About
I help product teams turn concepts into production-ready designs from mechanical parts and assemblies to custom PCBs and working prototypes.
My work spans both sides of product development: mechanical design and embedded hardware. That means I can design the enclosure, the internal assembly, and the control board that makes it function—without you needing to coordinate multiple freelancers.
What I deliver:
Mechanical Design (SolidWorks): Production-ready parts, assemblies, and manufacturing drawings. Design for Manufacturing (DFM) analysis, tolerance considerations, and assembly documentation .
PCB Design (KiCad): Schematic capture, multi-layer layout, Gerber files ready for JLCPCB or your preferred fabrication house, and complete Bill of Materials.
3D Printing & Prototyping: Design for additive manufacturing, topology optimization considerations, and STL/STEP file preparation for printing .
End-to-End Ownership: I don't hand off half-finished work. Every design is checked thoroughly before submission, and every deliverable includes documentation you can hand to a manufacturer.
Tech stack: SolidWorks, KiCad, 3D printing workflows, ESP32/STM32 integration.
If you have a product concept that needs mechanical design, a control board, or both, send me a message with your requirements. I'll tell you honestly whether I'm the right fit.
