Co-founder and business lead at SANSANSUN Sports, a design-driven activewear manufacturer partnering with growing global brands.

Over the past decade, I’ve worked closely with founders, designers, and product teams across Europe, the US, and the Middle East—helping them turn ideas into scalable collections. My focus is not just on production, but on building repeatable product systems that support long-term brand growth.

I believe great activewear is not created by trends or price, but by the alignment of fabric, function, and user experience. Through our MDMD system (Material–Design–Manufacture–Delivery), we help brands reduce development risk, improve consistency, and move faster with confidence.

On this blog, I share insights from the factory floor, real client cases, and practical thinking on product development, fabric strategy, and scaling challenges in the activewear industry.
