My career began in smart factory manufacturing, where I managed complex quality systems as a Product Manager. This role was pivotal in mastering stakeholder coordination and operational strategy. By extensively testing hypotheses and building end-to-end systems from the ground up, I gained firsthand experience in navigating both technical successes and failures. These foundational years shaped my data-driven approach and my ability to lead projects with a clear focus on business impact.
High Integrated
Power Train System (HIPIS)
Role: Product Manager
Developed an end-to-end system to collect and analyze equipment data throughout the powertrain manufacturing process, providing actionable feedback to optimize production quality and minimize costs.
Architected a new database infrastructure that slashed query load times from 600s to 5s, significantly reducing reliance on legacy Oracle systems through strategic downsizing.
Standardized data protocols across 20,000 machines in 10 countries and implemented Statistical Process Control (SPC) to streamline global operations, resulting in a 30% reduction in manufacturing defects.
High Integrated
Vehicle System (HIVIS)
Role: Product Manager
Tailored for assembly lines involving high manual labor, this system focuses on bridging the gap between human operators and digital information to ensure consistent quality.
Integrated interactive kiosks and Smart Pens to digitize manual data entry, enabling seamless data collection from floor processes and enhancing overall workflow efficiency.
Improved Smart Pen recognition rates from 89% to 99.8% by training machine learning models specifically on Hyundai-specific factory symbols. Additionally, deployed advanced Bluetooth control technology to minimize signal interference within the industrial environment.
Mobile Inspection
System
Role: Lead Developer
Developed a mobile video inspection system to facilitate real-time communication between factory staff and external engineers, significantly reducing equipment downtime. This was the first mobile solution of its kind within the facility, built with a rigorous focus on industrial security.
As a pioneer of mobile tech in the plant, I focused on robust security measures including device authentication and unidirectional video processing, ensuring a secure yet user-friendly experience.
Evolved the system to integrate thermal imaging and oscilloscopes, expanding its utility to vendor quality inspections, service center investigations, and monitoring new factory expansions. Furthermore, I led several PoCs to integrate AR technology for enhanced remote assistance.
Today's choices create tomorrow's stories.
