AI camp

AI Builder Lab with OpenAI, 11-12 June 2026

I was Selected Participant, AI Builder Lab by OpenAI Academy × DataKind. Collaborated with 5 mission-driven organizations as an AI Engineer and Evangelist to identify operational bottlenecks, explore AI-assisted workflows, and prototype solutions that improve execution speed and service delivery. Focused on disaster-response systems, researching how AI can transform SITREPs and fragmented operational reports into organizational memory systems that help agencies respond faster, coordinate more effectively, and continuously learn from past incidents.

Presented at Figma Show & Tell in Bangkok as an experiment in design-native AI tools and context-aware generation systems.

Ride Ads - Designed, and shipped it

Ads shouldn’t break the ride. We used thoughtful animations to keep it seamless then went beyond Figma where we couldn't envision it all, built it in code, and shipped.

Design experiment

Coupon Banner

91% uplift in CTR

27.38% pp uplift in purchase

I led a design experiment for an in-app coupon banner targeted at returning users and new users, whom we hypothesized to be more price-sensitive. By surfacing timely offers in a prominent banner, we aimed to turn their existing intent into completed orders. The winning variant delivered a 91% uplift in CTR and 27.38% uplift in purchase CVR versus control. This experiment became the starting point for a more systematic design-led growth experimentation practice at LINE MAN.
