About | Cartesian Supply Chain

About

I'm Steven Painter and I spent nearly 20 years living and working in Asia. I obtained my master's degree in Engineering in Taiwan and during my career there I managed supplier networks across semiconductor assembly, PCBA, optoelectronics, and electromechanical manufacturing. After returning to Canada in 2017, I continued traveling to Asia for supplier assessment work, visiting factories in Taiwan and China for clients who needed technical and regional expertise without a full-time Asia presence. This experience, combined with fluency in Mandarin, is what Cartesian Supply Chain is built on.

Track Record

The work has to pay for itself.

In a six-week engagement across nine suppliers in Taiwan and China, FX-protected agreements were negotiated, cost reductions achieved with four vendors, and a risk register built that identified critical gaps at two suppliers. The immediate savings from that engagement more than covered all consulting fees and travel.

What Sets This Apart

Skills that are hard to find
in one person.

The combination of Mandarin fluency, engineering background, legal representative experience, and executive-level commercial judgment is not common. Each element would matter on its own. Together, they change what's possible in an Asia engagement.

Engineering-led evaluation - can assess manufacturing process capability, quality systems, and technical risk directly, without relying on a translator.

Supplier quality methods - Lean Six Sigma, ISO 9001 certification and recertification. Has led quality teams including certified black and green belts.

Executive credibility - has presented make/buy decisions and supplier exit recommendations to C-suite. Can tell a CEO which supplier relationship to end and be believed.

Financial literacy in supply chain - put GMROI front and center at a national distribution business and secured adoption from sales leadership. Supply chain recommendations land in financial terms.
