Whether you're refining an existing product or preparing a new one for manufacturing, I help bridge the gap between industrial design and production.
I work with founders, product companies, and manufacturers to engineer products that are practical to prototype, assemble, and manufacture. My work focuses on internal architecture, tolerance development, mechanism design, DFM, DFA, and manufacturing documentation, ensuring products perform as intended while remaining cost-effective to produce.
My experience extends beyond CAD. Having worked alongside foundries, machine shops, fabrication, tooling, and production teams, I understand how engineering decisions affect manufacturing, assembly, quality, and cost. That practical experience allows me to identify issues early, before they become expensive tooling changes or production delays.
Typical projects include consumer products, industrial equipment, enclosures, mechanisms, wearables, reverse-engineered products, and manufacturing redesigns. Whether you're preparing for prototyping, low-volume production, or mass manufacturing, I deliver engineering solutions that manufacturers can confidently build.

What's Included

Product Engineering Review

Review of the existing design, manufacturing approach, and potential engineering risks.

Mechanical Design & CAD

Production-quality parametric CAD developed in SolidWorks with clean assemblies and design intent.

DFM & DFA

Design improvements to simplify manufacturing, reduce part count, improve assembly, and lower production cost.

Manufacturing Documentation

STEP files, native CAD, exploded assemblies, engineering drawings, and supporting documentation.

Tolerance Development

Critical fits, interfaces, stack-ups, sealing surfaces, and manufacturing tolerances, as defined where required.

Prototype & Manufacturing Support

Technical support during prototyping, supplier review, and design refinement before production.
