About Me
I’m a multi-disciplinary creative with experience across e-commerce, product design, enterprise software, and creative tooling. I founded and ran an international e-commerce business for 9 years, designed physical products for the US market, spent 7+ years building enterprise SaaS integrations, and later created a video ecosystem that led to building my own platform.
I combine business sense, technical depth, and creative execution to solve problems.
Creative Projects
Flow Theory Visuals — Videography & Media Tools
📍 2022–presentA 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.
