ABOUT TIMEBRIDGE
TimeBridge grew from its creator’s years of living, interpreting and teaching between Korea and Vietnam. It goes beyond changing numbers to explain what makes sense to do now.
Start converting time→The same language needed a different explanation in every city and situation. Turning those gaps into useful, human answers became the starting point for TimeBridge.
01 · CREATOR STORY
Words that worked in Hanoi felt unfamiliar again in a Ho Chi Minh City taxi.
At nineteen, Heo Gan began living independently in Vietnam while working to cover daily and study costs, then took on interpreting and local coordination in Hanoi. In Ho Chi Minh City, a different accent made him a beginner again, and finding and contracting a home meant navigating countless conversations himself. Those experiences built a habit of reading people’s context before the numbers.
Studying Vietnamese and coordinating people on the ground in Hanoi turned differences in time and culture into lived experience.
He studied Vietnamese language and culture at Ho Chi Minh City University of Education while teaching, interpreting, developing course materials and content, and working in market localization.
Repeated questions about time differences, calls, rates and arrivals became a web tool designed for immediate understanding and action.
