What I can help with

A supplier says their cell does X. Before you build a roadmap on it, you want to know whether the engineering holds. I run the claim through the relevant lenses and tell you where it's solid, where it's conditional, and what to verify next.

You need to know who actually makes the critical input, where the real bottleneck sits, and how concentrated the supply is. I map the tier structure, capacity, and chokepoints from public sources — so you're not sourcing blind.

You have a design, or a simulation, and no engineering presence in-country. I bridge the gap — structural and materials review, design-for-manufacturing input, supplier-facing engineering — so the thing that ships matches the thing you drew.

Before you commit to a material, a cell, or a component, you want a concise, engineer-vetted reference — properties, tradeoffs, what to check, where the sourcing risk lives. Short enough to use, rigorous enough to trust.

A spec sheet tells you what a pack is supposed to be. A teardown tells you what it is. I lead hands-on teardowns of production battery packs in China — cell format, module structure, thermal path, joining, and where the cost and the risk actually sit — with you in the room, reading the engineering as it comes apart. Scoped to your questions, arranged per engagement.
