combining motion control, circuit connection, and actuator-based motion into a fully working prototype. Associated with Kyungsung University.
