AI / GAMES / PERSONAL NOTES

Hi, I’m
Boyu Zhang.

I also go by David. My gaming IDs are NoKiin and Harlen.

I’m based in Singapore and work on AI and games at Lobah. I build multi-agent systems that generate HTML5 games, as well as AI-native games. Before this, I worked on biomedical image analysis at A*STAR. I also used to play esports professionally.

I still play games after work. I also like travelling, going out for drinks, cooking and mixing drinks at home. I’m learning Thai too.

THAI / MINI GAME12 PHRASES

A little Thai?

I’m learning too. These are a few phrases for food and getting around.

สวัสดีsa-wat-di

Hello

These are short forms. For politeness, men commonly add ครับ; women use ค่ะ for statements and คะ for questions. The spelling hints do not mark tones.

    How are these numbers counted?

    A page view is recorded after about 3 seconds. Section changes do not add views, and rapid refreshes are deduplicated. Visitor counts are anonymous estimates based on IP and browser information; shared networks and device changes affect accuracy.

    Traffic statistics only publish aggregates and do not store raw IP addresses or use analytics cookies. Your current IP is shown only to you; looking it up records no page view or location history. Anonymous deduplication records are kept for up to 35 days; aggregate views are retained. Analytics respects Do Not Track and Global Privacy Control. IP location is approximate and may reflect a VPN.
