Creative Projects

Flow Theory Visuals — Videography & Media Tools

📍 2022–present

A personal videography brand for capturing social dance culture, movement, and connection.

I've covered 20+ events in cities like Singapore, Taipei, Seoul, Mexico — helping dancers and festivals gain international visibility. Flow Theory content has reached global audiences, giving organizers marketing leverage backed by real numbers:

📸 Instagram (@flowtheoryvisuals)

1.5M+ reached
600K+ engaged

📺 YouTube (@flowtheoryvisuals)

700K+ channel views
16,5K+ hours watched

To support this ecosystem, I built a custom video-sharing app to host and monetize dance footage that doesn't get published on social media — replacing SmugMug Pro's $45/month plan and poor ROI with a zero-cost, self-hosted solution. The platform generated over $700+ in social dance videos within one year, proving sustainable and creator-owned infrastructure is viable.
