Software Engineer | Informatics Student @ University of Washington

I'm a software engineer with experience in manufacturing systems, mobile development, and data frameworks. Currently pursuing my BS in Informatics at UW while working as a Teaching Assistant for Product Management.

I'm a Seoul-born software engineer with a unique journey spanning manufacturing systems engineering, military service as an interpreter, and education. My experience includes developing SQL procedures for automotive manufacturing systems used by Ford, Hyundai, Kia, and Tesla, building mobile viewers for factory data analysis, and currently mentoring 65 students in Product Management at UW.

I bring a meticulous approach to problem-solving, emphasizing root cause analysis and assumption validation—skills I've honed both in engineering systems and teaching others.

• Manufacturing Systems Development: Built SQL procedures for Manufacturing Engineering Systems deployed across international automobile plants (Ford, Hyundai, Kia, Tesla)
• Recall Prevention: Established back-trace mechanisms for product recall scenarios
• Mobile Innovation: Developed mobile viewer for real-time manufacturing status and data analysis
• Data Framework: Designed new framework improving timeline stamping accuracy and serial number parsing
• Cross-border Tools: Created Data Viewer tools enabling business owners to monitor Vietnamese factory operations

• Technical Translation: Translated 127 documents on Radio Communication Hardware as Interpreter Sergeant at USAG Humphreys
• Community Impact: Tutored Math, Chemistry, and Coding for veterans with hearing disabilities, developing specialized communication methods

• Teaching Assistant: Managing 65-student Product Management program at UW (INFO 380)
• Boot Camp Leadership: Led team of 12 instructors for AP/IB exam preparation at Sehan Academy
