I'm Krstic Lei — industrial designer and product development consultant based in Asia. With a background in industrial design from Zhaoqing University and Folkwang University of the Arts (Germany), I've spent years working at the intersection of design, engineering, and manufacturing.
I work primarily with international clients — Amazon sellers, hardware startups, and consumer brands — who need a reliable partner on the ground in Asia to manage the full product development cycle.
Ongoing support on a monthly basis. Best for brands that need a reliable partner throughout their product development cycle — from sourcing to production follow-up.
Fixed scope engagements structured in phases. Each phase is scoped, priced, and billed upon completion. Best for defined projects with clear deliverables.
Whether you have a rough concept or a detailed brief, I'm happy to discuss how we can work together to bring your product to market.
