Software engineer and founder.
Turning prototypes into products.

Hello, I'm Haris (ハレイス). For the past decade, I've helped startups, agencies, and enterprises build platforms people rely on. Many of those continue to serve millions of users today.

Lately, I'm focused on agentic loops, harness engineering, and the human element in the middle.

Based in 🗼 Tokyo. Usually running, reading, writing, or exploring the city.
