🚀 Turn your product idea into a clear, buildable direction — before you spend time and money on the wrong approach. Many early-stage products fail not because of bad ideas, but because key engineering decisions are made too late — or based on incorrect assumptions. I help founders and product teams define the right path early: what to build, how to build it, and what to avoid. 🧭 Start here (recommended) If your idea is still evolving or unclear, I recommend starting with a short feasibility session. In this session, we will: • clarify your concept and constraints • identify key technical risks • define a practical prototype direction This helps avoid unnecessary iterations and costly mistakes before moving into design or prototyping. 🔧 What I do I support early-stage product development from idea to validated prototype: • concept clarification and constraint definition • mechanical architecture and system direction • feasibility and manufacturability evaluation • prototype strategy and iteration planning • engineering decision support before major investment Rather than only delivering CAD, I help you understand the full path: idea → prototype → validation → next step ⚡ Accelerated exploration To improve speed and clarity, I use AI-assisted workflows and 3D tools to quickly explore and compare design directions. This allows us to evaluate options earlier and reduce unnecessary iteration later. ⸻ 🏭 From digital to physical With my own workshop and 3D printing setup, I can support: • functional prototype development • enclosure and mechanical validation • small-batch prototype builds • real-world testing and iteration 🎯 What you actually get • a clear and practical product direction • early identification of risks and constraints • a structured path from idea to prototype • confidence in your next steps Not just design — but clarity on what should (and should not) be built. ⸻ 🧠 Typical projects • consumer products and smart devices • enclosures and functional mechanical systems • hardware startup prototypes • proof-of-concept builds • early-stage product validation 📦 How I typically work Most projects start with a focused validation phase before moving into full design. This ensures: • the right direction is defined early • risks are identified upfront • time and budget are used efficiently From there, I can support further development, prototyping, and iteration if needed. 📩 Next step If you’re exploring a new product idea and want to move forward with more clarity and fewer mistakes, feel free to reach out.

Hello, Many startups and e-commerce brands struggle with unreliable suppliers, unclear manufacturing costs, and product designs that are difficult to produce. I help turn product ideas into manufacturable products and reliable supply chains in China through professional product development and product sourcing. Unlike typical sourcing agents who only locate suppliers, I combine product design expertise with manufacturing and supplier sourcing to evaluate product structure, materials, feasibility, and cost to identify the right suppliers and production solutions. I support the entire process from product idea → product sourcing & supplier research → prototype development and testing → manufacturing preparation → quality control → fulfillment and global delivery. Why clients work with me I provide product sourcing, supplier research, and product development services for clients who want to manufacture products in China. ✔ Reliable supplier sourcing in China – Structured supplier research with clear comparison reports to help clients choose the right manufacturing partner. ✔ Product design and manufacturing expertise – Ability to evaluate product structure, materials, and production feasibility. ✔ DFM-driven product development – Optimize designs for efficient and cost-effective factory production. ✔ Prototype testing and iteration – Support prototype development and design improvements before mass production. ✔ End-to-end supply chain support – From product idea and sourcing to manufacturing, quality control, and delivery. ✔ Dropshipping and fulfillment services – Support order handling, customized packaging, labeling, and global shipping for e-commerce brands. What I can help you with - Product Sourcing • Supplier research and identify reliable manufacturers in China • Supplier background investigation and credibility verification • Supplier comparison report (price / MOQ / lead time/capabilities) • Product market price analysis to evaluate competitive cost ranges • Supplier negotiation and cost optimization - Product Development • Product design evaluation • 3D modeling and design support (SolidWorks) • Structural optimization and material recommendations • DFM (Design for Manufacturing) analysis • Manufacturing feasibility assessment • Development of factory-ready production solutions The goal is to transform concepts into designs that can be manufactured efficiently and cost-effectively. I don’t just design parts — I design products that factories can actually build, and customers will buy. - Prototype and design iteration • Prototype strategy planning • 3D printed prototypes or sample coordination(FDM/SLM/SLA/CNC/Laser cutting) • Functional testing and evaluation • Design iteration based on test results • Optimization until the product is ready for stable mass production This iterative process helps reduce production risks before tooling or large manufacturing investment. - Quality & Delivery • Product inspection and quality evaluation • Production monitoring and supplier coordination • Packaging solution recommendations • Customized packaging and private label support - Dropshipping and order fulfillment • Dropshipping agent service • Order fulfillment and product handling • Packaging and labeling for e-commerce brands • Global shipping coordination These services are ideal for brands selling through platforms such as: • Amazon • Shopify Product Experience: • Industrial & consumer products | Fitness equipment | Electronics enclosures | Food-related hardware | Home furnishings | Tools My typical workflow Step 1 – Product understanding Understand your product concept, target market, cost expectations, and production requirements. Step 2 – Supplier sourcing & market analysis Research qualified manufacturers, analyze supplier capabilities, and prepare a structured sourcing and price analysis report. Step 3 – Product design optimization Evaluate the product structure and apply DFM principles to ensure the design can be efficiently manufactured and is cost-effective. Step 4 – Prototype & testing Develop prototypes or samples, perform testing, and design iterations to validate performance and manufacturability. Step 5 – Manufacturing preparation Select the most suitable supplier and prepare the production plan, including drawings, materials(BOM), tooling, and manufacturing process.

Your product looks great on screen. The ID is clean, the Kickstarter page is ready. Then the first factory sample arrives — and it's wrong. Snap fits don't hold. Wall thickness causes sink marks. The mold maker says "no problem" but quotes you three more rounds of revision. This is the gap I close. I'm based in Shenzhen. 14 years on the factory floor across consumer electronics — not managing remotely, physically present when tooling decisions get made. I've pushed 530,000+ units through mass production across 12+ product categories. The mistakes I've seen kill launches, delay shipments, and blow DFM budgets — I have them documented. I don't let them repeat on your product. What I actually do for overseas founders and ID studios: — DFM review before you cut steel: I flag wall thickness issues, draft angles, snap fit geometry, and shrinkage risk before the mold maker touches anything. One round of this saves you 2-3 revision cycles. — Factory translation: What your ID file says and what a Shenzhen factory actually builds are two different things. I bridge that gap in person. — NPI management: From prototype sign-off to first production run, I track tooling progress, first article inspection, and assembly line setup so you're not flying blind from 10,000 miles away. — Supplier selection: I know which factories in Shenzhen and Dongguan are honest about capacity and which ones will tell you what you want to hear. That knowledge took 14 years to build. If your product has plastic enclosures, mechanical assemblies, or mixed-material components and you need someone in China who will tell you the truth about what your factory is actually doing — that's the job.
