Ethan Gahng, a web developer from South Korea, won a hackathon with his Twilio-powered app Talk to the Future, which allowed users to schedule calls to their future selves and record audio messages. The app was later rebranded as WakeMyself.com and gained new features such as scheduling wake-up calls and capturing dreams through recorded audio messages. Ethan also created DayDream.fm, an app that adds realistic sounds to virtual reality experiences, inspired by ambient music. He aims to create engaging experiences without requiring user engagement, showcasing his creative talent and entrepreneurial spirit.
