   2026.05 – now · 4 months

   Work

   KIRAPAY & BILIBALA

   Product Manager · Hong Kong

   I built Sippa, to Projects from zero on my own — product, design and the full-stack build were all mine. A team of three joined once it existed and carried it on. Launched 2026.08.

   In progress

   • Model supply strategy, to AI capability for the group's creator-facing AI platform — which third-party models it can resell, under what constraints, at what cost.

   Shipped

   • BILIBALA's public website: design-system fork, copy and front-end implementation, the line owned end to end
   • The internal dashboard, new iteration
   • Invoices, Home 2.0 and Notification Center: specification and production code both delivered independently
   • Those three specs became the team's standard from definition through delivery
   • n8n chains and AI batch pipelines: identified and delivered unprompted, now the BD team's standing workflow
   • Supported BD on 10 prospective on/off-ramp partners; 4 signed, extending fiat coverage to 100+ currencies

   Work

   Grand Vigor Enterprises

   Product Designer · Part-time · Hong Kong

   Identified and eliminated two recurring manual processes: quotation generation and reporting, both automated by me and still running today, to AI capability

   • Both processes recurred weekly and neither was requested; the automation started from a quotation tool.

   • Rebuilt the product-visual pipeline around AI tooling: modelling, rendering, product imagery
